“Howie, you're a man of your word, a rare thing today.
Your men worked hard and left the worksite nice and clean.”
At Bruecher Foundation, we use the pressed piling method of foundation repair for slab foundations.
We believe that the pressed piling is the all-around best repair method for slab foundations. Contrary to conventional foundation repair systems, pressed pilings:
These three factors enable shorter install times and lower costs.
First, our crew determines the locations of the pilings. Plants are temporarily removed from these locations, and a small 3-foot hole is dug at each spot. Next, the 6-inch diameter concrete cylinders are driven one-by-one into the ground by a hydraulic jack. This forms the pressed piling column, and is usually pressed to depth of about 15-30 feet. The depth of the piling depends on the site's soil conditions: pilings are pressed to the point of refusal, since that is the point at which the ground is solid enough to firmly support the structure.
After the piling columns are in place, a pile cap is placed on top of each piling. The structure is now jacked up at each piling location until the structure is completely level. Steel shims are placed at each piling location to maintain the leveling.
Cleanup now begins, with the access holes filled in, and plants returned to their original locations. Since the pressed piling system doesn't require us to remove large amounts of dirt, there is little debris that needs to be removed from the premise. In most cases, there is little permanent visible exterior evidence that foundation repair even took place.
Yes. Pressed pilings have been extensively tested, and are approved for use in the City of Austin Texas. The pressed piling system has also been approved by the U.S. Department of Housing and Urban Development, as per HUD program ExTech 233. Pressed Pilings are also Federal Housing Administration approved.
The system is designed to test all components to the point of failure.
If the soil won't support the structure, the piling will press through it. Should an individual piling be weak, it will crush and a new one put in its place.
For pier and beam structures, we will inspect the current structure's piers. If only jacking and leveling is required, we simply jack the structure up at each pier location and place shims to level the structure.
If the current piers are rotted or otherwise unstable, they will need to be replaced. We will first put shoring in place to temporarily stabilize the structure. We will then dig a 2x2x2 foot hole for the new pier locations. Any rotten wood or beams will be replaced at this point.
After the concrete footings have set, the structure will be jacked and leveled and the plinth—the top of the pier—will be poured onto the footings. After the pier has set, the new piers will be poured right to the bottom of the beams. No shimming will be needed. The new foundation is now structurally stable on its own, and the temporary shoring is removed.
We now completely clean up any debris from the site. If any plants were removed, we now replant them.
We install small retaining walls using railroad ties, Allan blocks, or some similar type of engineered block.
We perform drainage corrections, which often are the cause of foundation problems. We install French drains and surface drains.
