What is chemical grouting?
The mixture of sand, cement, water and chemical is called chemical grouting. In this, gravel is used instead of ballast for strength. Chemically, it includes acrylamides, acrylates, epoxy and sodium silicates. All these chemicals are used for water proofing. Chemical grouting is mainly used for filling cracks, preventing soil erosion, stabilization of soil etc.
How is grouting done?
Chemical grouting is done in two ways. Its first process is called two shot, in which the pipe is drilled and inserted inside the ground. After this chemical grout is filled in it. Due to the process of chemical reaction, the soil becomes solid at a rapid rate. Its second process is called one shot. In this method, the chemical mixture of grouting material is poured inside the ground after pre-preparation. In this process it takes some time to harden. This one-shot process is mostly used for boreholes.
