e.drain has been specifically designed to meet the drainage and protection requirements of below grade waterproofing applications. E.Series utilizes e.drain In applications for over excavated below grade foundation walls to effectively eliminate the buildup of nuisance water, provide another layer of waterproofing redundancy, and provide protection during backfill. e.drain is also applied to shoring as a base course for e.spray. When concrete is applied, the e.drain and e.spray become integrated into the below grade foundation walls, forming a uniform composite system that directs water away and provides a seamless waterproofing membrane. e.drain features a lightweight three-dimensional, highly flexible high density polyethylene (HDPE) core and a polypropylene geotextile filter fabric. The filter fabric is bonded to the dimples of the HDPE core.
