H&B MGS Mortar Grout Screen - 100ft Roll
The H&B MGS Mortar Grout Screen is a high-performance, non-metallic screen used in masonry construction to isolate grout flow and improve anchor bonding. Designed for use in reinforced concrete block walls, it helps direct grout only where needed—typically around rebar or other reinforcement—while preventing unnecessary filling of adjacent hollow cores.
Fabricated from 1/4 in. square monofilament polypropylene mesh, this screen offers high tensile and burst strength while remaining thin enough not to interfere with mortar bond. It is especially useful in hollow block construction where proper placement of grout is essential for both performance and cost control. The screen also enhances the effectiveness of masonry anchor installation by preventing grout migration into anchor zones.
The MGS is available in multiple standard widths (4 in., 6 in., 8 in., 10 in.), making it adaptable to different block sizes and reinforcement layouts. It’s a smart solution for contractors looking to maintain structural integrity and save on grout while ensuring code-compliant reinforcement practices.
