Foundation Underpinning & Piering: Helical Piers & Resistance Piers

Underpinning, Piles & Piers

The most effective way to help reverse the signs of a sinking foundation is to use a process called “underpinning,” “piering,” “pier underpinning,” or even “piling.”

There are many types of piering methods available from professional foundation repair contractors. However, the only true and effective solutions are those that transfer the weight of the structure or your home to more stable soil than the soil it is currently resting on.

Helical Piers

Helical Piers contain helices, or helical flights, that serve as end-bearing plates for the weight of the home. These flights are welded to a central steel shaft. The helical shaft essentially acts as a screw that is rotated into the soil.

When Helical Piers are used, the helices provide a large amount of surface area to resist or bear the weight of your home. Helical Piles are very effective in deeper soils where reaching bedrock is not possible. The helical flights will produce a force that translates into how much weight the entire pile or pier can carry.

Why Intech Anchoring Systems Helical Piers?

Underpinning and Helical Pier Anchor systems are used to transfer load weight to bearing plates located in stable soil. This patented system brings an economical solution to underpinning systems for existing foundations. Fast, predictable, and measurable are just three advantages of this building code evaluated and accepted method perfected by Intech Anchoring Systems.

Helical Pier Installation

Upon receipt of the plan of repair from a qualified design group or individual, the certified installer proceeds with the repair. One of the best investments you can make is to get a soil boring on your property. This will enable the designer to determine what type of anchor and to what depth it must go to reach stable soil.

The installer will usually excavate a hole at each anchor location wide and deep enough to place a bracket under the foundation. A rotary installing machine installs the leading section of the anchor with the proper number and size of helices. Extensions are added until the appropriate depth is reached and the predetermined torque is achieved. At the point in which the bracket is attached, the load is transferred to the anchor, stabilizing the building and allowing for lift, as according to the plan of repair.
