Repairing Cracks in Concrete Surfaces
Whether it makes up part of the basement or the driveway, concrete can suffer cracks as it often has to withstand a significant amount of weight. Being able to repair cracks that develop will help to ensure that the defect does not worsen and the surface can successfully retain its strength.
Hairline Cracks
Minor cracks in concrete can be rectified in the same manner as cracks in other materials with the use of a filler. Use a pallet knife to work a silicone-based filler into the gap as deep as possible and use a scraper to remove the excess and level out the compound on the surface.
Deep Cracks
Scrub the affected area with a wire brush to clean the surface in preparation for accepting the fresh concrete. Mix a ready-made concrete in accordance with the instructions and pour it into the crack, ensuring it is properly filled.
Jagged Cracks
Deep, jagged cracks will often contain small fragments of concrete that have come loose, which can be lifted free by hand. Use a chisel and hammer to dislodge loose particles and widen the gap to make the repair process easier.
