Water Control Technology™ is a masonry wall system with superior resistance to moisture penetration.

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. 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 units feature integral drainage zones that direct moisture to the wall’s drainage system. No special installation techniques required and cost-effectiveness is assured. WCT units are suitable for corners and ends for a complete system and all units have integral water repellent in their mix design.

WCT™ is just one of the many industry leading innovations developed by CPG to enhance the performance of your building.

Advantages:

  • WCT UNITS MEET OR EXCEED ASTM C90.
  • PERFECT FOR BOTH SINGLE OR MULTI-WYTHE WALLS.
  • OFFERED IN A WIDE VARIETY OF SHAPES AND SIZES, RANGING FROM: SPEC-BLOCK™ (PRECISION GRAY CMU), SPEC-BRIK® (BRICK APPEARANCE) AND SPEC-SPLIT™ (SPLIT FACE CMU)

WCT Spray Bar Test Video

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.
