New Construction Helical Pile Systems

Helical pile systems are an extremely versatile new construction deep foundation alternative, used within grade beams and pile caps supporting residential column and wall loads. 

Helical piles can be installed with hand-held equipment, mini-excavators, skid steers, backhoes, or trackhoes, so the installation equipment can be sized for the project.

Helical piles are a vibration-free deep foundation system. The piles are mechanically advanced ("screwed") into the ground to appropriate depths and capacities.

New construction caps are then attached with the top of the cap being a minimum of 3 inches into the grade beam or pile cap.

Helical piles can permanently stabilize sinking or settling foundations. L-shaped steel foundation brackets are connected to the tops of the helical piles and installed against the footing.

The weight of the existing structure is then carefully transferred from the unstable soils, through the piles, to competent soil or bedrock.

Advantages of Helical Piles

Helical piles present many advantages including:

• Helix blade configuration selected to achieve design depth and capacity

• Can be installed in areas of limited or tight access

• Installs quickly

• Installation does not generate spoils

• Vibration-free installation (unlike driven piles)

• Concrete can be poured immediately following pile installation

• All helical piles are hot-dip galvanized for added corrosion protection

• Cost-competitive compared to other deep foundation alternatives (auger-cast).
