Identifying the Need for Foundation Piering

Foundation settlement happens when the soil beneath your home expands and contracts, causing shifting. This often results in foundation cracks and other problems. While cracks in your foundation might not be a sign of a major problem, there are other symptoms to look for when deciding whether it's time to call a professional. These signs include:

  • Horizontal or vertical foundation cracks
  • Tilting chimney
  • Sticking windows and doors
  • Cracks above window frames
  • Cracking/sinking slab floors

All of our foundation pier systems can help stop foundation settlement and sinking and prevent these problems from occurring in the future.

What is Foundation Underpinning?

Foundation underpinning is a solution used to repair weakened foundations or increase foundation depth. Underpinning extends the foundation so that it rests on more supportive soil stratum or distributes the load across a greater area. There are several types of underpinning methods to suit different kinds of repair projects. Foundation Repair of CA uses helical piers for deep foundation underpinning, as well as push piers to permanently stabilize the foundation.

Foundation Helical Pier System

A helical pier owes its name to the helical plates welded to the pier shaft. These plates help to pull the pier into the soil during installation and provide anchoring strength as the weight of the foundation or structural element is transferred to the pier.

Helical piers have a great deal of versatility for stabilizing and restoring foundations and masonry elements.

Advantages Of Supportworks Helical Piers:

  • Year-Round Installation
  • Fast, Effective Installation
  • Stabilize Light Structures Like Decks Or Concrete Stairs
  • Can Help Lift Settled Foundations Back To Original Level
  • 25-Year Manufacturer's Warranty

Slab Pier System

Slab piers are push piers designed specifically to stabilize and (in some cases) raise slabs that have settled. This type of pier is driven into the soil in the settlement area, deep enough to connect the slab to stable, load-bearing soil or bedrock.

A specially designed bracket connects the top of the pier to the underside of the slab, to stabilize and/or raise the slab back to its original position.

Advantages Of Supportworks Slab Piers:

  • Can extend to great depths to contact stable soil or bedrock
  • Non-destructive repair requiring minimal excavation
  • Completely hidden after installation holes are filled
  • Can help lift a settled slab in addition to stabilizing it, in some cases
