PREVENT CRACKING AND DEGRADING BY RETRACTION OF CEMENT UNDERLAYERS. A compression layer that has not yet fully set contains a high degree of residual moisture, which during the drying process will trigger a retraction, with the consequent loss of volume.
PREVENT CRACKING AND DEGRADING BY THERMAL EXPANSION OF THE STRUCTURE. Temperature changes directly affect the different underlayers and materials, continuously expanding and retracting. These movements are transmitted directly between the compression layer and the covering.
In both cases, the cover materials are directly affected, with the formation of cracks in the joints and detachment. The DRY80 and DRY120 POOL, membranes, because they’re composed of a double layer of polyolefins, can stop movements between the compression layer and the covering, preventing possible cracks in the joints and the potential detachment of the top covering itself (crack bridging).
