A building and garage restoration contractor observed extensive cracks in the concrete and water infiltration through the foundation walls.
Working within the underground parking garage, 3/8 inch diameter holes, every 8 inches at a depth of 10 inches were drilled. Alternating holes were drilled on each side of the crack, at a 60 degree angle to intersect the crack at the mid-point of the foundation wall. Plastic packers were then installed into the drilled holes, and flushed with water/acid solution to rid debris from the holes and the crack itself.
Chemical grout was then injected into the drilled holes filling the fine cracks and forming a flexible foam barrier, sealing the crack, preventing further water discharge.
Loose fill surrounding a manhole structure required stabilization. Multiurethanes technicians injected Universal Resin through vertical injection pipes to stabilize the fill prior to cutting through the structure wall.
A large contractor was looking for a uniquely qualified partner to complete concrete crack injection work at Little Long Generating Station, a remote Northern construction project.
This job involved precision drilling work for crack injection to avoid the unknown conduits and pipes buried within the structure. Multiurethanes experienced technicians completed the project professionally and on time.
