Drilled Caissons for Deep Foundations

When are caissons required?

Typically caissons are used when shallower foundations such as strip footings or spread footings cannot be constructed economically or safely due to poor soil conditions such as high water tables or hydrocarbon impacted soils. Or when additional uplift resistance is required.

Caisson foundations can be constructed to transfer compressive loads to competent bedrock or soils. Additional capacity can be achieved in both compression and tension by drilling sockets in the bedrock.

At Brewster Well Drilling, we use specialty equipment and large diameter down hole hammers capable of boring large diameter holes. Steel casing is used to hold back lose material or caving soils that can be removed after the concrete is placed or left in place depending on site conditions and design requirements. Concrete is typically pumped in place using a four inch tremmie pipe to avoid segregation of concrete materials which could occur if the concrete is allowed to free-fall.

Installing deep foundations can be a dangerous process. Brewster Well Drilling recognizes the importance of accident prevention and employees are trained on the equipment they are using, in proper storage and handling of construction materials, and to never compromise the health and safety of other employees, subcontractors, pedestrians or the communities near where we work.
