Performed microfine cement grouting and waterstop operations using polyurethane resins, and provided soil stabilization in cross passage tunnels along the road in a light rail transit (LRT) line construction project.
Voids within a century old church tower required a low-density fill to prevent water infiltration from migrating within the masonry structure. Multiurethanes technical team safely filled the existing voids using durable chemical grout materials.
A building restoration contractor experienced water leakage into the mechanical room. Polyurethane resin was injected to fill the holes, forming a semi-rigid foam barrier and preventing further water leakage.
A restoration contractor refurbishing the canal and lock gates found a joint that required to be sealed from infiltration of water. The joint was filled with epoxy, forming a rigid barrier, preventing the infiltration of water into the canal wall.
Applied a chemical grouting solution involving sodium silicate, delivered through sleeve pipes, after surface voids formed during a directional drilling project beneath an airport construction job site.
Our technical team developed a solution to lift train track crossings on wood ties by pressure grouting under the tracks. This new approach was fast, reliable and surprised the utility contractor, who had been looking for this solution for a long time.
