Polyurethane Concrete Lifting in Maryland, Northern Virginia & DC
Lift Sunken Concrete With Polyurethane Foam in Maryland
Concrete Slab Jacking Inc. is Maryland’s trusted choice for sunken concrete repair, serving local homeowners and businesses for nearly 30 years. As a licensed and insured Maryland contractor, we specialize in using advanced HMI polyurethane foam injection to raise and stabilize uneven slabs. Our high-density expanding foam is pumped beneath the concrete, where it expands and hardens into a strong support layer. Because the foam cures rapidly, your newly lifted surface can be driven and walked on almost immediately. This lightweight foam will not add extra weight that could cause future sinking, and it completely fills any voids under the slab for long-term stability.
Maryland’s weather including wet periods and freeze-thaw cycles can cause soil to erode or shift under concrete slabs, leading to settlement and cracking. Our polyurethane lifting method works in both wet and dry conditions, acting like a flexible spring that compacts the soil as it fills voids. Whether it is a sunken driveway, uneven sidewalk, sagging patio, or basement floor, we lift and level it back to its original position. This modern, minimally invasive process saves you from costly concrete replacement and restores a smooth, safe surface across your Maryland property.
The Benefits of Professional Slab Lifting
Choosing professional foam lifting offers many advantages for Maryland property owners, including:
- Enhanced Safety: Lifting sunken slabs eliminates tripping hazards and creates a stable, even surface. Properly leveled concrete helps prevent accidents on walkways, steps, and driveways.
- Curb Appeal and Value: Level, intact concrete improves the appearance of your home or business. Smoother, even surfaces boost curb appeal and can increase your property’s resale value.
- Durable Results: The injected foam forms a strong, permanent base. Once cured, the foam will not wash away, shrink, or deteriorate, so your concrete stays in place. We even back many lift projects with a 10-year warranty on surfaces like sidewalks and driveways.
- Cost Savings: Foam raising is much cheaper than tearing out and replacing slabs. In fact, concrete raising often costs less than half of a full replacement while achieving equally reliable results.
- Family-Owned Expertise: As a family-owned Maryland company, we combine experienced craftsmanship with fast service. Our foam lifting can often be completed in a single day with minimal disruption to your property. You save time, money, and the hassle of a major demolition project.
Why Use Polyurethane Foam to Raise Concrete
Polyurethane foam lifting outperforms traditional mudjacking in almost every way. Mudjacking which pumps wet slurry beneath a slab can be messy, time-consuming, and less effective. The heavy cement slurry used in mudjacking adds weight and can even worsen soil conditions, potentially causing further sinking. By contrast, our two-part polyurethane foam is clean and lightweight. It expands quickly to lift the slab and then hardens within minutes. Because it is lightweight, the foam does not overburden the soil, reducing the risk of new settlement. The result is a precise lift with less downtime and no muddy mess.
How and Why Foam Jacking Works
Our foam jacketing process is simple and effective:
Drill and Inject
We drill a few small holes in the sunken slab and inject high-density polyurethane foam into the voids beneath.
Fast Expansion
As the two-part foam is injected, it expands rapidly. This gentle upward pressure raises the concrete slab back to level and fills the empty space underneath.
Quick Cure
The foam cures and hardens within minutes. Once set, it forms a solid, lightweight support under the slab. You can usually walk or drive on the repaired concrete right away.
Minimal Disruption
Because we work through small holes, there is no need for heavy demolition or full replacement. The surface is clean and ready to use immediately. In most cases, the entire lift can be completed in a few hours.
This method creates a durable, lasting foundation under your concrete. The cured foam will not wash out or settle, so the repaired area stays level indefinitely.
