Chemical Grouting
Chemical grouting may be your solution to soil issues caused by excessive water movement or less supportive, granular soil.
What is Chemical Grouting?
Chemical grouting is a type of pressure (permeation) grouting that uses chemical solutions with high bonding agents to fill in pockets in the soil and help prevent water movement.
Benefits to Chemical Grouting
Chemical grouting makes the most sense over traditional pressure (permeation) grouting either when the soil being worked on is highly granular (with significant sand content), or when the primary grouting purpose is to control water movement or decrease permeability. Chemical grouting does not use the aggregates the same as traditional cement-based grouts and so has a better ability to flow into soil without creating disruptions. For the same reason, it can better flow through the soil in order to create a more uniform water barrier. In short, the benefits of chemical grouting can be summed up as follows:
- Greater flow ability
- Less soil disruption
- Environmentally considerate options available
- Highly suitable to water control applications
- Applicable from interior or exterior of soil, tunnel or other structure
Chemical Grouting Applications
Water Control
- Water sealing cracks in rock or concrete
- Water control for granular soil
- Patching leaks in underground tunnels, tanks, elevator shafts, and mines
Structural
- Restoring structural integrity of cracks in rock or concrete
- Increasing load bearing capacity of granular soil
Before Working with Chemical Grouting
Make sure you are using the right tool for the job. Without the right engineering expertise and experience, you may not know the best solution for your application. The above information is informative only in giving general guidelines regarding chemical grouting and you should choose and partner with the right expert for your project application.
