GM Grout Range

Pozament General Purpose Construction Grout is a versatile range of flowing general-purpose grouts designed for applications where a high sulphate resistance is required including annulus grouting, void filling, piling and ground remediation. They meet the requirements set out in BS 8500-1 to achieve a sulphate resistance class of DC4.

Why use Pozament GM Grout Range
