Sunken slab, tilted stoop, or settled garage floor? We lift it back to level without tearing it out - most jobs are done in a single visit.
Foundation raising in Coventry, RI lifts a sunken or uneven concrete slab back to its original position by pumping material through small drilled holes beneath the concrete - most residential jobs on a single area take just a few hours, and the surface is ready to use the same day.
When a slab sinks, it is almost always because the soil underneath has shifted, compressed, or washed away - not because the concrete itself failed. Coventry's clay-heavy glacial soil and repeated freeze-thaw winters create the exact conditions that cause these voids to form over time. The good news is that lifting an intact slab costs far less than replacing it, and the results are immediate. If the settling is happening near your home's structural foundation rather than an exterior slab, our slab foundation building service covers full foundation construction from the ground up.
When a foundation shifts, the frame of your house shifts with it. If a door that used to swing freely now drags on the floor or a window that opened easily now sticks, the foundation beneath that section may have moved. In Coventry, this symptom often shows up in late spring after a hard winter of freezing and thawing.
Small hairline cracks in drywall are often harmless, but diagonal cracks running from the corners of doors or windows - or cracks that are wider at one end than the other - often point to uneven foundation settling. New cracks appearing after a wet season or a cold winter are worth having a contractor look at.
Walk around your front stoop, back patio, garage floor, or any concrete walkway and look for areas that are no longer level. A slab that has dropped even an inch on one side creates a tripping hazard and often means the soil beneath it has shifted or washed away. This is one of the most common calls we get from Coventry homeowners.
Standing water against your foundation wall or in low spots near the base of your house erodes the soil support over time. In areas near Coventry's lakes and river corridors, wet springs can accelerate this process. Catching it early - before the soil loss becomes a major void - is almost always less expensive than waiting.
We handle foundation raising using two proven methods, and we choose the right one based on what we find beneath your slab. Traditional mudjacking pumps a cement-and-soil slurry through small drilled holes to fill voids and push the concrete back up. It has been used for decades and is generally the more affordable option for larger areas. Polyurethane foam injection uses an expanding foam that is lighter, cures in minutes, and resists water absorption - an important advantage in Coventry's wet spring climate. Both methods leave only small patched holes in the slab, and you can usually use the surface the same day.
Before we lift anything, we assess the cause of the settling. A slab that gets raised without addressing the underlying drainage or soil problem will often sink again within a few years. We also look honestly at whether the concrete is in good enough shape to raise - if it is badly cracked or deteriorated, we will tell you, and we can connect you with our concrete cutting team for removal and replacement of the affected sections. The goal is a result that holds, not just one that looks good on the day we leave.
A proven, cost-effective option for larger residential slabs - stoops, patios, driveways, and garage floors.
A faster-curing, water-resistant method that suits wet climates and areas where added weight could be a concern.
For homeowners who want to understand what caused the settling before committing to a repair approach.
For properties near Coventry's lakes or river corridors where water is the root cause of recurring settling.
Coventry sits on glacial till - a mix of clay, sand, and gravel left behind by retreating glaciers. Clay-heavy soil holds water and swells when wet, then shrinks when it dries. That repeated swelling and shrinking is one of the leading causes of foundation movement in this region, and it affects homes across every neighborhood, from Coventry Center to the western end of town near Greene. Add Rhode Island's freeze-thaw winters, where ground temperatures swing above and below freezing dozens of times between November and March, and you have conditions that stress every slab on every property. Foundation settling here is not a sign of poor construction - it is a predictable consequence of the soil and climate. The University of Rhode Island Cooperative Extension has documented how glacial soil profiles across the state contribute to these seasonal movement patterns.
Properties near the Flat River Reservoir and Tiogue Lake face an additional factor: higher groundwater levels and longer wet periods in spring that erode soil support more quickly than in drier parts of town. Homeowners in these areas often see settling worsen after a particularly rainy spring. We also serve homeowners in West Warwick and Cranston who deal with similar glacial soil conditions and are looking for the same honest assessment before any repair work begins.
When you call, we ask a few basic questions - where the problem is, how long you have noticed it, and whether you have seen any cracks or water nearby. We schedule a free on-site estimate within one business day of your inquiry, not weeks out.
We walk the area with you, look at the slab and surrounding soil, and probe for voids. A thorough assessment also checks drainage patterns around the affected area. This is your chance to ask questions and get a plain-language explanation of what we found.
You receive a written estimate that breaks down the work, the method we recommend, and the total cost. If a permit is required, we note that in the estimate and explain the timeline. Never agree to work based on a verbal quote alone.
On the work day, we drill small holes, inject the lifting material until the slab reaches level, and patch the holes with concrete before we leave. For a typical residential job, the whole process takes a few hours. We walk you through the finished work and tell you what to watch for after the first wet spring or hard winter.
Free written estimate - no pressure, no phone guesses. We visit your property before quoting.
(401) 269-0420Raising a slab without understanding why it sank is a short-term fix. We assess the soil, the drainage, and the surrounding conditions before touching the concrete. You know exactly what caused the problem and what we did to prevent it from recurring - not just that we pumped something under it and left.
Rhode Island requires all contractors working on your home to be registered with the state Contractors' Registration and Licensing Board. You can verify any contractor's license at crlb.ri.gov before signing anything. We carry liability insurance and workers' compensation on every job.
Coventry winters cycle through freeze and thaw dozens of times between November and March. We select methods and materials suited to that reality - not what works in a mild climate. Polyurethane foam, in particular, resists water absorption in ways that traditional mudjacking materials do not, which matters in Coventry's wet springs.
Rhode Island requires permits for structural foundation work, and navigating the Coventry Building Department on your own adds time and stress to an already uncertain situation. We handle the permit process from start to finish when it is required. You do not make a single call to the town - we manage the timeline so there are no unexpected delays.
Every one of these points comes back to the same thing: we treat foundation raising as a diagnosis-first service, not a quick pump-and-go. Coventry homeowners who have dealt with repeat settling from other contractors come to us because they want to understand what is happening under their slab - and have it fixed in a way that holds.
When a settled slab is too damaged to raise, we cut out the affected section cleanly so it can be replaced at the correct grade.
