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)
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.
