What Is Poly Jacking?
Poly jacking, also known as poly lifting, is a method of foundation repair in which polyurethane foam is injected into the ground beneath a foundation to restore it to a level position. About 15 minutes after being injected, the foam cures, then expands before hardening completely, effectively lifting the unlevel concrete. Poly lifting has become a popular method for leveling uneven sidewalks, driveways, patios, and pool decks because it is relatively cost-effective and can be performed more quickly than other well-known methods like mudjacking, and with far less mess.
Mudjacking involves pumping cement grout under the uneven concrete. The cement grout hardens, but to support the lifted concrete, this method relies on underlying soils. These soils are affected by the same elements that lead to cracking and settling, making it difficult for a contractor to guarantee their work.
How Effective Is Poly Jacking?
The polyurethane foam used in poly jacking is remarkably strong. One square foot of the cured foam can support a load of more than 10,000 pounds. What’s more, the foam is impervious to water infiltration and will not react with other chemicals. It is also highly resistant to erosion as well as rodent or insect infestation. In most cases, poly jacking can provide a lasting solution to issues with settling concrete slabs.
