What should be done to the surface prior to membrane attachment to foundation walls?

The proper preparation of the surface prior to membrane attachment to foundation walls is critical for ensuring the effectiveness of the radon mitigation system. Cleaning and preparing the surface is essential because any debris, dirt, or moisture can compromise the adhesion of the membrane, potentially leading to leaks or failures in the radon barrier. A clean surface allows for a more uniform and secure bond between the membrane and the foundation wall, maximizing the system's ability to reduce radon infiltration.

By ensuring the surface is properly prepared, including removal of any contaminants or imperfections, the installation becomes more effective, thus reinforcing the overall integrity and reliability of the radon mitigation system.
