Trifusion’s Advanced Hydraulic Pier System

advanced_hydraulic-piering_tulsaTrifusion’s Advanced Hydraulic Pier System consists of pre-cast concrete piles that are hydraulically pressed into the ground until the force is so great that the pile cannot be driven into the ground any further. Each piling is designed to support up to five times the weight of the structure. Traditional piering methods used by many companies in surrounding areas might stop at a pre-determined depth of 4 to 8 feet, this method allows Trifusion to go into the ground at a designed depth to best support your foundation. This system has been tested by engineers and accepted as one of the most advanced hydraulic piering systems currently available.

Our crew will mark off the location of each proposed piling and carefully remove everything in the immediate area. Plywood (or another material) is placed near the hole that is to be dug, so that any soil excavated from the hole can be recovered after the job is completed. After the area adjacent to the exterior grade beam is cleared, a hole is dug approximately 4′ x 4′ wide to gain clearance under the beam, and 3 1/2′ deep to allow placement of the specially designed hydraulic pile driver used to force the concrete sections into the ground. The piling segments are 12′′ long and 6′′ in diameter and made of 8000 psi concrete. They are placed one on top of the other and forced down into the ground until they meet the point of refusal. Once the pilings cannot be driven any further, a gauge on the jack determines how many pounds per square inch is being applied to the pilings, and if that measurement is sufficient, the piling drive is complete.

After the piers are in place, the perimeter beam will be leveled and lifted as close to its original level as possible. Solid concrete blocks and steel shims are then used to fill the void and secure the area under the load bearing beam. Soil is them placed and compacted back under the load bearing beam. Anything removed from the dig area will be relocated to its original position. Despite all the displacement, it is hard to see where any work has taken place after the thorough cleanup. The only exception is when concrete is located where a piling needed to be installed. If this is the case, the concrete is broken out and removed. The hole is dug and the press pile is driven as explained previously. Due to the aging process, the concrete used to patch holes made through existing concrete may be a different color than the original concrete.
