One of the major causes of chipping or cracking is due to movements of tectonic plates. Slight tremors or earthquakes could be the reasons. These tremors might not be very dangerous, but they are enough to shake up these sidewalks or drive ways. Roots of trees also sometimes crack up the ground gradually. If so, try and take out the roots.

Small cracks can be fixed by you yourself. Go into a shop which sells such home repair items. Tell them about your problem and the sales people will be able to tell you which material you will need to fix it. Some times, you put in steel bars or metal grids in the concrete area which is cracked. Ask for professional help in such cases.

Now cracks can not give structural failures as there are easy ways to fill up the cracks. Pour-in concrete walls can be injected with low pressure epoxy or polyurethane foam. This permanent, cost-effective and reliable method is preferred by everyone. But a concrete block walls can’t have epoxy injection. The cracks are fully filled and the treatment arrests the seepage of water. Drilling is not needed to inject the treatment. The injection is made from the inside the no digging is required. Basement is the diciest place from where the seepage occurs and the complete building decays. Thus basement walls have to be repaired at the earliest.
