Cracks in cement don’t always mean you have to tear up the cement and re pour the slab. You can buy some extra time with a few quick tips. • You can fill the cracks in your cement with mortar or you can use Polyurethane caulk. • For cracks up to half an inch wide and half an inch deep, A Pour-N-Patch mix is ideal. • Since it is a ready-to-use product, simply pour or squeeze it into the crack...and smooth it with a small trowel or putty knife. When it dries, the gray color will blend with existing concrete. • Cracks larger than half an inch should be repaired with a vinyl concrete patch mixture or a fast set cement mix with a bonding agent. Refer to the manufacturer’s directions to determine which is best for your project. • For repairing cracks in cement, first, saturate the crack with water. • Then, mix the vinyl concrete patch or fast set cement mix according to package directions • Then force it into the crack, and scrape away the excess. • You can repair large cracks and holes in driveways or walkways with vinyl concrete patch or a fast set cement mix. An acrylic additive or primer/admixture should be added to the mix to improve bonding. • Here is a list of everything you'll need to repair cracks in concrete: • • Pour-N-Patch Product • • Vinyl Concrete Patch Product • • Fast Set Cement Mix product • • Acrylic Additive • • Trowel • • Putty Knife • • Mixing Pail • • Water • • Steel-Bristled Brush • Repairing cracks in joints have at least three purposes: • It gives the concrete a neat appearance • It keeps dirt, small rocks, and other debris out of the joints • It minimizes water intrusion to the sub grade through the joint • Joint sealants can be used on driveways, walkways, patios, pool decks, and parking areas. • In deep joints, install baker-rod • Chisel out the crack to create a backward-angled cut, using a cold chisel and a hammer. • Clean loose material from the crack using a wire brush, or a portable drill with a wire wheel attachment. • Apply a thin layer of bonding adhesive to the entire repair area using a paintbrush. The bonding adhesive helps keep the repair material from loosening or popping out of the crack. • Mix vinyl reinforced patching compound, and trowel it into the crack. Feather the repair with a trowel, so it is even with the surrounding surface. • Variation when repairing a large crack: • • Chisel out the crack and clean loose material from the crack as listed above. Then pour sand into the crack to within ½ of the surface. Prepare sand- mix concrete, adding a concrete fortifier, and then trowel the mixture into the crack. Feather until even with the surrounding surface using a trowel. • For larger problems in cold climate: • Frost heave is very common in cold climates. Moisture in the ground freezes and the concrete is pushed upward. • Be sure to get the advice of a local soil engineer on sub grade preparation for your area and material you will need to prepare sub grade. • Remove the concrete • Remove the sub grade • Replace sub grade with compactable material you may be able to use existing material. • Compact the sub grade • Pour back concrete • Always be sure to read and follow the manufacturer’s directions carefully.
