Soil grouting technique principle is according to certain proportion, injecting polymer materials to soil, after reaction materials volume will expand rapidly and form a kind of foamy solid.
Polymer grouting materials can fill any escapes and cracks along the way it pass , and they can further consolide and strengthen surrounding materials at the same time
Generally waterproof engineering is conducted under the condition of continuous flow scour, so only using high-early-strength materials can prevent water erosion damage to materials in the process of construction
