Spec-Thermal Technical Documents

Water Control Technology™ (WCT) is based on preserving the superior performance characteristics of concrete block while adding features that improve the ability of masonry wall assemblies to resist moisture penetration. We made subtle changes to the top surfaces of each WCT block’s webs to discourage water from crossing to the interior face shell.
