Our warrantied solution for permanently repairing your foundation issue includes the following steps:
To prevent future expansion damage to your home from street creep, we first cut new expansion joints in the driveway. New expansion joints will provide additional expansion and contraction space to end the street creep cycle. After cutting the joints, all excess concrete and debris will be cleared away.
All expansion joints are filled with a resilient foam backer rod that will expand and contract naturally with concrete movement. Polyurethane sealant, applied over the backer rod, will prevent sand, gravel, and other debris from entering the crack. This ensures that the expansion joint will be able to function properly.
In cases where street creep has damaged foundation walls, SettleStop® wall anchors can be installed to stabilize and restore them. A soil access point is required at each wall anchor location. Using a concrete saw, a technician cuts openings the garage slab at each soil access point. Once all access points have been made, FSM will dispose of all debris and keep the work site clean, safe and well organized.
Next, a plastic liner is placed on the ground around each slab cutout. The liner will keep your garage floor clean as technicians use a power auger to bore holes where earth anchors will be installed. The excavated dirt is saved so that it can be returned to the hole after the installation is complete.
Unlike helical tiebacks, foundation wall anchors need only a small 1-in.-dia. hole to be drilled in your foundation wall for each anchor’s steel rod to pass through. This is applicable for both poured concrete walls as well as concrete block walls. Once holes have been drilled, the steel rods are driven through the soil to meet up with the earth anchor holes made in the previous step.
Inside each hole, a steel wall anchor is attached to the rod that was driven through your basement wall. Holes can then be filled with soil and covered with poured concrete to restore the garage slab to its original condition. Soil pressure keeps each earth anchor in a fixed position, allowing wall anchors and adjustment nuts to exert pressure on the foundation wall. A triple-galvanized coating on all components ensures corrosion resistance.
Inside your basement, a steel wall anchor plate fits over each protruding steel rod. Technicians will tighten a nut on the rod’s threaded end to apply pressure against the foundation wall. The wall plate helps to distribute this clamping pressure.
Once installed, your wall anchor system will permanently halt the inward movement of your basement walls from expansive clay soils.
Once the wall anchor system has been installed, your contractor will adjust and tighten the nut on each steel rod to the appropriate amount to stabilize your bowed or buckling walls.
