The concrete foundations are of two types – concrete block and poured concrete. The poured concrete is a modern way of placing foundations, while concrete blocks are more traditional. The cement blocks are preferred for their visual appeal and strength. However, over time there may be a degradation of the concrete.
The main cause of cracks in the concrete foundation is water runoff. Such cracks caused due to leakage of water are fine, fine line. May extend over time, but are present only in those areas where runoff occurs. In order to repair cracks in the exhaust, it is necessary first to investigate the source and the point that leakage originates.
There may be other reasons for the concrete foundations to crumble. The soil can lose its moisture content in summer. There may be underground roots that can wither and die. These are natural cause’s soil to shrink and hence the foundation may move. Although this movement is gradual, overtime will cause cracks to occur. These cracks will be large gaping, running across the entire length of the foundation. They may even be in the form of tiny holes in certain places.
Whatever the reason, the cracks in the foundation are very risky if ignored. Repair should be done as soon as possible. The difficulties involved in the repair process are influenced by how large the cracks are.
For the moisture created tiny cracks, the repair is relatively simple and can be done by almost anyone. These cracks should first be brushed clean with a wire brush. A jet of water can be passed to remove all loose concrete particles within the crack. The crack is then allowed to dry thoroughly and filled with concrete caulk. If the crack is large, then it is packed with materials that are specifically available patch for the concrete. These materials must be wet patch when applied. Are limestone based, and expand as they dry, filling up the crack completely. The final touch is to apply a sealant to the crack repaired.
But if the crack is sinister and not the kind of do-it-yourself, then it is most prudent to shell out some bucks and hire some good repairmen. Such cracks occur due to stems that may have rusted inside and have seized, or because of deterioration of materials present within the concrete. Some cracks in the exhaust when ignored can also reach dangerous levels. Such cracks are found in more concrete poured.
Contractors treat the concrete foundation with injections of urethane to extract water dock. They may even excavate the area around the foundation and replace the defective tiles or build a provision for water to lose contact with the foundation.
