Cracked Foundation Repair with Steel Push Piers

clock January 16, 2012 04:19 by author
Steel Push Piers are the most popular form of foundation repair for settling homes. When installed by trained foundation repair contractors steel push piers will provide years of structural support.

Foundation Repair using Steel Push Piers

Foundation repair, steel push piers

One of the advantages of using push piers (resistance piers) for foundation repair is that they use quiet vibration free hydraulic equipment to  install the steel resistance piers. All of the installation equipment is highly portable and can be easily transported on the jobsite. After all of the steel push piers are installed and load tested, the structure can be immediately restored or lifted by transferring the load of the home to the piers. There's no time wasted, waiting for concrete to cure, and no soil to remove from the site. A measured factor of safety is verified, as the piers are 100% load tested to a force greater than the actual working load. This all means that you will get verified structural support for many years when you require steel push piers to be used on your home’s foundation.

Remember to always consult with an independent professional engineer before starting any structural foundation repairs and these repairs should only be performed by trained foundation repair contractors.

Steel Push Piers Installation

Below, the following steps the typical installation procedure for the largest selling Steel Push Piers:

1. Site survey: Pier placements are located around the structure and the location of underground utilities verified.

2. steel push piersExcavation: Small excavations or the entire perimeter is dug for access at each placement location. The space required at the foundation is usually about 3 feet square.

3. Prep of the foundation: This includes notching the concrete footing to place the push pier bracket under the stem wall, preparing the bearing area under the footing to a smooth and level condition, and adjusting the face of the stem wall to vertical at the point of bracket attachment.

4. Bracket Attachment: The steel resistance pier bracket is secured to the footing using anchor bolts. Attachment of the drive stand and the hydraulic cylinder that is used to force the pier pipe into the soil is mounted on the drive stand.

5. Push Pier Pipe Installation: The steel pier pipe is advanced into the soil using the structure as the reaction force with a 10,000 psi hydraulic pump and cylinder combination. The piers may be installed from outside or inside the structure. Pier installation continues until rock or suitable bearing-strata is encountered below the unstable soil near the surface.

6. Load Test: Every resistance pier is load tested by increasing the force on the pier to insure the rock or bearing-strata will support a load greater than needed to guarantee a factor of safety. Typically an engineer will determine the load of the structure and the desired factor of safety before the load tests are performed.

7. cracked foundation repairPreps for Restoration: Once all push piers have been installed, load tested, and the installation data at each placement recorded; lifting head assemblies and hydraulic lifting rams are placed on the steel piers. The lifting cylinders are connected with one or more manifolds and operated using a hydraulic pump.

8. Restoration: Under careful supervision, the load is transferred from the existing failing strata under the foundation, to the load tested piers. The structure can be transferred gently and evenly lifted to as close to the original elevation or to the recommendation of the engineer. The nuts at the pier caps are secured at each placement and the lifting equipment is removed.

9. Clean Up: The soil that was excavated at each steel push pier placement is now replaced and compacted. The site is left clean and neat.
