2 INTRODUCTION The Problem Since historic times, civil engineers and builders have used crushed stone (aggregate) or a combination of stone and some sort of pipe for soil drainage. While providing reasonably satisfactory results, aggregate drainage has several drawbacks. Clean and properly sized material is often expensive or not readily available. Transportation is expensive due to weight and volume. Quality control requires close monitoring of material and construction. Waterproofing materials have to be protected from damage from the aggregate and installation equipment. Aggregate tends to clog with soil over time, thereby reducing drainage capability. Despite great care in the design and construction of aggregate drains, their limitations often result in increased hydrostatic pressure, which increases loads on the structure and allows moisture intrusion into the structure. The Solution The availability of plastic geotextile filter fabrics in the 1960's led to the development of prefabricated plastic drainage material. This new type of drain, sometimes referred to as prefabricated drain, combined the soil retention capability of geotextiles with the water carrying capacity of specially formed plastic drain cores. The result was new and cost effective drainage materials for subsurface soil drainage. Continual development over the past forty years has resulted in today's prefabricated sheet drains that are now available with a wide choice of size, compressive strength, flow rate, filtration, and chemical resistance to suit virtually any drainage application. AKWADRAIN Strip Drain Prefabricated sheet drains have two components that act as replacements to the aggregate system 1) The geotextile replaces the aggregate function for water collection and allows the water to enter the drain without clogging the core and ) the formed plastic core replaces the pipe function for transporting the collected water. Sheet drains typically have a flat back, which is placed against the underground structure. For use against soft waterproofing materials, drains may have a film attached to the backside to protect waterproofing material from flowing into the back of the cones in the drain. Water, which flows through the fabric and into the core, is removed in several ways depending upon the drainage situation. One of the newest methods is through the use of the AMERDRAIN TOTAL-DRAIN system, which has a larger profile core at the bottom to serve as a high flow conduit to move water to the designated drainage exits. AMERDRAIN TOTAL-DRAIN system

3 Architects, engineers and owners are always looking for ways to reduce initial costs and extend the service life of all construction products. The desired result is a sustainable, high performance structure at an affordable price. To this end, AMERDRAIN sheet drain offers the following benefits: Low Installed Cost Combined installation and material cost is usually less than half of that for aggregate drains. Easy To Handle And Install Lightweight (less that 5 oz/ft, 0.4 kg/m ), easy-to-handle sheet drain is placed easily and quickly. No heavy equipment or skilled laborers are required. Inexpensive to store and transport. Reduces Drainage System Space Requirements Thicknesses of 1/4 (6 mm), 7/ (11 mm), and 1 (5 mm) require much less space than aggregate drains. Strong And Durable Crush strength of core resists damage during installation. High tear and puncture strength of fabric insures no damage during backfilling or use. Simple Inspection Visual inspection of material and installation is easy and less time consuming. Chemically Resistant Both core and fabric are resistant to all naturally occurring soil materials. Optional fabrics and cores are available for unusual chemical situations. High Flow Capacity, No Clogging Structure of core provides multiple channels for vertical and horizontal water flow. Filter fabric permits high volume entry of water into core while restraining soil particles. Enhances Waterproofing Polymeric core is impervious to water. Water seepage to wall is minimized therefore extending the life of the waterproofing. Protects Waterproofing Drain also serves as protection board with an optional backing film to protect waterproofing. Predictable Performance Uniform properties and quality assure predictable performance. Holds Reinforced Shotcrete Formed core provides good surface for adhesion of shotcrete and other construction materials.

4 DRAINAGE SYSTEMS TO FIT YOUR Foundation Walls AMERDRAIN sheet drain used on the outside wall intercepts ground water before it reaches the structure. Water is easily routed by the TOTAL-DRAIN system to a discharge pipe or sump. The sheet drain reduces hydrostatic pressure load on the walls and slab, which may permit a less expensive structure. Sheet drain also protects waterproofing and aids in keeping moisture from entering the basement, as well as reducing heat loss into the surrounding soil. Concrete Wall TOTALDRAIN Sheet Drain Optional Sand Layer for concrete curing Floor Slab Retaining Walls & Bridge Abutments Use AMERDRAIN sheet drain to reduce hydrostatic pressure from the backfill behind the wall and maintain the stability the entire height of the wall. Retaining Wall Backfill Plate to bridge (6" diameter) weep hole Cut back of black plastic on sheet drain to match size of weep hole. Do not cut filter fabric. Footing Floor Slabs AMERDRAIN sheet drain can be used under the slab to help intercept ground water before it reaches the slab. Water can then be routed to a discharge pipe or sump. French, Trench & Cut-Off Drains AMERDRAIN sheet drain and AKWADRAIN strip drain may be used instead of, or in addition to, aggregate to intercept, collect and transport horizontal water flow. Embankments AMERDRAIN sheet drain may be used in embankments to prevent soil swelling or weakening from rain or ground water absorption. Horizontal, or a combination of horizontal and vertical drain, may be used. Landfill Caps & Underdrains AMERDRAIN sheet drain intercepts rain water in the landfill cap and routes it away from the landfill. Installing AMERDRAIN sheet drain under or on top of the landfill liner provides controlled exit of leachate. Lagging & Shoring Walls Where space is limited and valuable or where aggregate drainage would be difficult to install, AMERDRAIN sheet drain can provide drainage with its small space requirement and lightweight material. It can be attached directly to the wall for full coverage or vertical strips based on drainage needs. Parking & Plaza Decks AMERDRAIN sheet drain is a cost-effective alternative to aggregate for parking and plaza deck drainage. It is more efficient and easier to handle than installing a typical aggregate drainage system. AMERDRAIN sheet drain is quickly and easily installed, and collects and transports water more efficiently within a much more confined space. The use of AMERDRAIN sheet drain under grouted brick or pavers in driveways, prevent settlement and freeze-thaw problems caused by saturated sub-base materials. Wearing Surface Fabric Wrap Fasten (tie wrap) Weep Holes Double-acting Drain Athletic Fields, Golf Courses, Playgrounds, & Landscaping The high flow capacity of AMERDRAIN sheet drain and AKWADRAIN sheet drain makes it ideal for quick drainage of playing fields and golf courses where early use after rains is desired. 4 Drain Clamp Ring Waterproofing Structural Slab Vertical Wall

5 NEEDS... Shotcrete & Gunnite Walls AMERDRAIN sheet drain in strips or with full coverage can provide effective drainage for shotcreted walls. The formed core provides a good surface for adhesion of reinforced shotcrete or other construction materials. Pond & Channel Liners The installation of AMERDRAIN sheet drain under the channel liner prevents uplift due to hydrostatic pressure. The chance of structural failure, or leakage is also greatly reduced. Earth, Rock & Rolled Concrete Dams AMERDRAIN sheet drain may be used to prevent seepage at the toe of the dam or as a vertical cutoff wall in the structure. Slope stability during rapid draw down is also aided. Tunnels & Box Culverts Water can attack these structures from four directions: top, bottom and either side. AMERDRAIN sheet drain provides rapid removal of water to reduce hydrostatic pressure and to reduce leakage into the structure. Reinforced shotcrete can be applied directly to the sheet drain core. Chimney Drains Amerdrain sheet drain may be installed in vertical strips where full coverage is not required. Typical Applications for GreenRoofs, Roof Gardens & Planters Landscape architects use AMERDRAIN sheet drain as a lightweight replacement for aggregate drainage. The prefabricated drain takes only ¼ -1 (6-11mm) versus 4-6 (- mm) for gravel, thereby leaving more room for soil. Hauling gravel several floors up to a roof garden is avoided and lower roof loads are possible. The AWD AMERGREEN product line is specifically designed for this application.
