WBDG is a gateway to up-to-date information on integrated 'whole building' design techniques and technologies. If adhesives are used to attach an element to the membrane, the adhesive pattern should be installed in small dabs to allow vertical water discharge and reduce the potential for hydrostatic pressures imposed on the waterproofing membrane. Other available dampproofing technologies include both cementitious and reactive products. Asphaltic coatings may be solvent- or water-based. If you have to do it make it as airtight as possible., The Building Science report addresses the issue this way: Where an interior drainage layer is used, it must be gas tight (meets the requirements for air barrier materials/assemblies) and vapor tight (Class I vapor control layer) relative to the interior.. WaterWay Rainscreen Drainage Mats: Consists of a polypropylene core of fused, entangled filaments in varying thicknesses from a nominal 1/8 inch to 3/4 inch, depending on desired cavity space and cladding selection. Where the foundation wall is required to be waterproofed, adding a waterstop to the construction joint is recommended. Sq Ft: 325 Material Thickness: .45 inch Core Material: Polypropylene Free Shipping Need a written quote? The first two systems can be applied as negative-side or positive-side waterproofing. Sika Drainage Mat 1000 is suitable for heavy loads and split slabs exposed to vehicular traffic. But, he adds, just as water makes the bentonite swell, a lack of water makes the panels shrink. DELTA-MS is a dimpled membrane that uses our exclusive Air-gap Technology to ensure your basements stay dry and last longer. Waterstops are manufactured products available in a wide range of configurations and sizes. Who cared? Straube suggests a three-tiered approach to protecting the foundation, with the choice hinging on site conditions and budget. Drainage Mat 202. For most portions of the foundation wall, water removal and control is of prime importance. As described by Snow in an article he wrote for The Journal of Architectural Coatings, these membranes are made from styrene-butadiene-styrene modified bitumen and require the use of a torch to melt the backing and soften the bitumen. In general, using prefabricated composite drainage board directly against certain waterproofing membranes as a protection layer is not recommended. Apply 6-mil-thick polyethylene sheeting or a self-adhesive waterproof membrane to the entire exterior side of the below-grade walls before backfilling. Building Product Divisions > 07 - Thermal and Moisture Protection > 07 05 10 - Rainscreen Drainage Mat 07 05 10 - Rainscreen Drainage Mat. The lens membrane should slope away from the building and collect and redirect the runoff to a drain tile or sump away from the foundation. Understanding the specific chemical admixture is important in determining its potential performance in below-grade dampproofing or waterproofing applications. Other surfaces such as gas pipes, signal or electrical should generally be done with due consideration for the nature of the sleeve through the exterior wall and the depth below grade of the penetration. Bentonite panels are still common on commercial waterproofing jobs, says Geiger, and remain popular with some architects and builders. Aggregate adds additional weight-bearing to the foundation wall. The core is installed dimpled side down to allow water retention within the cups. ArmorDrain 150 Drainage Mat is considered a green product, and can be used toward LEED building credits. In some situations, it may not be possible to apply waterproofing directly and entirely to the foundation walls, and it may be necessary to fasten a "lens" membrane to the foundation wall to catch runoff and redirect it away from the foundation. xKn!DLKN"egorGE !u2:y So on a site where the foundation may be sitting in a foot or two of water, even seasonally, theres a lot of force to create leaks. The companys EasyDri is a single-component polyurethane thats used to treat a crack, not the entire wall, says brand sement menager Amanda Helber. If water gets through the dimple sheet, the dampproofing will prevent it from being absorbed by the concrete. On low risk sites where free-draining backfill and perimeter drains are provided, especially where basement use is limited, dampproofing may make sense to a developer looking for any way to cut costs. 8 sieve are suitable. This is . UGL Drylok Extreme is guaranteed to resist 15 feet of head and last for as long as 15 years. SKU 3811R-GR. . Liquid-applied waterproofing membranes may come in several grades, with a manufacturers better-quality products guaranteed for greater amounts of hydrostatic head. Structural Support, Environmental Control, Finish, and Distribution, are expanded in general terms for floor slab systems. Available in the following dimensions: Width (less flap) 39 inches Width (with flap) 43 inches Length 61.5 feet This swelling can be 10 to 15 percent of the thickness of the base material. This assembly, what he calls the biggest bang for the buck, should be able to cope with relatively wet conditions and work on all but the most challenging sites. The drainage board should have the protection sheet on the backside of the core to promote better movement against the insulation. Lateral loads on foundation walls exist from the soil, surcharge and hydrostatic pressure loads. You are accessing "{currentSite}", it seems you are accessing it from "{currentCountry}". The filter fabric helps prevent roots from affecting the efficiency of the drainage/aeration layer as well as retaining soil or other fine particles from being washed away and allows water to pass into the drainage core. Start your subscription today and save up to 70%. Stopping water leaks in an existing foundation is more complicated. Bentonite sheets are also typically shingle lapped with the lateral direction of the concrete placement. Faade terminations often produce the accumulation of moisture at or near the grade line of the building with the surrounding area. Cementitious SystemsThese systems contain Portland cement and sand combined with an active waterproofing agent. For application from the exterior, the next design decision is to use fluid applied or sheet products. This can be accomplished with pumping systems. The key question that remains is whether to provide dampproofing or waterproofing to the surface of the foundation wall or not at all. Additionally, the composite cores have sharp corners that can cut the waterproofing membrane during installation or backfill operations. . Prefabricated Synthetic Drainage LayersThese products consist of a combination of plastic composite drainage cores with adhered geotextile fabrics. A protective sleeve that is two sizes larger than the pipe is required for any pipe that passes through a concrete foundation wall or footing. When the basement is used only for storage or mechanicals, a little water once in a while may not be a big deal. Holes in drainage mats allow water and other liquid hazards to pass through the top of the mat, reducing the likelihood of injury from slipping. The foundation drain shown in Figures 1 and 2 can also be located on the interior side of the footing, or on both sides if necessary. As this Building Science Corporation paper explains, the concrete slab can be cut back along the edge, a trench dug to accommodate drain pipe and crushed rock, and an interior sump pump installed to get the water out of the basement. The sealant is pushed through the entire depth of the crack to plug leaks effectively, Stock said. First, lets keep in mind that Peter would be the last person to claim lab-like precision with his testing. Condition appraisals and trouble shooting of below-grade structures reveals common sources of leakage that occur at penetrations. An interior drainage layersuch as dimple mat or sheet waterproofing membranecan be added. Diligent inspection and repair of the waterproofing after reinforcing steel is placed is a critical step, as steel placement often results in damage to the waterproofing that can not be repaired once concrete is placed. Available Thickness: 6mm (.25") Roll Size: 39" x 61.5' Roll Weight: 16 lbs . The details, graphics, and related information shown in the details are intended to illustrate basic design concepts and principles only and should be considered collectively with the appropriate narrative sections of the Whole Building design Guide (WBDG). But before doing any work on the foundation itself, it might pay to inspect the grade around the house and the condition (or existence) of gutters and downspouts to make sure that runoff does not pool around the foundation but is directed safely away from the house. phone +1(201) 933-8800 Drkens version is called Delta MS. Waterproofing resists both vapor migration and hydrostatic pressure. Snow adds: These systems, however, require application by skilled installers and can be quite dangerous.. The slip plane can reduce stresses imposed on the membrane during controlled backfill operations; these stresses can cause membrane damage, wrinkling, loss of adhesion, or delamination. Construction joints have been effectively treated in most applications by a waterstop manufacturer's recommended details. About FOAMULAR INSUL-DRAIN. Asphaltic coatings are very common. With bentonite systems, lapping of bentonite sheets is typically backlapped from the exterior if concrete placement involves pouring from the top of the wall. This can be handled from the outside (positive side repairs) or from the inside (negative side repairs). Drainage boards cover the foundation from the ground level to the top of the footing. Concrete walls, either inside or outside, are flaking. This separation of differing soil types maintains flow rates of soils used as drainage layers and minimizes settlement from finer materials filling in more coarse materials. Structural Support, Environmental Control, Finish and Distribution, are expanded below in general terms for foundation walls. They include flexible cementitious coatingssuch as W.R. Meadows two-part Cem-Kote Flex STand panels made with a layer of sodium bentonite (a variety of clay) that expands to form a watertight barrier when it gets wet. Location of the slip plane may vary depending on the design; however, it should be included in all assemblies. When cracks in a concrete foundation are not structural, they can be repaired by injecting them with epoxy or urethane from the inside. The sheet is installed so the dimples face the foundation wall, creating an air space between the membrane and the foundation. Polyurethane-Methacrylate (PUMA) Technology, TREMproof PUMA for Below-Grade Waterproofing, TREMDrain Fittings and Accessories Data Sheet, TREMDrain Fittings and Accessories Instructions, TREMDrain Series Drainage Application Instructions, TREMDrain Series Drainage Mat App. Snow, on the other hand, prefers fluid-applied membranes because there are no seams or joints to detail. In blind-side (positive-side, without access due to tight lot lines, under slabs on grade, or other reason) waterproofing assemblies, products may include sheet materials of thermofusible HDPE or PVC, bentonite, or other similar proprietary sheet products. For some membrane applications such as hot-applied bitumen systems, the protection board is embedded into the wet membrane forming an integral part of the waterproofing membrane. Dampproofing/Waterproofing in all situations should be carried up above the upper screen and integrally tied into the building faade flashing and waterproofing. Home. These are EnkaDrain foundation drainage mats. Foundation Walls CHARACTERISTICS / ADVANTAGES . The Glen-Gery Drainage Mat is an all-wall engineered rain screen drainage and ventilation mat for all sidewall applications including manufactured brick and stone. When a dimple mat is placed against a concrete wall, the dimples make the plastic stand out from the wall, leaving a free-draining air space between the plastic and the concrete. When it is wrapped over masonry ledges, care must be taken to coordinate with masonry ties and thru-wall flashings. A few thousand bucks up front on a site where conditions are questionable seems like good insurance. Although marketed to be used with excavated soils during backfill in lieu of a granular drainage layer, it is recommended that a full system approach be used in applications where water leakage is not tolerable; a full system approach should include both a synthetic drainage layer and granular drainage layer. The Foundation Protection System that Keeps Basements Dry Protecting your foundations from water and moisture is critical. The use of a Tremco drainage mat provides the following advantages: 1. These materials can be solvent based or water emulsions. Waterproofing is more effective in eliminating the risk of leakage and may be no more expensive than dampproofing, depending on the material used. For example, crystalline waterproofing is often used to provide redundancy to one of the other waterproofing systems. The company suggested that Peter substitute SB Bonding Emulsion for some of the water in the NB 1 Grey mix and apply a primer (Polysill TG500) to the block before coating the CMU. The geotextile fabrics retain sand, soil, concrete, or grout allowing water to migrate into the free draining core. Blog Sign up for eletters today and get the latest how-to from Fine Homebuilding, plus special offers. Finish FunctionsTwo areas of finishes are of importance in relation to foundation walls. Moisture that penetrates through the upper screen needs to be directed to the exit drain located at the base of the foundation wall. The manual also recommends an expanding waterstop made of bentonite over a capillary break between the footing and the foundation wall. Do these interior moisture control systems really work? Fig. ft/roll Typically constructed with flexible PVC, permeable grout injection tubes are installed in construction joints and are injected with grout only if leakage is observed. These features, however, leave much to be desired with respect to sealing and waterproofing. Sealing these generally requires application of elastomeric boots that seal to the housing and to the exterior pipe. This is accomplished through a drainage system at the exterior of the wall that is typically a free draining granular material. Download Data Sheet get_app. Designed for all horizontal applications, HYDRODUCT 660 collects and transports water to drainage outlets. Some systems include reinforcing mesh embedded into the liquid. The key advantage to fluid systems is their monolithic nature and self-flashing abilities as the material is applied in liquid form. Readers are advised to obtain expert advice when designing systems which are below the water table or which are enclosing particularly vulnerable occupancies. When Peter tried plugging an active leak with Drylok Fast Plug hydraulic cement, the column continued leaking, including right at the plug. The information contained therein is not intended for actual construction, and is subject to revision based on changes and or refinements in local, state, and national building codes, emerging building envelope technologies, and advancements in the research and understanding of building enclosure failure mechanisms. The drainage core is composed of tough synthetic filaments. This high strength non-woven geotextile is designed to protect the drainage composite during and after construction. The first area is the finishes of the interior space. TREMDrain NW is a two-layer drainage mat consisting of a polystyrene core and nonwoven, needle-punched polypropylene fabric. The filter fabric retains soil or sand particles as well as freshly placed concrete or grout, allowing filtered water to pass into the drainage core. Important design considerations include sloping the surface away from the structure, providing a suitable drainage system from the upper screen through the granular backfill, and a synthetic drainage layer that extends down to the perimeter drain. Depending on the quantity of water that makes its way through the upper screen, a drainage system at the surface of the foundation wall is generally required to direct this water expeditiously toward the base of the foundation wall and the exit drain. Geotextile filter fabrics are also used for separating differing soil types in below grade enclosure applications. It is used for drainage, protection, filtration, and hydrostatic pressure relief. This excess moisture might be due to flooding or some other reason. It is recommended that a 60 mil PVC membrane or polyolefin membrane be used, set on a concave sand bed and fastened to the foundation wall with a stainless steel termination bar with standard waterproofing applied to the wall above that point. Browse companies that make rainscreen drainage mat and view and download their free cad drawing, revit BIM files, specifications and other content relating to . Assisting were Judd Peterson of Judd Allen Group and David Young, P.Eng., P.E. Drainage board, such as Drkens Delta-Drain, is similar to dimple mat except that the dimples face outward and are covered with a layer of geotextile material. Foundation WallTypical System (Detail1.2.1)DWG|DWF|PDF, Foundation Wall SystemBlind-Side Waterproofing (Detail1.2.2)DWG|DWF|PDF, Foundation WallFluid-Applied Membrane System (Detail1.2.3)DWG|DWF|PDF, Foundation WallSheet Membrane System (Detail1.2.4)DWG|DWF|PDF, Foundation WallPipe Penetration Detail Without Sleeve (Detail1.2.5)DWG|DWF|PDF, Foundation WallPipe Penetration Detail With Sleeve (Detail1.2.6)DWG|DWF|PDF, Foundation WallFaade Transition to Masonry Veneer (Detail1.2.7)DWG|DWF|PDF. After spraying on a 60-mil layer of styrene-butadiene rubber, Risinger explains in this article in the Journal of Light Construction, he adds a heavy bead of sealant at the cold joint between the wall and the footing. Water that makes its way past the face of the sheet should make run down to perimeter drains at the base of the wall without hydrostatic pressure that would cause problems. ArmorDrain 400 Drainage Mats are designed to provide drainage in extreme cases involving heavy loads or heavy traffic, such as under slabs, planters, retaining walls, bridge abutments, foundation walls and roof gardens. In general, when properly designed, non-woven products have good filtration and separation properties. Sheet products are advantageous in terms of consistency in product material properties and thickness, but the primary drawback is the numerous laps that are required. We have a dedicated website for your country. Common practice for wall terminations or door entries is to provide slope away from the building as previously indicated. Maine builder Ben Bogie uses a peel-and-stick waterproofing membrane or a fluid-applied waterproofing product, also in combination with dimple mat and perimeter drains. The thickness of these systems varies from 20 to 120 mils. Drainage mat allows for full head-to-footer flow of water.5. To do so, Peter built hollow columns of 8-by-8-inch masonry block and waterproofed the outside according to directions provided by the manufacturer. concrete or concrete masonry units. endstream In combination with bentonite sheet waterproofing, these voids can be detrimental, since the bentonite can swell into the voids and loose its waterproofing integrity. Sika Drainage Mat 1000 Sika Drainage Mat 1000 consists of a high density polyethylene geonet drainage core with its ridges heat fused to a layer of nonwoven polypropylene filter fabric on the top side and a heavy duty non-woven polypropylene membrane protection fabric on the bottom side. The location of the building will inform (1) the amount of drainage provided and (2) the amount of insulation in the assembly. 9 0 obj What is the minimum thickness of mat foundation? Penetrations can also become quite exotic such as steam penetrations or other features that require special treatment. They are used in wet areas such as kitchens and other environments requiring frequent washdowns. The heat fuses layers together and overcomes some of the shortcomings of self-adhering membranes by providing complete coverage of joints and other details. 201 Polito Avenue of RDH Group, Scott A. Harvey, AIA, RWC, LEED AP of Applied Building Sciences, and Joshua Kelly of Simpson Gumpertz & Heger Inc. Innovative Solutions for the Built Environment The actual design and configuration will vary based on applicable local, state, and national building code requirements, climate considerations, and economic constraints unique to each project. Many drainage mats also include a polyethylene sheet backer to uniformly disperse the loads imposed on the membrane and reduce the potential for damage caused by non-uniform profiles (dimples) in the composite core. fax +1 (201) 804 1076. Personally, I think its a terrible idea, says Barrett, who adds that radon is the second leading cause of lung cancer in the U.S. after smoking. In areas with greater moisture loads from hydrostatic pressure from high water tables or sensitive interior environments, a waterproofing membrane should be applied to the exterior surface of the foundation wall in lieu of dampproofing. Width 1 m, 1.5 m, 1.8 m, 2.0 m, 2.9 m, 3 . With fluid membrane systems, proper application in terms of coverage and thickness is critical to performance, and this should be monitored throughout the installation. But few in the business would argue that even a successful retrofit is better than keeping water out of the basement in the first place. Foundation drain is an exterior drainage system installed on the outer face of the foundation wall and near the wall footing, covered with a layer of gravel, serving the purpose of draining out excess water seeping into the foundation. Attach mat to membrane surface with Sikaflex 11FC or approved adhesive as necessary to keep in position. This upper screen may consist of relatively permeable landscape areas ranging to impermeable pavers, concrete or asphalt surfaces that will shed the majority of surface moisture. Warning: This video contains flashing images that could trigger seizures for people . Condensation is possible in below grade conditions in warmer more humid summer conditions as below grade spaces tend to be cooler in the summer because of the insulating effect of the backfill soil. Thats what Peter set out to learn. . For emerging issues refer to General Overview section. The sump basin is always capped with a lid that is vapor and air tight. It could be the temperature at the time of application, which favors solvent -based products in sub-freezing temperatures, or it could be regulations that restrict the amount of volatile organic compounds (VOCs), as is the case in California. In fact, in some situations, conditioned below grade spaces are subjected to a constant inward vapor drive during summer as the interior space is air conditioned, and in the winter the interior space is heated resulting in a lower vapor pressure than the exterior condition as the soil stays relatively constant in terms of vapor pressure. Resources In general, drainage core widths of 1/4 to 1/2 inch provide drainage flow rates 3 to 5 times the rate of commonly used natural backfill materials. Environmental Control FunctionsThe exterior environment that the foundation wall is subjected to includes environmental control loadings such as thermal, moisture, tree roots, insects, and soil gas. In the vast majority of cases, residential cases, dampproofing is more than adequate, says Barrett. Minimum thickness of concrete structural elements based on ACI 318-14, IRC 2009, IS 456 2000, and UBC 1997 is presented. If you are unsure what level of protection is right for you, please contact us. Become a member and get unlimited site access, including the % Moisture in the soil cause the bentonite to expand, sealing out ground water. Green Roof Drainage Mat - EnkaDrain 3811. As most foundation wall systems have substantial mass, e.g. Basements are increasingly becoming in-law suites, man caves and home theaters where finish materials rival those in above-grade parts of the house, Straube says. For really wet sites, with lots of water expected in the soil, or in situations where the living space inside the basement is especially vulnerable to moisture, Straube recommends another step up. Soil loadings vary with soil type and whether soil is treated as active or passive. If installed, soil pressures can cause the "dimples" in the drainage core to displace or damage the waterproofing membrane. Structural Support FunctionsThe foundation wall system of the below grade building enclosure must be designed and constructed to support both vertical and lateral loadings. Sika Drainage Mat 1000 Sika Drainage Mat 1000 consists of a high density polyethylene geonet drainage core with its ridges heat fused to a layer of nonwoven polypropylene filter fabric on the top side and a heavy duty non-woven polypropylene membrane protection fabric on the bottom side. Where sheet materials are utilized, it is preferred to adhere the membrane fully and continuously to the substrate to prevent lateral migration of leaks, and to heat-weld or positively bond the seam laps. For foundation wall applications, typical cold applied fluid applied systems are approximately 60 mils in thickness. This is called spalling. Cosella Dorken Products. At times these systems are run internally in the interior surface finish system or in ceiling space. Insulation materials used in below grade enclosure applications are primarily limited to rigid extruded polystyrene board due to the need for high compressive strength and moisture absorption resistance. Sika Drainage Mat composites are available in both high flow dimpled core and high crush resistant geonet constructions. Most of the time, waterproofing is not needed residentially.. The H8 version will handle 8 feet of head while the XTS, used in both residential and light commercial work, will resist 12 ft. of hydrostatic head, according to the company. When designing the thermal, protection, and drainage elements to the exterior of below grade foundation walls, a slip plane should be introduced vertically within the assembly. When using cast-in place concrete, detailing of the form ties is critical and using single sided forms braced back to the slab can minimize this detailing. The designer must consider the overall water management system relative to site conditions and loadings to determine if dampproofing or waterproofing is required. Since dampproofing cannot withstand hydrostatic pressures, it should not be used on structural elements below the water table where the intent is to prevent interior water leakage. The general solution to the problem is encasing the foundation in a waterproof membrane with seams sealed, and then having a drain tile to prevent water from rising around the foundation, which would create hydrostatic pressure that could aid water incursion through any small breaches in the membrane. Dampproofing is intended to control vapor diffusion through the foundation, which can contribute to damp conditions on the interior. The outlet must be the lowest point in the system at each juncture. In some cases, the tubes may also be re-injected if leakage persists. Drainage mat does not. One of them, Texas-based Matt Risinger, starts with a liquid-applied or peel-and-stick membrane that is applied directly to the foundation wall (he fills any large voids with mortar first). Multi-Composite Drainage and Protection Boards TREMDrain Total Drain is designed provide a value engineered alternative to perforated pipe and aggregate subsurface drainage systems in applications requiring high strength and high flow capacity. Portions of the building permanently below the water table may require more redundant systems. 3. concrete, insulation may only be of importance to moderate interior temperatures in the upper portions of the foundation wall where temperature conditions will fluctuate. Contractors like U.S. Waterproofing have a variety of options for tackling repairs from the inside. When pumps are to be relied upon to discharge moisture, a backup power system should be provided in the event of power failure. %PDF-1.7 Based on our current knowledge, these products are not classified as dangerous Peel-and-stick and liquid-applied membranes are common on residential sites, but manufacturers offer several other options.
