Low Mobility (Compaction) Grouting (LMG) is a ground improvement technique offered by Wagman.

Wagman Low Mobility (Compaction) Grouting
Low Mobility Grouting

With this process, a low-slump, cementitious material (grout) is injected under high pressure. The material is designed to not travel far from the injection point, but rather densify and displace soft or loose soils. It is also used to fill voids, seal openings, and seal top of rock surfaces. LMG is particularly useful in karst geology, to fix sinkholes, and sometimes in mine subsidence.

LMG is typically installed on a grid pattern, in a bottom-up sequence. Grout casing is installed to the design depth. Then as grout is injected, casing is pulled in stages until the entire height is treated. It is often specified as pre-treatment of an area prior to construction. Wagman can help design the grid spacing, grout injection termination criteria, and mix design based on the subsurface conditions and the requirements of the proposed construction.
