Concrete Foundation Crack Repair

Over a period of time, due to exposure to extreme weather conditions, foundations tend to become worn out and start cracking. Cracks can also occur due to the natural process of settling and shifting of ground every few years. They are a common problem, and can be found in basements, walls, or in the garage floors.

If left unattended, these cracks can be a big problem, leading you to spend a lot of money on repairing them. The water seeping through can damage your expensive belongings, but it also invites other troubles such as mold or mildew.

Fixing foundation cracks is a quite a difficult task. In the past, inefficient solutions such as application of patching compounds like silicone or caulking were commonly employed. For a complete and lasting repair however, a professional repair company should be contacted as they will be equipped with the tools and materials to get the job done right.

A few steps and procedures must be followed in order to execute the proper repair. The first step is to scrape and clean any loose particles such as debris from inside the crack. You may find very small pieces of broken concrete between the cracks which must be completely removed if you want the repair to be effective.

Before injecting the resin, you must first determine the exact size of the crack as this will help you prepare the crack for resin injection. You will find tar and other patches around hair cracks that must be removed by grinding with the diamond disc paint. The next step is to drill holes measuring two to three inches along the crack to install and seal the injection ports.

The ports have to be flushed with high pressure water from the top after which you must inject the PU. Start injecting the viscous liquid from the bottom until it comes out from the next port. After sealing the port with a plastic plug, and continue on to repeat the procedure.

Polyurethane injection sealers are highly popular today due to the flexibility it offers. It expands filling the crack completely before hardening thereby ensuring that there is absolutely no future water leakage.
