Solving Structural Problems of Foundation Settling

Solving Structural Problems

Common indications of foundation settling include cracked or bowing walls, sloping floors and a leaning chimney.

Any of these problems, left unchecked, can result in significant structural issues. Fortunately, foundation support products can correct the problem, stabilizing your home to restore its structural integrity.

Several types of support systems are available. Here, we take a look at three of the most common used to repair foundation settling and the resulting damage.

Installing Resistance Piers to Correct Foundation Settling

Resistance piers are frequently installed to transfer the weight of a home to dense soils that are capable of providing enough support.

Also called push piers or micro piles, resistance piers are heavy duty steel tubes that are hydraulically driven deep through the foundation below the home until they reach load-bearing soil. The piers are pushed through steel brackets connecting the piers to the foundation.

After all of the necessary push piers have been installed, the home is stabilized and secured in a level position.

The unstable soil that caused foundation settling is no longer responsible for supporting the weight, as the piers are now handling that job. Resistance piers are designed to handle the heaviest structural loads.

Fixing Foundation Settling with Helical Piers

Helical piers, on the other hand, are often chosen for lighter structures experiencing foundation settlement problems. Foundation repair contractors may also use these supports when specific soil conditions are identified, because installation can achieved at a precise depth.

Like resistance piers, helical piers are strong, heavyweight steel tubes. In this application, the tubes are fitted with plates that make them look like screws, that act to pull the tube down into the ground.

These piers are not pushed hydraulically through the soil. Instead they are mechanically turned until they reach the proper depth. At this point, steel brackets are attached to secure the piers to the foundation. The helical pier system then takes on the weight of the home, providing support and making it level.

Repairing Foundation Settling Problems with Tieback Anchors

Foundation settling can cause basement and retaining walls to buckle or crack. Tieback anchors, or helical tiebacks, are horizontal steel rods that can fix this structural problem by reinforcing the walls and providing stability. They can also straighten bowed walls.

To support walls with tiebacks, soil on the exterior may first be removed to relieve pressure. Next, small holes in the interior walls are drilled and one end of each helical tieback is secured to the wall. The anchors are then screwed into the soil and tension is applied to strengthen and straighten the wall.

Foundation settlement should never be ignored, as the damage will only get worse over time.
