AWD prefabricated drains provide a specific, engineered response to a particular drainage problem - how to collect and re-direct water away from a structure or site.
AWD manufactures a full line of products to address drainage requirements for a broad range of construction applications. Our prefabricated drains consist of formed three dimensional polymeric cores that are combined with a geotextile filter fabric. The core offers strength to withstand soil pressure and provides a secure flow channel for collected water. The filter fabric retains soil particles while allowing water to freely enter the drainage core. AWD's sheet, strip, combination and wick drains provide a specific engineered response to your drainage problem.
Unlike pipe and stone systems, AWD products are manufactured to meet specific physical and mechanical properties that are verified by independent testing laboratories per ASTM standards, ensuring your project will "flow" according to plan. Critical design considerations typically include three basic physical properties - water flow rate, core compressive strength and the ability of the fabric to filter soil particles.
