Most of the common problem faced by home owners can be foundation crack , basement wall crack. These problems are generally caused by over time, if concrete starts to shrink, due to structure damage or due to inner forces exerted by soil on the concrete foundation. These further can damage the interior part of the foundation.
Some of the ways to fix out the problem are excavating foundation concrete wall or digging all around the house and applying waterproofing. This method is quite expensive one. Out of all the other methods, epoxy injection is the finest one of all. Basically Epoxy are a two way component material which when injected into the crack gets mixed up.After some time of injection when it properly mixes, it forms a hard and strong material and hardens the wall. Either vertically or horizontally.Cracks are entirely filled from top to bottom or front to back. This method of crack repair can not be used in concrete block walls and floor cracks. Rest all the concrete foundations can be repaired with the help of epoxies.
The process of epoxy injection works such as firstly surface ports are attached with special paste over the cracks. Then once all ports are attached the remaining cracks and surfaces left are again sealed out with surface paste, which helps to keep epoxy in the cracks to harden. Lastly after all the above procedures epoxy is injected into the crack from the ports which are at lower surface. The liquid paste is injected into the epoxy cartridge which is inside the port where it flows all way around the crack. If the paste starts coming out of the port, stop filling paste into it and then start injecting to other one.Similarly fill all the ports by the same process.
Epoxy are injected to make the repair, to stop water or to structurally strengthen the foundation cracks. The foundation crack repair and basement wall crack repair are done from the inside of basement. Epoxies are injected in the liquid form. When two parts are mixed, the mixture forms a semi-stiff form after twenty to thirty minutes when applied. Then after few hours, it becomes rigid. Finally the whole process take around a week times to be structurally strong enough to seal the water coming from cracks.
In most of the cases, epoxies are harder and stronger than concrete itself. Once foundation crack repair and basement wall crack repair is done, the crack will not leak water. This method of crack repair is very useful and have following advantages :-
1. Foundation crack and basement wall crack are sealed from water.
2. Epoxies have high tensile strength and hence is stronger than concrete.
3. Epoxy injection method is relatively cheap as compared to other crack repair methods.
4. Epoxy injection repair method structurally repairs the concrete for more than 20 years.
Epoxy Injection method will help you best in removing water and other structural problems with the foundations and basements and provides you with a living space which is clean, safe and loving for home owners too.
