How Much Does It Cost To Repair Concrete Spalling?
Concrete resurfacing repairs spalling and costs an average of $2.50 to $4 per square foot, with a 24′ x 24′ driveway costing $1,400 to $2,300. Spalling happens when certain pieces begin to disintegrate.
It may also result in the driveway separating into thin layers. Spalling develops as a result of cold temperatures and direct exposure to harmful road salts.
The cost of repairing concrete spalling will depend on the extent of the damage and the size of the area that needs to be repaired.
If the spalling is minor, the repair may only require patching and sealing. However, if the spalling is more significant, the repair may require more significant work, such as resurfacing or even replacing the damaged concrete.
The cost of the repair will also be affected by the location of the damage and the accessibility of the area.
How Do You Repair Vertical Concrete?
Concrete damage is often repaired by filling it with a patch product. This, however, will not function if the surface is vertical. The patch will be dragged down by gravity.
A particular compound is used to repair vertical concrete surfaces that begin as a liquid or paste, dries swiftly, and will not shift during the repair.
This is epoxy, and its numerous applications should be a fixture in your home repair kit.
Step 1
Clean up any loose concrete particles in the affected area. Remove any dirt from the area and allow the concrete to cure. If the damage is too small for the injection ports, use a router to widen it somewhat.
Step 2
Cut along the tab attachments to remove the caps from the injection ports. Insert one port into the affected region. Place the remaining ports half an inch apart between the two anchors.
Step 3
Using a tiny paintbrush, apply epoxy resin thinly into and around the damage. Work the adhesive close to, but not over, the ports’ edges. Cover the damaged margins and part of the undamaged concrete surrounding it with glue.
Step 4
Allow approximately three minutes for the glue to become tacky. Fill each injection port with the ready-to-use epoxy. Insert the tube’s tip into the lowest port. Work your way up until you see epoxy in the aperture of the next tube.
Step 5
After each injection port is filled with epoxy, close it. Allow the epoxy to cure for 48 hours. Using pliers, pry each port open. Dry, stray epoxy should be lightly sanded with fine-grit sandpaper or scraped with a paint scraper.
