In some below-grade waterproofing applications, DELTA®-THENE 40 may not meet all of your requirements. When a heavier duty waterproofing barrier is needed, look to DELTA®-THENE 60.
A below-grade foundation system cannot be complete without the correct waterproofing membrane. It protects the foundation from water and vapor intrusion, lowering humidity levels. Certain high-performance barriers also protect against radon, heightening the air quality and ensuring occupant longevity.
