​PRECISION CONCRETE LEVELING LIMESTONE-BASED ​MATERIAL
Picture

Limestone is very tough, durable and capable of withstanding the elements.  Because it’s so long-lasting, you can count on the materials to function as intended.  Our natural limestone material is mixed at each job site to adjust for each condition encountered.  Our formulation has the flexibility to fill voids and pockets.  This will result in using more material providing a more thorough complete solution.  Some competitor’s mixtures are can set up too quickly.  This creates a “pillaring effect” with material established as pillars and leaving voids throughout the affected area.

Limestone is the proven quickest, efficient, and most effective controlled concrete leveling method of repairing sunken concrete!
Less hassle, less down time and immediate use once it is restored and realigned with limestone.

Fully filling voids before lifting gives proper reinforcement while raising.  Modern limestone-based concrete leveling techniques exceed polyurethane by completely stabilizing beneath hollowed unsafe squares, giving even coverage below,  restoring the slabs with continuous support.

Professional limestone-based concrete leveling
 is the most preferred long term solution.  Less holes drilled per project.  Specialized trade for water erosion issues, unsettled subsoil, sinkholes, & unlevel concrete.  A fraction the cost compared to polyurethane lifting.

Our 100% natural crushed limestone rock offers strong, solid support.  Builders use rock, dirt, or sand under concrete and around the foundations for fill.  Absolutely no concrete company will pour new concrete on top of polyurethane foam.

​POLYUREATHANE FOAM
Picture
Polyurethane foam is a byproduct processed from crude oil.  Main ingredients are polyois and diisocyanate, both of which are identified as carcinogens and listed as Toxic Substances by EPA.  Other ingredients and exposure to its contaminants toluene diisocyanate, methylene chloride, hydrogen cyanide, Iscyanates are known neurotoxins or carcinogens causing cancer in animals.  Polyurethane (even best foam) breaks down in 10-12 years under normal conditions.

Waiting for chemical reaction to occur. If mixed incorrectly can be toxic. As seen, this newest polyurethane system may not raise the uneven concrete enough and/or over lift the panels attempting to lift or level them.

Polyurethane foam expansion sets fast.  Mounds of polyurethane injection leave pockets / voids. If left open, soil can erode, leading to unstable concrete that is susceptible to extra stress on the slabs structure or foundation. Water, rodents, or insects also can inhabit the space.

More money spent and more Injection drill holes needed, in hopes of pumping filler into hollow cavities below the empty, unsupported concrete sections, plus additional hidden polyurethane pumping charges and future costs of removal for foam fill product can incur.


Ask the contractor if their polyurethane is hazardous in liquid form, before sprayed. Polyurethane foam is not accepted by concrete recycling companies and must be properly disposed of.  Know the facts and safety before deciding which method you’ll choose.
