Cement Slabjacking vs Polyurethane

As a multi-generational, family-owned business, Level Line Concrete Solutions believes in doing everything we can to protect the environment for generations to come. As such, we only use a non-shrink grout comprised of clay-based soil, brick sand, and Portland cement for raising sunken concrete. 

In recent years there has been a push to use polyurethane spray foam (also called Polyfill, Poly Jacking or Poly Level) for concrete lifting, which injects a reactive, two-part chemical formula into the ground beneath your concrete. When the two chemicals react they produce expanding foam.

If you are going to use this product at your home or business you should understand the chemical characteristics of it, and other concerns with it, so we’ve compiled some sources below with further information.

Our product guarantee

We highly encourage our customers to do research and choose a concrete solution that’s right for you. You may find claims that concrete slab lifting isn’t permanent, and sometimes that may be true. Luckily, at Level Line we stand by our product.

As background, 15 years ago the product the Slabjacking industry pumped was not as permanent as now, but just like Apple has improved on the first iPhone, we’ve innovated and improved to provide the best solution, while maintaining an affordable price for our customers. What hasn’t changed is that we always have and always will stand behind our work and correct any deficiencies reported to us .

Our guarantee is that if you experience even a 1/4” drop over a 2-year period and we will come back to correct it. This rarely happens, but if it does , there is no cost to you, the customer.

Competitor guarantees will often have additional costs associated to the return of service crew.

Be prepared. It is important to understand that if the slab sank due to water, the underlying water issue has to be resolved or the slab will sink again, regardless of whether cement or polyurethane foam are used. Even if you replace the slab with new, poured concrete the new slab will fail as well.
