6.1 Technique presentation
6.1.1 Principle of expanding resin injection
This technique involves injecting an expanding polyurethane resin into the subsoil of a structure's surface foundations, and sometimes pavements. The resin's ability to expand enables it to displace and densify the injected soil. This densification gives the soil improved rigidity and strength.
Polyurethane resin is made up of two liquid components which, when mixed in perfectly defined proportions, transform into a rigid,...
