Filling Large Gaps In Concrete

My concrete driveway has eight large slabs.

Filling large gaps in concrete.

Fill the gap between a concrete patio and house. Fill larger gaps with foam backer rod sometimes called spline. Gaps in concrete whether they result from cracks in the slab or occur between the slab and an adjacent surface can serve as openings that allow dirt moisture or insects into your home. This can be found at well stocked hardware stores but not always at large home improvement centers.

So filling them should be a maintenance priority. Fill and smooth the joint. If the concrete cracks continue to reappear call in a professional to rule out any larger problems. The straight line gaps between the slabs has enlarged and some cracks are as wide as 2 inches.

Fill the crack with urethane caulk similar to what you would use for driveway caulk. Once you are done filling the crack use a small brush broom or even a block of wood to rub across your patch to help match the consistency of your patch surface with the surface of the original concrete. The driveway slopes down from my garage to the street. Caulking concrete cracks install backer rod.
