Methods and Materials of Foundation Repair


Each home is different, so each repair job is customized to fit the specific project.

Foundation Leveling

First, we stabilize the sinking portions of your foundation by driving steel piers (also known as piles) into the load-bearing soils beneath your home. Once these piers are load bearing, we attach them to heavy duty brackets under your foundation footer, then jack that portion of your home back to its level state.

Basement Wall Repair

Foundation problems often bring about basement wall damage where the wall bows inward. Depending on how extensive the damage, we may recommend a combination of a few options. Using industrial-strength materials, we stop the wall from further inward movement.

Foundation Repair With Helical and Push Piers

Helical piers have curved steel plates welded onto the shaft of the steel pole, essentially making it a giant screw. The helical plates transfer the weight of your home to the pier. They anchor the structure and provide strength as they are pulled through the soil during installation. Helical piers are the best choice for softer surface soils.

Push piers are sometimes necessary when working with denser soil, where helicals cannot screw down easily. Our St. Louis customers know what that’s like due to the high clay composition of their soil. These piers support your home as helical piers do, but they are driven into the ground using a hydraulic ram, rather than screwed. Push piers are less versatile than helical piers.

Our foundation experts will work with you and your soil to come up with the best solution for your home and budget.

How Foundation Repair Piers are Installed

Our crews show up on the date scheduled and begin repairs.

  1. At each pier location, they will excavate to expose the portion of the foundation that will get anchored.
  2. Steel L-shaped brackets are placed under the footing of the foundation.
  3. Piers are then driven into the ground until they reach appropriate load-bearing specifications.
  4. The weight of your structure is shifted from the unstable soils to the piers using hydraulic jacks.
  5. The crew attempts maximum recovery of any wall-shifting.
  6. The excavated soil is filled back in to cover the brackets/piers.

While it’s typical for cracks to close, it’s not guaranteed.  The goal is to stabilize the foundation; cosmetic issues are secondary to a stable foundation.

Kent Home Services uses the latest piering technology to restore your sinking or cracked foundation to a level, more waterproof state.

Basement Wall and Retaining Wall Repair

While piles are typically installed to prevent or stop vertical foundation movement, helical tie backs are used to prevent or stop lateral movement.

Kent Home Services utilizes the strength and stability of steel piers by installing them horizontally (though angled downward to achieve greater torque).  Steel plates are fastened to the wall at a given distance apart to reinforce and stabilize the wall.

Structural Support Beams

This is a specialized steel support system called The Force which works to straighten your bowing basement wall. The support beam is tension spring loaded, constantly applying 1,000 pounds of pressure to the inside of your wall to compensate for the pressure coming from outside. This reinforcement straightens and supports your basement wall.

The beams are bolted into the concrete floor and to the frame of the floor above. The beam pushes the inwardly bowed wall back to its straight position.

Reinforcement Strips

We use a patented carbon fiber solution called The Reinforcer. This is the most unobtrusive and efficient way to correct your bowing walls. The Reinforcer is made of material tested at 10 times the strength of steel.

These low profile brackets pull in vertically on your bowing basement wall to straighten it and work counter to the incoming lateral pressures.
