At Foundation Systems of Michigan, we recommend repairing damage done to your foundation by street creep with the GeoLock® Wall Anchor System.
Designed by Supportworks, Inc., this street creep repair system is currently used by hundreds of foundation contractors across the United States and Canada. 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, GeoLock® 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 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 may attempt to straighten the bowed or buckling walls over time by tightening the nut on each steel rod.

The existing expansion joint between the driveway and garage is fully compressed.
Even when the joint appears wide enough at the surface, the concrete may still be in contact underneath. This means that when the street expands with heat, your driveway is being pushed into the rest of your home.
The foundation walls on either side of the garage door are being pushed inwards by the driveway slab.
This is a sign that when the concrete pavement expanded and lengthened, pushing into the concrete driveway, there was insufficient compression space within the expansion joints. The only place for the driveway slab to go was through your garage walls.
Gaps have formed behind the foundation walls on either side of the garage door as the garage slab is pushed rearward.
Installing new expansion joints in the driveway and installing wall anchors will restore your foundation walls to structural stability.
Basement walls or foundation walls are pushed out by the garage slab.
At this stage, the damage caused by street creep has lead to a potentially serious foundation issue. It's important to address this soon -- before the damage becomes any more significant.
