Street Creep Repair Specialists Serving Florida & Georgia
Pushing problems. Street creep can damage a foundation when concrete slabs in a driveway or road expand or move, pushing against the edge of the foundation.
Custom-designed wall anchor system for street creep repair
If your concrete slab driveway and foundation is cracked or damaged, the problem may not actually be in your home. “Street creep” occurs when the road expands or moves, pushing against your foundation and creating pressures that cause cracks and compression.
If you have expansion joints that seem compressed, interior or exterior foundation cracks, or a garage floor pulling away from garage wall, you may be dealing with a street creep issue. Alpha Foundations provides expert solutions to this problem, and we can help you repair your home.
We provide free, no-obligation foundation repair quotes in Tallahassee, Jacksonville, Orlando and throughout the nearby areas in Florida and Georgia. Call or e-mail us today to schedule an appointment!
Here are three common conditions where street creep can cause foundation damage (click to expand).
What causes street creep damage?
Street creep is a common foundation problem that’s caused by the thermal expansion and contraction of concrete streets and pavement surrounding a home.
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.
Expansion joints divide a large expanse of concrete into individual slabs that can expand and contract independently. Temperature fluctuations throughout the seasons will cause these joints to widen in the colder months and narrow during hot weather.
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.
Damage from street creep is a slow process – the elongation of a typical block-length concrete street is generally only a fraction of an inch each year. However, over time, the movement will add up to several inches, which will mean potentially serious damage to your foundation.
Symptoms of street creep damage
Street Creep can be detected by these four common signs:
Compressed Expansion Joints
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.
Garage Wall Damage
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 Behind The Foundation 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.
Repairing street creep problems
At Alpha Foundations, we typically use a two-part process to repair foundation damage caused by street creep. Our structural technicians first install new expansion joints to help take pressure off of the foundation wall. We also use wall anchors to stop inward movement of the foundation walls.
Our Wall Anchor System is the ideal solution for your street creep problems.
We use the following steps for street creep repair:
- Cutting new expansion joints: To prevent future expansion damage to your home from street creep, we’ll begin by cutting new expansion joints that will provide additional expansion and contraction space to end the street creep cycle.
- Filling expansion joints: All expansion joints are filled with a resilient foam backer rod that will expand and contract naturally with concrete movement. Applied over the backer rod, polyurethane sealant will prevent sand, gravel, and other debris from entering the crack, ensuring the expansion joint will be able to function properly.
- Creating access points in the garage slab: In cases where street creep has damaged foundation walls, wall anchors can be installed to stabilize and restore these walls. A soil access point is required at each wall anchor location. Using a concrete saw, a technician will create a square cutout in the garage slab at each soil access point.
- Drilling earth anchor holes: Our 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.
- Preparing the basement wall: Unlike helical tiebacks, foundation wall anchors need only a small 1-in.-diameter 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.
- Attaching earth anchors: 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.
- Installing wall anchor plates: 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.
- Straightening walls: 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.
