Cracks are inserted into large plains of concrete or asphalt to provide flexibility. In sidewalks, cracks are used to form a grid and the grid size is based on the surface area of the concrete or asphalt. When tree roots or something like that grow under the pad, they increase the risk of pushing the pad up. if the pad is one solid piece, it will end up breaking. In bridges, cracks are inserted to provide flexibility. When the wind blows, the bridge will slightly move. This is to prevent the major damage of how bldgs and bridges used to get when storms or natural disasters occured.

How to Waterproof a Crack in Basement Concrete?
Thousands of homes have basement floods each year because of cracks in their concrete. The best thing to do to prevent it happening again is filling the crack. A layer of polyurethane foam can be the solution to keep water away. This is not a job that must be left to professionals because any homeowner can do it themselves.The first thing you need to do is clean the area of the wall that has the crack. A wire brush will get rid of any loose dirt and dust. It will also tear off paint because that will get in the way of the repair. Then, you should mix half of a cup of the surface sealer. You should put a small ball of the sealer at the end of an injection port. Put this port over top of the crack in the wall. You should start at the lowest point of the crack and make sure that the sealer is not covering the crack. Then, you can add more ports, separated by between half of a foot to a whole foot.When ports are in place, you should completely cover the crack with the sealer. The sealant should be allowed to epoxy onto the ports for ten minutes. You can cover the crack with what is left of the seal epoxy after this time. You will have to wait one hour for it to cure. By this time, a fingernail would not be able to mark on the seal. Water should be put into the highest port inside the crack to help make the polyurethane foam expand.The polyurethane lock can now be unscrewed. A mixer can then be put on top of the cartridge of polyurethane. Then, put the locking nut back on the cartridge. You can now put this cartridge into your caulk gun. Begin at the bottom of the crack and put the mix into the port. The polyurethane can then be injected into the port. It will have to be done slowly so the polyurethane can expand and fill in the crack. When it reaches the water, it will start to expand into a foam.
