PolyLEVEL Advantages

Friday, March 25th, 2016 by Susan Xiong

PolyLevel is able to fit the needs of any job, large or small. PolyLevel is a two-part urethane polymer that expands into rigid, structural foam to fill voids, stablize and lift concrete, and offer solutions to a wide range of geotechnical and structural appications. 

PolyLEVEL Advantages:

Lightweight- PolyLEVEL weighs approximately 4-6 pounds per cubic foot when installed, which is significantly less than the 120 pounds per cubic foot 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 a slab.

Accurate Lift- Calculated reaction time of the PolyLEVEL foam allows for a targeted, precise lifting operation.

Waterproof- PolyLEVEL is fully waterproof so it cannot washout. In addition, because it cannot take on water, it is not impacted by freeze/thaw cycles. Additionally, PolyLEVEL can be used to under-seal slabs and stop a variety of infrastructure leaks.

Non-Invasive- The equipment used to install PolyLEVEL can be used in extremely limited access areas, is far less messy than other methods, and can be installed more quickly.

Cure Time- Quick cure time allows for immediate loading, even heavy traffic, within 15 minutes after injection.

Compressive Strength- The in-place compressive strength of commercial grade PolyLEVEL material is minimally 11,000 pounds per square foot, and often exceeds 15,000 pounds per square foot.

Consolidates Soil- As PolyLEVEL foam exerts the energy to lift a slab, it is placing an equal amount of pressure on the soil beneath the slab. This process not only fills the void and raises the slab, but also densifies the soil below.
