Manhole Grouting



Chemical Grout Stops Leaks in Manholes and other Structures

Chemical Grouting is a proven and economical way of stopping water and sand infiltration in Manholes and other structures such as catch basins and lift stations.

Williams Testing seals manholes and other type of structures such as catch basins and lift stations using Williams Testing’s Grout/Seal technology. Williams Testing’s grout technicians inject grout under pressure into the surrounding soil. A grout curtain behind the structure’s wall is formed resulting in an impermeable barrier for water to re-enter the structure.

Williams Testing uses Chemical Grouts manufactured by Avanti International.
