New Masonry Wall System with Superior Resistance to Moisture Penetration
Why try to improve one of the most trusted construction materials available? Water Control Technology™ 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. Corners and ends can use the WCT drainage zones without compromising aesthetics or performance.
These innovations are accomplished with a block that is fully compliant with the concrete masonry unit standard, ASTM C90.

WCT: Innovative Masonry Design
- WCT units feature integral drainage zones that direct moisture to the wall’s drainage system.
- No special installation techniques required--cost-effectiveness is assured.
- WCT units are suitable for corners and ends for a complete system.
- All units have integral water repellent in their mix design.
In the video below, watch as WCT units were spray bar tested with no mortar (just gaps) alongside a traditional block design with a water flow rate equivalent to 180” of rain per hour for a half hour and then at a rate of 30” of rain for an additional 24 hours. Result: The traditional block began to show moisture penetration to the interior surface after 11 seconds. The WCT block completed the 24 hour test without any evident moisture penetration to the interior surface of the wall.
