Hydrophobic Polyurethane Grouts
Hydrophobic polyurethane grouts are injected directly into soft soils to provide a glue-like bond of weak or shifting soils. They can be injected to depths of up to 30 to 40 feet to provide a very secure base; and they can also be applied prior to construction and they have the capability of turning ordinary “ball-bearing” type contractor fill dirt into 700 – 1200 p.s.i. bonded soil (depending on soil types) sort of like turning your soil into a lightweight concrete.
Hydrophobic polyurethane grouts are activated by moisture, and they displace and vacate water during injection. Even swamp-like soil conditions can be bonded to provide load bearing, structural strength. And they cure to 90% load capacity in less than an hour.
