Sometimes, installing a concrete slab for a driveway doesn’t go as smoothly as planned, resulting insevere cracks. Don’t ignore them -these deep gashes aren’t only tripping hazards, but they also lower your curb appeal and affect the value of your home. To help you out, here’s how to fix them.
Chisel the Crack
The first thing you need to dois the “keying” method. This helps the filler bond better with the concrete. Use a hammer and chisel to knock away crumbling pieces and level off the working surface. Hit the area at an angle to make an inverted “V” shape.
Remove All the Dust
Once you’re done, remove the debris inside the crack with a wire brush or broom. Vacuum all the dust left behind. You can alsowash this area to clean it thoroughly, but make sure the water doesn’t pool up. Let it dry completely before moving on to the next step.
Apply the Concrete Patch
If the driveway has hairline or narrow cracks, it’s best to start the process by stuffing the damaged parts with a backer rod using a screwdriver. This creates a base that helps hold the filler material in place. Then, apply a vinyl patching compound on the concrete. Using caulk over this kind of fissure isn’t effective because it tends to peel off the surface over time.
To get the best epoxy application for your concrete slab crack repair, use a putty knife or mason’s trowel. Pack the fillerinto the crack.
After it has completely settled,eliminate air bubbles by pressing down firmly on the filled areas, even out the surface. Don’t let anyone step on them, and leave them overnight to cure so the material fully bonds with the concrete.
Seal the Concrete
Concrete is highly porous, which means it absorbs moisture easily, leading to more damage. To avoid headaches, seal your driveway after patching up the cracks. This protects the surface against wear and tear and prolongs its life.
