Polyurethane – Void Fill and Slab Lifting

Prime Flex 985 is a two component high strength structural polyurethane foam. It is mixed at a 1:1 ratio using a two component pump and is often used to fill voids beneath concrete slabs or behind below grade concrete structures. Prime Flex 985 is available in 10 gallon units, 100 gallon units, or 600 gallon units. It is available in standard and fast set times as well as two different expansion ratios (LX 10 =ten times expansion and LX 20 =20 times expansion). Prime Flex 985 may be injected using our Flow Master air operated pump.

Precision Lift 3.5# is a two component high strength structural foam designed for lifting slabs using our Precision LiftTM process. The method requires specialized equipment that heats, dispenses, and mixes the resin. The extremely rapid set time allows for precise control over the slab lifting operation to within an eighthof an inch (1/8”) or less of desired level.
