Water is the main culprit in a major portion of foundation problems. If the foundation is of poured concrete, concrete block or stone, the continuous flow of water creates cracks which can often be disastrous if ignored.
Cracks due to water seepage are found in the corners of the walls, or where the bricks, stone or concrete slabs are joined together. If ground water has enough hydrostatic pressure to allow water to seep through the foundation, then cracks occur. These cracks begin as small hairline cracks and widen over time.
There are two basic methods to repairing foundation leaks in your home or basement - the urethane injection and drainage tile repair.
The urethane injection is a comparatively simple process. In this case, the crack is sealed first to prevent all the water oozing out. The holes are then made in the crack and an epoxy resin is injected into the crack. The repair is complete when resin fills the entire crack. Urethane injections cost only a few hundred dollars and the time taken for the entire work completed will not stretch beyond a couple hours. However, the urethane injections can only be applied to small cracks. Also there is the danger of reopening of the crack and water seeping in once again.
The drainage tile repair is a long process. The floor tiles in the affected area are uprooted and a first drain tile is fitted. This is then connected to a sump pump or any other legally permitted system water removal. Once this is done, the floor tiles are replaced. This process takes several days and costs run to thousands of dollars. However, this is a much more permanent than the injection. One problem may be the malfunctioning of the sump pump. This can cause flooding due to excessive leakage.
Urethane injections are okay if the crack is small, but if the crack has been ignored and has become large and gaping, it is best to repair it using a drainage tile. For larger leaks outside the house, a more extensive method is employed. A trench is dug at the affected site and the drainage tile is replaced if necessary. The trench is then filled - first with coarse gravel to make it waterproof and then with soil. This method is used even when dams spring a leak in their foundation.
Repairing foundation leaks is a costly business, but more than that is time-consuming and laborious. However, it is one of those repair jobs that just cannot be ignored.
