If installed, soil pressures can cause the "dimples" in the drainage core to displace or damage the waterproofing membrane. Most waterproofing materials also control vapor diffusion. Approved materials include bituminous coatings (asphalt that has been diluted with solvents) acrylic modified cement, or surface-bonding cement. Sign up for eletters today and get the latest how-to from Fine Homebuilding, plus special offers. Drainage mat can be fitted with outlets and drainage accessories to further move the water away from the structure. The companys EasyDri is a single-component polyurethane thats used to treat a crack, not the entire wall, says brand sement menager Amanda Helber. 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. Notre that leakage may occur at a penetration and flow behind the waterproofing if a lateral path exists. This high strength non-woven geotextile is designed to protect the drainage composite during and after construction. Design considerations include selecting an appropriate design to achieve the required flow rate. After Peter wetted the block with water and rubbed in Xypex Patch-n-Plug, the leaks disappeared. While the first control of these abnormal load events are through security entry control systems and restricted access, structural design considerations may also be required in the design of the foundation wall system. Most building codes require dampproofing as a minimum amount of moisture protection. Insulation hangers may be set into wet daubs of Tremco membrane. 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. Dryvit Drainage Mat is a flexible, thermally preformed, in a zigzag configuration, mat made of polyamide and produced in a pale blue color for identification. The sheet is installed so the dimples face the foundation wall, creating an air space between the membrane and the foundation. As moisture moves from the upper screen through the drainage system on the exterior towards the exit drain, moisture will inevitably make its way toward the surface of the foundation wall itself. Thermal considerations are of limited concern as one gets deeper down on the foundation wall as there is a constant, thermal design condition on the exterior. Other available dampproofing technologies include both cementitious and reactive products. Sika Drainage Mat are manufactured articles/finished goods that do not require Safety Data Sheets to be marketed, transported or applied at the jobsite. For uneven rubble foundations, a layer of spray foam insulation can be applied over the waterproofing membrane, as the illustration below shows. Contractors like U.S. Waterproofing have a variety of options for tackling repairs from the inside. 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. Perimeter drains of 4-inch Schedule 40 PVC covered with coarse gravel or septic rock in filter fabric completes the installation. Blind-side systems are typically either a waterproofing sheet or an impermeable clay-based material. The outlet must be the lowest point in the system at each juncture. ft/roll and installing gutters, perimeter drain pipe, a capillary break, and free-draining soils or drainage mat protect the foundation from water saturation. 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. For emerging issues refer to General Overview section. Alternately, hell use a peel-and-stick membrane 40 mils thick over a primer. This swelling can be 10 to 15 percent of the thickness of the base material. These details must be properly detailed and installed to be effective. Given that, you could have a foundation drainage problem. Depending on site conditions and depth of the foundation wall, positive side waterproofing can either be installed from the exterior or directly to the lagging in a blind-side application prior to placing concrete. Cementitious SystemsThese systems contain Portland cement and sand combined with an active waterproofing agent. Quantity Add to cart PRODUCT SPECS Model: 3611R Weight: 54 lbs Size: 39" wide x 100' long (27" dia.) Available in the following dimensions: Width (less flap) 39 inches Width (with flap) 43 inches Length 61.5 feet 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. Roll size: 4 X 50 200 sq. The drain should be placed below the top of the footing. Condition appraisals and trouble shooting of below-grade structures reveals common sources of leakage that occur at penetrations. But experts caution against coating an entire wall with a urethane or epoxy sealer that is not vapor permeable. However, since some municipalities charge for water pumping into storm drain systems, these costs must be weighed over the life of the structure when designing the waterproofing systems. Many waterproofing membranes need to be shielded from ultraviolet radiation to prevent deterioration and as such some type of exterior finish is required. Foundation Membrane Material Plastic Coverage Area 520 square foot Thickness 5/16 inch Overall Length 780 inch Overall Width 96 inch Compatible Surfaces Concrete Block, Concrete Shipping Dimensions 96.00 H x 12.00 W x 12.00 D Shipping Weight 70.0 lbs Return Policy Regular Return (view Return Policy) Structural Support, Environmental Control, Finish, and Distribution as they relate to the below grade enclosure elements of foundation walls. When cracks in a concrete foundation are not structural, they can be repaired by injecting them with epoxy or urethane from the inside. Drainage mat can be fitted with outlets and drainage accessories to further move the water away from the structure. Early morning TV viewers in Portland, Maine, sooner or later will meet Tony Hafford, founder of T.C. Geotextile fabrics are typically constructed using polypropylene, polyester, or nylon and are available in either woven or non-woven designs. Repairs from the outside involve digging a trench on the outside of the foundation, adding perimeter drains if they do not already exist, and adding dimple mat or another type of membrane to the outside of the foundation wall. a slope of at least 1/8 inch per foot of drain or 1 percent should be provided). A liquid membrane cant covered with an elastomeric flashing extending to the edge of the footer and several inches above the cant has proven historically effective. Reactive/crystalline products are typically proprietary blends made from cement, silicates, metal oxides, and chemicals introduced through concrete admixtures or surface-applied applications. Drainage Mat 202. Bentonite sheets are also typically shingle lapped with the lateral direction of the concrete placement. Thats s no longer the case. Drainage mat does not. Sika Drainage Mat 1000 is suitable for heavy loads and split slabs exposed to vehicular traffic. 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. The inherent difficulties of fixing water leaks on an existing foundation are a good reason to consider doing more than simple dampproofing when you have the choice. Hot applied, rubberized asphalt systems can be 125 mils to 180 mils thick, plus embedded 60 mil neoprene sheets. Flower beds, overhanging decks, nearby neighbors and a variety of other site conditions may make this difficult, and it will be expensive. If in doubt, it is clearly prudent to err on the conservative side and provide a waterproof system. Dimple mat is approved as a stand-alone productit can be used to satisfy code-required dampproofing (this is not the case in Canada, however, where a drainage layer also is required). Pressing the Escape (ESC) button will close the modal and bring you back to where you were on the page. Laps should be installed so that the upper sheet is lapped over the lower sheet so that water is shed naturally across the lap. TREMDrain NW is a two-layer drainage mat consisting of a polystyrene core and nonwoven, needle-punched polypropylene fabric. The foundation wall of a building may be a cast-in-place concrete retaining or basement wall or a structural wall complete with load-bearing pilasters. endobj There are other back-up systems that can be employed in wall/floor construction joints, including injection tubes that can be installed in the joints prior to concrete placement and then injected with chemical grout after construction if the waterproofing and waterstop lines of defense are not completely effective. The geonet core is highly crush resistant yet flexible enough to conform to irregular surfaces. Thats the thinking behind Risingers approach, and Stocks experience on the retrofit side would seem to back him up. Fabric covered channels drain water from vertical foundation walls. Aggregate backfill needs to be trucked to the site and the dirt backfill hauled from the site. And for that, any amount of water is a potentially serious problem. Contractors have successfully used daubs of the Tremco membrane originally used to waterproof the foundation. Shotcreting can result in undesirable conditions such as voids behind reinforcing steel, and as a result some waterproofing manufacturers do not recommend their products for this application. Click to enlarge. Distribution FunctionsFoundation walls may contain distribution systems such as electrical and electronic runs. Tremco also offers a negative side spot treatment for cracks. In one of what he calls his Wingnut Real-World Tests, GBA technical director and building consultant Peter Yost experimented with several waterproofing compounds: UGL Drylok Extreme, Koster NB1 Grey, and Xypex Concentrate. The second area is the finish to the exterior near grade level. Positive-side waterproofing systems are post-applied to the surface of the element that is directly exposed to moisture, typically the exterior side of the foundation wall. concrete, insulation may only be of importance to moderate interior temperatures in the upper portions of the foundation wall where temperature conditions will fluctuate. Special loadings such as blast loads are a design consideration in parking areas under and next to buildings. endstream Contents: [ show] Components and Working of Foundation Drain DELTA-MS is a dimpled membrane that uses our exclusive Air-gap Technology to ensure your basements stay dry and last longer. Request Online $ Volume Pricing on Large Orders 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. Structural Support FunctionsThe foundation wall system of the below grade building enclosure must be designed and constructed to support both vertical and lateral loadings. TREMDrain NW provides an economical solution for single-sided subsurface drainage applications requiring a typical non-woven filter fabric bonded to a lower compressive strength and moderate flow capacity formed core. The performance of the foundation wall system depends on its ability to control, regulate and/or moderate these environmental control loadings on each side of the foundation wall to desired levels. One is that they will not span any cracks that develop in the foundation walland foundation cracks are viewed as all-but-inevitable. . The thickness of these systems varies from 20 to 120 mils. After waiting two weeks and retesting, Peter found no water leaks at all on the column. Dampproofing is not intended to control liquid water leakage through the foundation wall; waterproofing is required to control water leakage. It combines bentonite and a high-density polyethylene sheet that is installed on the outside of the foundation before backfilling. A variety of sheet- and liquid-applied membranes can be used, all designed to resist the hydrostatic pressure of ground water. Some wet basement issues can be solved with these steps alone. The bottom protection fabric provides cushioning for the waterproofing membrane. Standard Drainage Mats. These walls may also be used in the lateral resisting system for the building. 3-D Drainage Mat for Advanced Moisture Protection in Exterior Wall Systems FEATURES/BENEFITS Product Information Sheet . 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. The code permits a variety of waterproofing materials (even rolled roofing), but the most common for residential work are probably liquid-applied and peel-and-stick sheet membranes. <>stream Sheet-Membrane SystemsSheet membranes used in foundation wall applications include thermoplastics, vulcanized rubbers, and rubberized asphalts. 2. concrete or concrete masonry units. This site is protected by reCAPTCHA and the Google. Designed for all horizontal applications, HYDRODUCT 660 collects and transports water to drainage outlets. Some but not all sheet membranes are applied over a primer, and manufacturers offer versions that can be applied in temperatures as low as 0F. 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. Methods for concrete placement include cast-in-place between the lagging and interior forms, or spray applied shotcrete. One potential risk from this approach is that unless youre careful cutting back the slab and opening the floor creates a pathway for radon, a naturally occurring radioactive gas, to enter the house. Hydrostatic pressure can push the coating off the wall. This is called spalling. 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. 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 is accomplished through a drainage system at the exterior of the wall that is typically a free draining granular material. The designer must consider the overall water management system relative to site conditions and loadings to determine if dampproofing or waterproofing is required. This cooling effect combined with general poor air circulation in underground spaces can result in condensation on interior wall surfaces. One of the reasons that builders may stick with simple dampproofing is cost, says Steve Geiger, product group manager for W.R. Meadows. The first two systems can be applied as negative-side or positive-side waterproofing. Therefore, a protection layer is recommended between the waterproofing membrane and the drainage layer. xKn!DLKN"egorGE !u2:y 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. Clay panels and geotextile sheets are popular for use in blind-side waterproofing applications such as on retaining earth systems and elevator and sump pits. Areas designed as pedestrian areas should also include consideration for emergency vehicular loadings. Straube suggests a three-tiered approach to protecting the foundation, with the choice hinging on site conditions and budget. 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. The water flow rate is equal to or better than the aggregate backfill.2. 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. Xypex balked at Peters test method, arguing that CMU blocks differ too much in composition to allow a reliable seal. Fluid-applied membranes are applied in liquid form and cure to form one monolithic seamless membrane. Every variant of EnkaDrain foundation drainage mats is based on the same basic concept: A three-dimensional composite that consists of a drainage core either connected to one or sandwiched between two nonwoven geotextile fabrics. Revised by the Chairs of the Building Enclosure Councils with assistance from Richard Keleher, AIA, CSI, LEED AP and Kenneth Roko, AIA of The Facade Group, LLC The manual also recommends an expanding waterstop made of bentonite over a capillary break between the footing and the foundation wall. What are the advantages of a Tremco drainage mat versus aggregate backfill? The core is perforated, then bonded to a root resistant non-woven polypropylene filter fabric on the top side and nonwoven polypropylene membrane protection fabric on the bottom side. In soils that go through repetitive wetting and drying cycles, the panels eventually show signs of wear and become less effective than if they had stayed wet all the time. Positive drainage should be established underneath structural slabs with crawl space. The slip plane is between the XPS and the drainage board. An option used less frequently is a thermofusible membrane. Hammer & Hand uses essentially the same procedure. Drainage mat allows for full head-to-footer flow of water.5. Penetrations can also become quite exotic such as steam penetrations or other features that require special treatment. Prefabricated synthetic drainage layers are sometimes used in lieu of protection board for protecting waterproofing membranes. Long-lasting Moisture Protection, Long-lasting Satisfaction This can be accomplished with pumping systems. WBDG is a gateway to up-to-date information on integrated 'whole building' design techniques and technologies. These flashings are usually stainless steel to resist corrosion in contact with grade soils and moisture. 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. When builders combine these products with below-grade perimeter drains, and sensible site grading and gutter systems that carry rainwater away from the house, the chances of keeping a basement dry start to look very good. Waterproofing membranes can be categorized into four (4) types: Fluid-Applied SystemsThese systems include urethanes, rubbers, plastics and modified asphalts. 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. The sump basin is always capped with a lid that is vapor and air tight. The liquid is the carrier, says Russ Snow, sales manager and product group manager for W.R. Meadows, but the products are essentially the same once the liquid has evaporated and the coating has cured. If heat-welded seaming is employed and loose-hung membranes are tough and protected from damage by protection board, they may be effective waterproofing materials, but if a leak occurs, the leak will be difficult to locate and correct due to the loose application of the waterproofing layer in those cases. The geotextile keeps sediments out, and the textured surface of the membrane creates an air gap to relieve hydrostatic pressure. Based on our current knowledge, these products are not classified as dangerous The heavy fabric prevents rocks and dirt coming entering the drainage channels. Where expansion and contraction of the services or pipes entering the building occurs, a sleeve through the wall that is discontinuous with the penetration piping is required. 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. Expert advice may also be necessary when dealing with field conditions. Different versions of this type of product have filter fabric attached to the dimpled side which is then installed away from the wall and forms the route for water to flow down to the drain. 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. 9 0 obj The drainage board should have the protection sheet on the backside of the core to promote better movement against the insulation. The drainage core is composed of tough synthetic filaments. However, the use and location of the insulation is more important on the control of moisture in terms of preventing condensation on interior wall faces for the entire height of the foundation wall. 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. These systems include metallic (metal oxide), crystalline, chemical additive, and acrylic modified systems. A special flashing behind face stones of buildings or special flashing and treatment of the exterior slab edge where it is adjacent to ground features is required. Waterproofing resists both vapor migration and hydrostatic pressure. Bentonite clays act as waterproofing by swelling when exposed to moisture thus becoming impervious to water. Although the composite board may have a polyethylene sheet on the membrane-side, this sheet is often cut, damaged, or missing. Trusted, comprehensive guidance from the pros for a home that is healthy, comfortable, and energy efficient. 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. We have a dedicated website for your country. These are EnkaDrain foundation drainage mats. Distribution systems within the foundation walls themselves must be treated with careful consideration, as they can also be conduits transporting air and moisture within the structure. of standing water is equal to 250 pascals, the same as a 70-mph wind. One difference is that 16-inch sections of the slab are left intact every 15 to 20 feet to keep the foundation wall stable, as the illustration below shows. Manufacturers of Rainscreen Drainage Mat. Construction joints have been effectively treated in most applications by a waterstop manufacturer's recommended details. (This assembly looks a lot like an above-grade rainscreen wall, with the dimple mat taking the place of exterior cladding, and the dampproofing filling the role of a water-resistive barrier.). Readers are advised to obtain expert advice when designing systems which are below the water table or which are enclosing particularly vulnerable occupancies. See appropriate sections under applicable guide specifications: Unified Facility Guide Specifications (UFGS), VA Guide Specifications, Federal Guide for Green Construction Specifications, MasterSpec. Special emphasis is placed on evacuating the water at the wall base to avoid water build-up in the back fill or drainage system. 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. 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. What adhesives may be used for installing drainage mat to Tremco below-grade waterproofing membranes? No one size fits all, he said in a telephone call. Drainage mat for foundation wall Air sealing is critical. But, he adds, just as water makes the bentonite swell, a lack of water makes the panels shrink. 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.
