Construction Case: Injection Work

Injecting a solidifying agent into the voids of sandy soil! Introducing a method to improve the stability of the ground.

"Injection grouting" is a method of improving sandy soil by injecting a solidifying agent (chemical solution) into the voids of the soil to stabilize it. First, a survey is conducted to check for any obstacles, and the construction site is marked. A boring machine is set up, and while supplying drilling fluid (Chemical A and B), the drilling rod is used to inject the solution under pressure, drilling to the specified depth. In the first stage, a fast-setting type of chemical is used to fill large voids in loose sand layers and cohesive soil sections, preventing the injected material from diffusing or leaking from the injection site. In the second stage, a medium-setting to slow-setting type of chemical is used to permeate and inject into the smaller voids of sandy soil that contains a significant amount of medium to well-compacted sand layers and cohesive soil, achieving a solid consolidation of the ground. Once the specified injection amount for one stage is reached, the process moves to the next stage, and after all stages are completed, the chemical solution is replaced with water to fill the injection holes while withdrawing the rod. *For more details, please refer to the related link page or feel free to contact us.*
