VersiDrain® EC is a low profile composite drainage sheet used in conjunction with Bitulen® SK374 and VersiTape® F100 in the VersiDrain® Waterproofing System.
Designed for use on thin-bed cement mortar such as those in stairs, the System mitigates efflorescence by creating a separation gap between the finish layers and the base structure. This relieves entrapped moisture within the cement mortar.

VersiDrain® Waterproofing System is a tailored solution for efflorescence mitigation on surfaces such as stairs. Even with the many stair edges and corners, this system can be easily integrated and installed. Click here for the brochure.
1. Bitulen® SK374 DUO
Self-adhesive, cold-applied 1.5 mm thick preformed waterproofing
membrane made from cross-laminated SBS modified bitumen.
2. VersiDrain® EC
Low profile composite HDPE drainage sheet that enables entrapped
water within the floor layers to be drained efficiently for efflorescence
mitigation.
