Screw Shaft Push Helical Piers

What Are They?

Helical Piers are heavy, round, steel-shaft ‘screws’ that are designed with cork-screw-like plates that are attached to the shaft, called helicals. Like a screw that is driven into a piece of wood, these large piers spin with tremendous force and embed way down deep, directly into the soil. Utilizing such compressive force, helical piers are expertly designed to permanently stabilize or shore up homes and commercial buildings.

Driven by hydraulic power, these piers slowly spin downward into the ground. This immense rotating force of the pier tightens the structure to the sub terrain below, so that eventually the home or building can become permanently affixed, strong and secure.

How Do They Work?

They are driven into the soil like a corkscrew, to depths below the frost line, penetrating deep through the layers, until they hit hard soil which is solid and tightly bound. The pier is screwed into the soil hydraulically, until the desired torque or depth (capacity) for the structure is achieved. It is then spaced at the most optimum intervals, in order to evenly spread the load of the structure. Brackets attached to the piers are then affixed to the foundation wall base, and the weight of the structure is transferred to the piers. Being embedded deep into the ground, the building can now stabilize, being permanently ‘screwed in’ to the firm soil, far beneath the structure.

Advantages of helical piers

If installed properly can lift a home structure back to its original position

No foundation replacement necessary
Suitable for both heavy and light loads
Can go as deep as needed
