ProElast® System

ProElast® System

The reliable ProElast® System is an external sealing system for working joints and crack control sections which is capable of resisting high water pressure.

The proven ProElast® System is an easy-to-use, 2-part sealing system. It consists of the robust ProElast® EPDM foil and highly adhesive InnoElast® adhesive and sealant. The ProElast® System is an external strip-shaped sealant for construction and crack control joints. In addition to high waterproofing, the system is highly UV and weather resistant.

The ProElast® System benefits from the unique adhesive and handling properties of InnoElast®. The system is capable of processing starting at -3ºC component temperature and on matte-moist ground.
