Membrane waterproofing (pressurized & non-pressurized) for tunnel and underground structures, PU grouting to arrest water ingress, soil stabilization before excavation or tunnel boring.

Question

Accepted Answer

Membrane waterproofing, PU grouting, and soil stabilization are essential for tunnel and underground structures.

Membrane waterproofing is a technique used to prevent water ingress into underground structures. It involves the application of a waterproof membrane on the surface of the structure.
PU grouting is a process used to seal cracks and joints in underground structures to prevent water ingress. It involves injecting polyurethane grout into the cracks and joints.
Soil stabilization is necessary before excavation or tunnel boring to prevent soil collapse and ensure the stability of the structure. This can be achieved through various methods such as soil nailing, jet grouting, and ground freezing.
