Polyurethane Foam Injection

Polyurethane Foam Injection

See how PolyLevel® is used to level commercial and industrial slabs and for other municipal applications!

The Foundation Supportworks PolyLevel® product line comprises polyurethane foams and resins used in various structural and geotechnical applications. Some of these applications include:

  • Void filling
  • Stabilizing and lifting concrete slabs and footings
  • Soil densification
  • Soil binder
  • Trench breaking

PolyLevel® Advantages

Lightweight – PolyLevel® weighs approximately 4 pounds per cubic yard, which is significantly less than the 120 pounds per cubic yard of typical fill material. This means there is almost no additional load added to the supporting soils.

High Capacity – Lifting action is a result of the expansion of the polymer, allowing for lift on much higher loads than typical mudjacking that relies on hydraulic pressure being contained under the slab.

Non-Invasive – PolyLevel® equipment can be used in limited access areas, is less messy than other methods, and can installed more quickly.

Accurate Lift – Calculated reaction time of the polyurethane foam allows for a precise lifting operation.

Waterproof – Polyurethane material is waterproof, so it will not wash out, and can be used to under-seal slabs as well as stop a variety of infrastructure leaks.

Cure Time – Quick cure time allows for immediate loading, even heavy traffic, within 15 minutes after injection of the material.

Environmentally Friendly – PolyLevel® is manufactured with recycled material that is safe for the environment.





Product Resources

Model PL100
PL100 is a single-part, nonexpanding polyurethane that is primarily used to bind loose granular soils.

Model PL220
PL220 is primarily used in pipeline and trenching applications as a trench blocker to prevent water from flowing along the pipe and eroding the backfill soils.

Model PL250
PL250 has a nominal free-rise density of 2.5 pcf and is mainly used in residential and low load applications.

Model PL400
With a nominal free-rise density of 4 pcf, PL400 is most often used in commercial, roadwork, and moderate to high load applications.
