Caissons

What Are Caissons?

Caissons are large diameter holes that are dug through poor soil into inadequate bearing soil. This allows your foundation to rest on the deeper soil and bypass the problem soil. This is a common repair on hillsides and cut and fill construction areas.

How Do We Use Caissons

A drill rig is brought in and holes dug to a depth as determined by engineering and soils reports. Hole depth can range from just a few feet to 20′ and beyond. Caissons are filled with concrete, attached to the grade beam which your structure is then resting on.

Unlimited Drilling & Foundations Inc. specializes in all aspects of foundation repair.
