We have successfully estimated, managed and constructed over $200 Million in ground improvement, foundation and shoring projects in Washington, Oregon, Idaho, California, and Hawaii. We service a variety of industries including:

Rigid Inclusions

Rigid inclusions consist of grout columns installed using displacement auger or vibrated tooling. Rigid inclusions consist of grout columns installed using displacement auger or vibrated tooling. The columns are typically installed in an array to provide support for footings, mats, or embankments.

Due to the relative small column diameter and low replacement ratio, the surrounding soils typically have minimal densification or improvement. A gravel load transfer platform is commonly used above the rigid inclusion head to distribute stresses more broadly to the supported structure. The geotechnical engineering mechanics of rigid inclusion design are similar to those of deep foundation systems, but they are typically only lightly- or un-reinforced and are not structurally connected to the above-grade structure.

The popularity of rigid inclusions is increasing in the Western U.S., where many urban areas are subject to moderate to high seismic hazard levels.
