Introduction to chemical grouts technology

Concrete building crack is the main cause of concrete building damage, crack leakage is the most headache problem, because the cracks inside the concrete is completely ruleless. The general traditional plugging method is gouging the crack or leakage, and make surface plugging, but the result is here is blocked the other places begin to leak. Because the water  in the internal cracks is moving irregularly, then seepage from the weak part of the concrete.

Chemical Grouts generally is inject chemical materials to the cracks of its structure  by high pressure injection grouting machine and injection packers so as to achieve the purpose of waterproof, plugging, reinforcing and strengthening. It is often used to repair deep cracks in concrete structure. According to the grouting pressure and speed, it can be divided into high pressure quick grouting method and low pressure slow grouting method.
