How do you repair concrete cracks in patio and sidewalk?
Once concrete is cracked, there is no way to effect a real repair. You can use sealant to fill the cracks in, however. To do this, remove every speck of dust and debris from all the cracks, finishing with a hard blast of water. Let dry thoroughly, then fill in the cracks with Sonolastic NP-1 in silver-gray or limestone color, strictly following manufacturer's instructions. Pick the color that best matches your concrete. Do not substitute for the Sonolastic NP-1 . . . it is a proven, industrial strength product. If the cracks are deeper than 1 inch, tamp in some backer rod so that you have about a 3/4 inch crack depth to caulk. Backer rod is a round hard foam that comes in various diameters and lengths. The backer rod should be a little larger than the cracks are wide. You will probably have to buy several sizes to fit all your cracks. Do not caulk over the top of your concrete, just fill the cracks to the top.
Is cracking at joints acceptable after new pour of concrete?
Cracking at expansion joints is always acceptable and is the reason for the joint itself. There are two kinds of cracks, pretty ones and ugly ones! Ugly ones are random cracks where the concrete relieves itself from drying shrinkage in a random location within the slab of concrete which is normally not appealing to the eye. Expansion joints are placed at predetermined intervals within the slab where random cracks are weakened planes in locations where cracking is predicted prior to fresh concrete placement. All concrete shrinks when it dries, the larger the slab, the greater the overall shrinkage. When the tensile strength of drying shrinkage exceeds the tensile strength of the concrete, cracking will occur. Lets just hopes it cracks in a spot where we planned it instead of a location where didn't. By the way, joints should be cut at least 25% of the depth of the slab.
