Economy Compels Spray Foam Contractors To Offer Concrete Raising
Put away your ladders!

All contractors around the country have been fighting the ups, and mostly downs, of the economy since 2008.  The housing/new construction market has been the among the hardest hit segments of the economy.  Many spray foam contractors ramped up during the housing boom that preceded the recent downturn by purchasing multiple rigs and adding overhead and staff. Unfortunately, much of the equipment is now underutilized and staffing is day to day.

In a previous blog, I stressed how spray foam equipment can be redeployed to allow spray foam contractors to earn high margins by injecting polyurethane under concrete to lift and level slabs.  The word is now ou

"Not Every Like Foam Is the Same”

Concrete Lifting Foam is Concrete Lifting Foam…Right?

There are special characteristics you need to look for when deciding what polyurethane  foam to use for lifting and leveling concrete.  Expansion is important, but what about set-up and cure times or adhesion?  In this blog, we are going to explore the truth about polyurethane concrete lifting foam and what questions you need answered before purchasing a foam for this special application.   

Foam Reaction Time

Does your polyurethane foam react too slowly?  Foam that reacts slowly is great for filling voids, but not for raising concrete.  If material reacts too

Concrete Jack

The Concrete Jack crew raised 300 linear feet of warehouse floor in 2 hours and 45 minutes in the loading dock area of a warehouse facility in Asheboro, NC.

HMI RR201 was used for this project.





The area was open for foot traffic during the work, which was done on a normal work day.  Each joint was opened to fork truck traffic immediately after repairs.

RaiseRite Concrete Lifting Inc.

Oconto, Wisconsin - November 3, 2011

RaiseRite was commissioned to raise a 15X45' section of Off-Ramp located in Oconto.  There was a low spot across the 45' of roadway.  Traffic would dip as it traveled across the problem area.

Polyurethane foam was injected under the slab filling voids and stabilizing the slab.  In addition to stabilizing the slab, additional polyurethane was injected to raise the slab back to level.  554 lbs of HMI polyurethane was used to complete this project.

The majority of the lift was 2 1/2" and took 40 minutes.  The complete project from start to finish took 2 1/2 hours to complete which included the main lift and void filling to sta

Concrete Jack

Problem:  Due to poor compaction of fill material of a cell tower site, half of the pad was settling, which caused an equipment building and generator pad to settle.  The installation contractor installed two helical piers under the equipment building to raise it back to level within weeks of original construction in 2008.  During the site visit, ground water was gushing out from under the slab out of a void that was created during the piering process and was accumulating surface water.

Job scope:  Concrete Jack's crew raised the settled generator pad using polyurethane foam, void filled under the building using polyurethane foam, which pushed the water out from the void during installation.  After void f
