DELTA®-THENE 40

The Problem

Even if a below-grade foundation system has drainage capabilities, it cannot be complete without a waterproofing membrane. The waterproofing membrane protects the foundation from water intrusion, and therefore lowers humidity levels. Certain high-performance barriers also protect against radon, heightening the air quality and ensuring occupant longevity.  

The Solution

DELTA®-THENE 40 is a full-coverage, below grade, self-adhering, waterproofing barrier, suitable for light-duty commercial application.

DELTA®-THENE 40 is ideally suited for use behind DELTA®-DRAIN drainage composites. Its highly aggressive adhesive allows reliable waterproofing coverage. When used in combination with a drainage system, DELTA®-THENE 40 provides waterproofing security for a reliable waterproofing system.
