Permeation grouting is a process that injects single-component polyurethane grout into the ground. The polyurethane grout absorbs into the soil, expands and solidifies. Permeation grouting is applied through thin metal pipes that can be driven into the ground at depths of four or five feet. If additional depth is needed, other methods are used to inject the grout.
Permeation grouting is often used when there is uncontrolled water drainage, such as bulkheads or seawalls. The grout itself is moisture activated so it is ideal for wet environments.
Compaction grouting, also called deep injection, is a process that injects plural component polyurethane grout into the ground. Unlike permeation grouting, compaction grouting does not absorb into the soil. Since it doesn’t absorb into the soil, compaction grouting is best used under foundations, structures and concrete slabs with a known compaction problem underneath them. Compaction grouting is also spot injected to stop leaks behind basement walls and other areas with a targeted leak.
Compaction grouting is an ideal solution where loss of support has occurred but settling is not significant but is not to the point of needing to be raised substantially. Compaction grouting can be used to re-support pole barn/buildings, homes, outbuildings, and other structures. If your structure has settled to a significant extent and needs to be raised substantially, we can assist you with one of our foundation repair services.
