When it comes to raising and leveling concrete, polyurethane injection has become the preferred solution thanks to its clean installation, precision, and long-lasting results. But just choosing polyurethane isn’t enough — the quality of the equipment, materials, and installation process makes all the difference. To get a repair that truly lasts, it’s important to work with a contractor who specializes in polyurethane concrete raising and has the experience to do it right the first time.
The Right Polyurethane for the Application
Not all polyurethane materials are created equal. Different formulations vary in rates of expansion, density, and how they interact with moisture (hydrophilic vs. hydrophobic properties). The right polyurethane must be chosen based on the specific application. Some contractors prioritize yield (how much the material expands) over durability, using lower-density foams that compress over time. This approach may cut costs, but it results in weak, unstable repairs that won’t last. The best polyurethane for lifting concrete must be strong enough to support the slab long-term without excessive expansion that creates unnecessary voids or instability.
The Cheapest Bid Can Be a Sign of Trouble
This project shows what can happen when price is the only deciding factor. The previous work was done with too few injection points, leaving large voids unfilled beneath the slab. Without proper support, the foam was overstressed, and the concrete began to settle again.
Here are a few common ways cut-rate bids are made possible:
Using lower-grade or high-yield material to save costs
Reducing labor by drilling fewer injection points
Prioritizing speed over long-term durability
While a low price might look appealing upfront, improper installation often leads to problems resurfacing — and paying for the same repair twice. At Acme, we focus on doing the job right the first time, giving you peace of mind and lasting results.
Think You're Getting a Great Warranty? Read the Fine Print!
Some companies boast impressive warranties, but if you read the fine print, you might find they don’t actually offer much protection. Many warranties are written in a way that benefits the contractor more than the customer. For example, a six-year warranty might seem reassuring, but exclusions and loopholes could mean little to no real coverage. If a company cuts corners on materials and installation, their warranty likely has built-in ways to avoid liability. Before trusting a warranty, always read the terms carefully and ask questions to ensure you’re truly covered.
Choose a True Specialist
Not all concrete raising companies are the same. Some contractors include polyurethane lifting as one of many services, while at Acme Concrete Raising & Repair, it’s our sole focus. Specializing exclusively in polyurethane concrete raising means every project we take on is held to the highest standards — because our reputation depends on it.
We’ve invested years into perfecting our Smart Lift System®, training our crews, and refining our processes. Our certified technicians follow proven installation methods to ensure every slab is raised properly and fully supported. This dedication to doing the job right is why homeowners, HOAs, and property managers throughout Chicagoland continue to trust Acme for reliable, long-term concrete solutions.
The Bottom Line
A polyurethane lifting project is only as good as the materials and installation behind it. Choosing the cheapest bid or a contractor with a flashy warranty won’t guarantee success. Instead, work with a true specialist who understands the science behind polyurethane lifting and follows best practices to ensure your concrete stays stable and level for years to come.
