Installation Guideline: Sheet Drain

Description

Prefabricated drainage composite designed to enhance waterproofing / damp-proofing membrane by quickly channeling water down to the collection pipe and protecting the membrane during backfilling.

Installation Procedures

1. Place the 1st course of drainboard with the fabric facing the soil, dimples pointed away from the wall.
2. Fold the bottom edge of the fabric and tuck behind the core, keeping soils out of the core.
3. Attach the drainboard panel either with mechanical fasteners or adhesives to hold in place until completely backfilled. Check with the waterproofing manufacturer for approved adhesives compatible with their membrane or recommended methods.
4. 2nd course is placed with the core butted to the lower course overlapping the fabric using the "shingle" method. Secure fabric with duct tape.
5. The top course should be terminated by tucking the fabric flap over the top of the core.
6. Backfill should be placed immediately and cover at least 6 inches above the top course of drainboard.

Notes

1. It is recommended that you consult with your waterproofing membrane contractor and/or manufacturer to obtain installation guidelines pertaining to their products.
2. Rolls can be installed horizontally or vertically along the footer. When installing horizontally, begin at the bottom of the wall or foundation.
