Street Creep

Street Creep ProblemsStreet creep occurs as the concrete in roads, driveways, sidewalks, and garage floors expand and contract due to seasonal temperature changes. Concrete material naturally expands when heated and contracts when cooled. When contractors pour any concrete slab, they should create expansion joints between any adjacent concrete to attempt to control this movement. Joints and cracks in concrete become filled with gravel, sand, and other debris during the cold times of year when the concrete contracts.

When the temperature gets warmer, the concrete begins to expand, and the expansion joints are filled with debris. If there is too much debris inside of the expansion joint at this time, or the concrete has not been properly maintained, it will begin to put pressure against the adjacent concrete slabs.

When there is a lack of expansion joint, the streets put pressure on the driveway, the driveway puts pressure on the garage floor, and in turn the garage floor puts pressure on the home’s foundation walls.

The result of this “concrete creep” or “street creep” movement can include foundation walls bowing, rotating, or deflecting, and cracking.

Typical signs of street creep include garage wall cracks, compressed expansion joints, garage floor cracks, gaps around the garage door, and foundation wall movement or cracking.

Street creep can lead to serious problems in a home if it’s not fixed properly, including foundation problems which can lead to a loss in property value. Properly maintained and installed expansion joints are a simple solution. If the street creep is causing foundation wall bowing, leaning, or cracking, foundation wall anchors can be installed to stop any further movement of the walls. Wall anchors can be installed to restore the foundation’s strength and stability.
