Proofex Engage

Proofex Engage is a pre-applied membrane which mechanically bonds to poured concrete.

This unique patented waterproof membrane system incorporates a cell mesh, bonded to a blended polyethylene/polypropylene membrane, which allows poured concrete to interlock, forming a tenacious mechanical bond.

Proofex Engage provides water, water vapor and gas protection to water excluding structures and protects concrete from aggressive ground salts, chemicals, and hydrocarbons.

Proofex Engage is supplied with a self-adhesive selvage along one side of the roll to provide sealed laps and a comprehensive range of auxiliary products to simplify the application process.
