Street creep is a problem that is caused by thermal expansion and contraction of exterior concrete pavement that surrounds a home. As this concrete expands against a driveway with inadequate expansion joints, the driveway is pushed against the garage slab, which in turn pushes against the foundation, causing damage.
While this is a slow process and can take many years to develop, the damage can be very serious when it manifests on your foundation walls.
The GeoLock® Street Creep Repair System will prevent future damage with new expansion joints in your concrete driveway as well as a steel wall anchor system that reinforces and straightens your foundation walls.

Like many materials, concrete expands when it’s hot and contracts when it’s cold. Contractors place expansion joints in sidewalks, driveways and other exterior slabs so that temperature-induced expansion and contraction won’t cause a slab to crack.
Problems with street creep begin to arise during the cold winter months, when the widened joints become filled with materials like sand or gravel. As temperatures rise again during warmer weather, the concrete expands. But if joints have filled with sand and gravel, they can no longer absorb this movement. Instead, one slab will push against another.
Once they’re filled with debris, expansion joints can no longer do their job. The entire expanse of concrete expands as a single unit, causing the street to “creep.” Street creep exerts tremendous pressure at the edge of the concrete, where a driveway meets a garage slab or a house foundation wall.
Street creep can be detected by these four common signs:
At Mission Home Services, we address street creep repairs with the GeoLock® Street Creep System. This innovative foundation repair product solves the problem in two ways:
There’s no way to stop the normal expansion and contraction of concrete slabs that occur with temperature changes. But it is possible to eliminate the damage caused by this movement.
Your foundation repair contractor will install one or more new expansion joints in your driveway to allow individual slabs to move without pushing against the garage slab and your foundation wall.
Each joint is filled with a resilient backer rod and a durable, flexible polyurethane sealant.
Once the expansion joints have been created, we install the GeoLock® Wall Anchor System. These wall anchors will stabilize foundation walls that have been pushed in, cracked or otherwise damaged by street creep.
Thanks to the GeoLock®’s adjustable capability, it may be possible to go beyond wall stabilization and even use the system to restore wall straightness.
During installation, holes are cut through the garage slab floor, and soil is augured out to allow for earth anchor placement. Next, holes are drilled through the foundation wall so that a long, threaded steel rod can connect each earth anchor to a steel plate that applies clamping pressure against the wall.
Once the earth anchors, rods and steel plates are in place, nuts are tightened on the rods to stabilize the wall and (if possible) pull the wall back towards its original position. The holes in your garage slab are carefully patched and your worries about street creep damage are a thing of the past.
Installing new expansion joints, combined with the Geo-Lock™ Wall Anchor System, is exactly what you need to stabilize foundations that have been damaged by street creep! Mission Home Services is experienced in applying the right techniques for your home.

“From the very beginning of the transaction, Dave, the owner was honest, upfront and professional in his interactions with me. I am more than pleased with the work but more importantly, his values instilled in me a sense of confidence in small business owners who still believe in doing what is right for customers and providing outstanding customer service. I HIGHLY recommend Mission Home Services!”
“Dave was super responsive and went above and beyond in getting my basement project completed. He kept in regular contact with me on updates to the project, expected delivery of materials, and on permitting status. Very reliable and did a terrific job on my basement retaining wall.”
“First of all, I don’t usually do reviews; however, I was so impressed with the guys at Mission Home Services that I felt the need to let others know. We had them out to inspect our basement and give us an estimate on waterproofing it for future renovations. The representatives gave us a great education on not only how a basement leaks, but also how ours was leaking and the correct method to fix it. We highly recommend this company!”
