A-Plus Lifting in Baltimore: Concrete Raising and Pressure Relief for Settled Foundations
A-Plus Lifting is a concrete-raising contractor serving Baltimore and surrounding counties, specializing in mudjacking and polyurethane foam injection to lift and stabilize settled driveways, patios, basement floors, and commercial slabs without full replacement.
What A-Plus Lifting actually does
The company addresses a specific concrete problem common in Baltimore's older neighborhoods: settled or sunken slabs that crack, create trip hazards, or allow water to pool. Rather than demolish and pour new concrete, A-Plus uses two methods to restore elevation. Mudjacking (also called slab jacking) pumps a slurry of soil, cement, and water beneath the slab to lift it back to grade. Polyurethane foam injection is a lighter-weight alternative that expands under the concrete to raise it with greater precision and less stress on surrounding areas. Both approaches cost less than removal and replacement and preserve the existing slab.
The work is local and recurring in Baltimore because the region's clay soils compact over time, foundation settling is common in rowhouses built on filled ground, and the freeze-thaw cycle accelerates concrete deterioration.
Services and pricing
A-Plus charges for mudjacking by the square foot, with most residential projects running $3 to $8 per square foot depending on how much lift is needed and soil conditions. A typical 400-square-foot driveway settling 2 to 3 inches costs between $1,200 and $3,200. Polyurethane foam injection runs higher, usually $6 to $15 per square foot, because the material itself is more expensive and the process is more precise. A 300-square-foot basement floor might run $1,800 to $4,500 with foam. Most jobs require a site visit to assess soil conditions, depth of settlement, and slab thickness; estimates are free. Work typically takes one to three days depending on project size, and the concrete is ready to use within 24 hours. Verify current pricing by phone, as material and labor costs shift seasonally.
How A-Plus compares to other Baltimore concrete options
Baltimore has several concrete repair shops. Concrete replacement companies like Empire State Concrete and local small operators will tear out and repour a settled driveway, which costs $15 to $25 per square foot for a new 4-inch slab but destroys the old surface and takes longer to cure. Choose replacement if the slab is severely cracked beyond cosmetic repair, already thin, or if you want a fresh finish. Choose raising if the concrete is structurally sound but settled, you need the job done quickly, or you want to avoid the mess and cost of demolition. Some Baltimore contractors offer both and will recommend based on slab condition; A-Plus focuses only on raising, which means less conflict of interest but also means they will not handle slabs too damaged to lift safely.
Who A-Plus suits and who it does not
This service is ideal for homeowners with settled driveways, sidewalks, or patios in Baltimore's older neighborhoods where ground subsidence is routine. Basement floors that have sunk or tilted are another common job. Property managers and commercial owners with settled loading docks or parking areas also benefit. A-Plus does not suit new construction or slabs that are already failing from poor initial installation; the company works only on slabs with adequate structural integrity. If your concrete is heavily fractured, contaminated, or so thin that jacking would crack it further, replacement is the only option.
What the first visit involves
Call or submit photos and dimensions online to request a free estimate. A technician visits the site, measures the settlement, examines soil type and slab condition, and takes photos. They explain which method (mudjacking or foam) fits your situation and why, show you where they will drill access holes, and discuss cleanup. If you approve, scheduling is usually within one to two weeks depending on weather and crew availability. On job day, the crew arrives with a pump truck, drills small holes in the concrete (typically every 3 to 5 feet in a grid), injects material until the slab reaches the target height, patches the holes, and cleans up. You walk the finished surface to confirm the raise meets your expectations.
Hours, parking, and logistics
A-Plus operates Monday through Friday, 7 a.m. to 4 p.m., with occasional Saturday availability for commercial jobs. Most work is done at the customer's home or business; the crew brings equipment on a truck and works in your driveway or yard. No parking constraints apply since you are the site owner. Weather affects scheduling; rain and freezing temperatures delay work because the injected material needs stable ground and time to cure. Verify exact availability and scheduling windows when you call.
A-Plus Lifting fills a practical gap in Baltimore's concrete maintenance market by offering a faster, cheaper alternative to full replacement for a common regional problem. The company's sole focus on raising means homeowners get straightforward advice without pressure to overbuy unnecessary work.
