Patching cement driveway cracks is crucial to prevent water from getting in the cracks and creating additional deterioration. Repairing driveway cracking also improves the “curb appeal” of your property.
Prior to commencing the repair, check out the area around your driveway for the origin of the crack. Growing tree roots, impacts and heavy objects sitting on the driveway could be the source of the trouble.
Ponding water is one of the most common cause of driveway cracks due to the fact that water slowly permeates into the concrete, expanding and contracting with temperature changes.
Before you begin with repairs, clean the crack to ensure the surface of the driveway can bond with the repair materials. Break off any loose concrete with a screwdriver or chisel without making the crack more substantial. After scrubing the crack get rid of any other debris with a wire brush, air compressor or shopvac.
For smaller crack repair, utilize a textured caulk, concrete sealer, or pourable grout exclusively made for concrete. With concrete sealer or grout, wet the surface of the concrete lightly with water.
If you are applying concrete caulk, it will need to be applied to a dry surface. Fill the crack and use a pointing trowel to press the product into the crack. When using caulk make sure to slightly over fill the crack to take into account shrinkage after drying. If the crack is more than a half inch inch wide, then it may be smart to secure a concrete contractor’s opinion regarding the cause and repair.
