Hydraulic Driven Steel Piers
We offer a variety of pier to match the specific application needed to repair your foundation. Our most common pier used is the hydraulically driven steel pier. This pier is used for residential and light commercial use. The piers are 12" wide and will go under the footing. We trim the footing for proper positioning of the pier. This is an important procedure in pier installation. If the footings are not square at the bottom, we will grout this area with high strength grout. The pier is placed and bolted to the footing with 5/8" anchor bolts to hold the pier in the proper position. The pipe that we drive is 3" in diameter with .250 wall. Our piers are installed to bedrock or equal load bearing strata. In the Tulsa area this can be 10-60 feet in depth.
Drilled Piers
Sometimes thin layers of shallow rock are encountered and can stop the pier from reaching it's proper depth. In those areas, we use a special drill machine to drill through the layers before we install our pipe. This will insure that we are installing our pier to bedrock or equal load bearing strata.
Exterior Helical Piers
We use exterior helical piers for special residential application, such as structures that are light weight or in need of column repair. In commerical applications, in which the structures are normally heavier, we can increase the bar size to withstand the weight of the structure. We have used these piers for swimming pools, small bridge repair, and gymnasiums.
Interior Piers
Interior piers are made with a 6" helical to support the floor slab. The piers are placed approximately 5' on center. The helical is screwed to the proper depth and then the lifting assembly is attached. The piers are lifted in small increments until the proper lift is achieved. This type of slab pier does not use the weight of the slab to install, allowing for less cracking and stress on the slab. We have a licensed plumber perform a plumbing pressure test before and after slab piering.
Drainage
Proper drainage can play an important role in foundation stability. We provide the following drainage solutions:
French Drains: Handles sub surface water. (Moisture in the air ducts can be a sub surface water problem).
Drainage Swales: (Regrading) This will allow for surface water to be redirected away from the house foundation and channeled to a point where it does not pond by means of removing soil and resodding.
Drainage Boxes/Catch Basins/Down Spouts: Installed using solid drain pipe to carry excess water away from the home.
We also waterproof basement walls and provide proper drainage systems before backfilling.
In our shop we manufacture the products that we use. We keep strict guidelines for quality control of all the products that we produce. The structural repair work is so specialized because of varying field conditions that we can create or modify any of our products in our shop or on your site as needed.
