Soil Stabilization by permeation grouting and compression grouting

Permeation grouting is a method where the resin injected into the ground permeates the soil before it reacts resulting in an underground matrix that is solid, load bearing and impermeable to water. Adjustment of the catalyst component allows control of the material set time.

Inducon Corporation uses this type of injection to stop ground water infiltration in underground structures and in some particular “curtain wall” applications where sheet pile shoring is not possible or feasible.

The Compaction grouting process utilizes chemical grouts whose properties do not allow them to mix with the soil but instead displace the surrounding soil as the volume increases up to twenty times as it goes through its curing process. Typically grout is pumped through vertical pipes which are arranged on a grid thereby compacting the soil in place.

One example of Inducon Corporation’s use of this method is to increase compaction of loose fill inside a foundation wall under a settling slab.
