BEST Concrete Lifting in St. Louis MO

Concrete Lifting St. Louis, MO – Sidewalk & Patio Repair

Concrete slabs are a critical component of nearly every home, whether it’s a driveway, sidewalk, patio, garage floor, or foundation.

Over time, these slabs can settle, crack, and become uneven, often due to soil settlement, voids, or shifting pressure beneath the surface. This not only affects the appearance and stability of your property but can also pose safety risks.

If you’re dealing with sunken or cracked concrete, the solution isn’t always costly replacement. Instead, one of the most efficient and cost-effective ways to restore level surfaces is through concrete lifting in St. Louis, MO.

This process – also known as slabjacking – works by injecting an expanding polymer or foam beneath the slab, lifting and stabilizing it back into place.

Concrete Leveling St. Louis – Why Does a Concrete Slab Move?

Erosion 

A concrete slab sinks as the soil underneath shifts, often due to erosion. Rainwater saturates the ground, mixing with the soil, and when the water drains away, it carries soil particles with it. This process happens gradually as part of natural settlement or suddenly due to a broken pipe or ruptured drain.

If the ground under a slab feels loose or seems to be eroding quickly, it’s crucial to evaluate your guttering and plumbing systems. In some cases, downspouts or faulty plumbing may be draining directly under the slab, washing out the soil and creating voids. These voids lead to instability and uneven surfaces. If you’re experiencing this issue in your neighborhood, concrete leveling can help stabilize and reinforce your slabs before further damage occurs.

Climate and Soil Type

Other times, concrete movement happens due to the characteristics of the soil. If the soil wasn’t properly compacted before the concrete was poured, the slab may begin to sink unevenly over time.

Additionally, the extreme weather cycles in Missouri play a major role. In spring, heavy rainfall causes soil expansion, followed by hot summers that dry the soil, leading to shrinkage and erosion. In winter, the freeze-thaw cycle forces the ground to expand and contract, contributing to further settlement.

These repeated fluctuations accelerate shifting and can cause cracks to form in concrete surfaces. When this happens, repairing the slab with concrete leveling in St. Louis, MO is a cost-effective and durable solution.

Consequences

Concrete rarely settles evenly – one side of a slab often sinks more than the other, leading to an unbalanced surface. This uneven support can put stress on the slab, causing cracks and raised edges that become tripping hazards. Such issues not only pose a liability risk but also compromise the integrity of walkways, driveways, and patios.

Beyond safety concerns, an uneven slab can damage your home. It may redirect rainwater toward your foundation, leading to water damage and potential leaks in your basement or crawl space. Over time, excess moisture can cause wood rot in the structural flooring system (sill plate, floor joists, etc.), creating an ideal environment for mold growth.

If you’re noticing sinking or cracking slabs near you, it’s best to act quickly. Professional concrete leveling in St. Louis provides a long-lasting, efficient, and precise solution to restore stability and prevent further damage. Whether you’re dealing with sunken driveways, cracked sidewalks, or shifting foundations, an expert team can ensure a smooth, even, and durable surface for years to come.

Concrete Lifting Near You – How Does Slabjacking Work?

Concrete raising is achieved through a precise injection process. Small holes are strategically drilled into the surface, allowing a specialized material to be injected beneath the slab. This material fills any underlying voids, gradually applying enough pressure to elevate the concrete back to its original position.

Different materials can be used for this process – some companies rely on a cement-based slurry, commonly referred to as mudjacking. As the slurry hardens, it stabilizes the slab, but the process can take time and may not always provide lasting support.

At Acculevel, we use high-density polyurethane foam, which we have found to be the best solution for long-term concrete stabilization. Unlike traditional mudjacking, this lightweight yet durable foam expands immediately upon injection, lifting the slab with precision.

The rapid expansion allows for greater control over the leveling process, reducing the risk of future settlement.

If you’re looking for concrete lifting near you, our expert team in St. Louis, MO, is ready to provide a reliable and long-lasting solution. Whether you need a driveway, sidewalk, or foundation leveled, we ensure a smooth, efficient repair that restores both function and safety to your property.

Concrete Leveling Near You – Benefits of Slabjacking

Convenience 

One of the biggest advantages of slabjacking is how quickly it restores uneven surfaces. The polyurethane foam injection process sets up almost immediately, allowing you to walk on patios and drive on garage floors within an hour.

This makes it a far more efficient solution than traditional concrete mixtures, which can take several hours – or even days – to fully cure. The curing time also depends on weather conditions, including temperature and soil moisture levels, which can slow down the process for alternative repair methods.

Cleaner and Less Invasive 

Unlike full slab replacement, which requires heavy machinery, slabjacking uses specialized equipment that is typically mounted on a compact service truck. This means the repair team can park in a driveway or on a nearby street without disrupting your landscape. With a 250-foot injection hose, technicians can access almost any repair area without rolling over your lawn or garden.

The process itself is clean, with minimal dust from drilling and only trace amounts of foam residue at the injection points. This is a stark contrast to concrete demolition, which involves loud jackhammers, extensive debris, and added waste that often ends up in landfills.

Replacing a slab also requires concrete forms, a cement truck, and a lengthy installation process, often leaving behind an uneven appearance as the new slab may not match the existing sections in color or texture.

Lower Costs

Because slabjacking works with the existing structure, it’s a more cost-effective solution than complete replacement. The overall price depends on the size of the slab and the amount of material needed to fill the void underneath.

Larger gaps require more foam injection, which slightly increases the repair costs, but even so, lifting an existing slab is often half the price of full replacement. If you’re looking for a reliable, affordable, and long-lasting option, concrete leveling near you is the way to go.

Whether you’re in St. Louis, MO, or elsewhere in Missouri, choosing the best concrete lifting team ensures a smooth, efficient, and durable repair process.
