For this project, our team successfully waterproofed a concrete block (CMU) wall using Xypex’s advanced crystalline technology. After carefully preparing the surface and repairing any cracks or weak points, we applied a two-layer system designed to penetrate and permanently seal the wall from water intrusion—even from the negative side. The result is a clean, durable finish that provides long-term protection and reinforces the integrity of the structure. This solution is ideal for high-moisture environments where reliability and longevity are critical.
