Weather-resistant barriers (WRBs), also known as building wraps or housewraps, are one of the best building materials for controlling water, either through blocking rain from entering the wall cavity, allowing moisture vapor to move and escape the wall cavity, or draining bulk water away from the wall assembly.
With the variety of cladding materials available today, and designers’ penchants to combine styles and textures, it is essential to specify building envelope controls that are compatible with multiple cladding types. This balancing act between aesthetic preferences and air and moisture management is where gypsum-integrated water-resistive barrier-air barrier (WRB-AB) sheathings shine.
The major cause of foundation-related problems is water. Hence Waterproofing systems are very critical to keeping foundations dry. Like air control above grade, it is important to consider water control below grade as a system solution, and not just as a single component.
For projects with tight timeframes and stringent performance requirements, PMMA/PUMA technology coatings and membranes are appealing due to its ultra-fast cure time, even in extreme weather conditions, and long-term durability.
Below-grade construction with shotcrete is gaining popularity across the country. The trend of using shotcrete instead of conventional cast-in-place (CIP) concrete can be attributed to the lower construction cost and time saved by not having to place and remove formwork.
