ECODRAIN-E has been specifically designed to meet the drainage and protection requirements in below-grade waterproofing applications. ECODRAIN-E drainage composites effectively eliminate hydrostatic pressure against below-grade structures and aid in de-watering saturated soil by collecting and conveying groundwater to a drain pipe for discharge while protecting the waterproofing membrane.
Composition:
ECODRAIN-E features a lightweight three-dimensional, highly flexible HDPE core and a polypropylene filter fabric. The filter fabric is heat bonded to the dimples of the HDPE core. This bonding prevents backfill from pushing fabric into the flow channels and reducing waterflow. The filter fabric allows water to pass freely into the molded drain core where gravity draws the water through the flow channels to the discharge system, while preventing soil particles from entering and clogging the core structure and discharge pipe, significantly increasing the effectiveness and service life of the drain system.
Benefits:
· High density polyethylene core provides: (1) resistance to chemical attack from soil, (2) secondary waterproofing barrier, (3) thermal resistance, and (4) flexibility for easy detailing of corners.
· Heat-bonded geotextile will not delaminate from core in warm temperatures, as adhesive bonded materials do. Convex (rounded) dimple design reduces stress on protected waterproofing membrane or insulationboard from backfill pressure while eliminating hydrostatic water pressure.
· Variable widths (6.6' and 8') provide minimal overlapping seams and cost effective installation.
Limitations:
· Should not be exposed to long duration of UV.
· Application depth of 30 ft.
