Sika® Drain Strip


Sika® Drain Strip is a 1” thick polypropylene, high flow, dimpled drainage core wrapped and bonded with a non-woven filter fabric. Water passes into the drainage core to relieve hydrostatic pressure while backfilled soil, sand, and debris are retained by the filter fabric. Collected water is then conveyed to a collection system through Sika® Drain Strip fittings such as End Outlets and Side Outlets.

  • Reduces or eliminates hydrostatic pressure
