Chemical grouting, or the practice of adding grout to help stabilize soil, is something that is done for various purposes. One situation in which chemical grouting is commonly used is when tunnels are being installed. These are a few reasons why chemical grouting really makes sense for these types of projects.
Keep Tunnels Safe
If people are going to be using the tunnel, such as if a tunnel is being installed as a part of the road or highway or if it will be used for employees who are transporting supplies to and from a mine, then it's important to make sure that the tunnel is safe. If a tunnel collapses while people are inside, their lives can obviously be put in danger. Chemical grouting helps make sure that tunnels are secure and safe. This can save lives, and if those who use the tunnel know that these steps were taken during the tunnel's installation, they might feel safer about using the tunnel.
Prevent Leakage Into the Ground
Chemical grouting is also wise when tunnels are being installed because they help prevent leakage into the ground. Even though chemical grouting might include chemicals, the substances that are used are generally considered to be safe for the environment. The things that will be inside of the tunnel once it's put into use, though, might not be safe for the environment at all. If a tunnel is going to be used for things like transporting oil, for example, there is a big environmental concern. With chemical grouting, though, cracks that can cause leaks are prevented.
Save Money on Tunnel Maintenance
Tunnels are not cheap to build. Because of this, it's easy to want to cut corners to stick to a budget. The problem with this, though, is that if the tunnel isn't installed properly in the first place, it's going to be a lot more likely to fail. This will lead to future costs when the tunnel has to be repaired, and it will lead to a lot of hassle later on when the tunnel has to be taken out of use so that these repairs can be made. Chemical grouting helps maintain the integrity of the tunnel for much longer, reducing these problems.
Chemical grouting is a technique that is commonly used when tunnels are being constructed. If you're involved in a tunnel building project, you may want to do your research about chemical grouting so that you can understand its importance, too.
