A sinking or uneven basement floor can be more than just an eyesore. It may be a sign of soil settlement, erosion beneath the slab, poor compaction, or moisture-related issues under your home. As the concrete settles, cracks can form, water may begin pooling, and the floor can become difficult to use safely.
At Jacksonville Contracting Co Inc, we help Maryland homeowners restore settled basement floors using proven concrete lifting solutions. Depending on the project, we may recommend traditional mudjacking or polyurethane foam lifting to stabilize the slab and raise it closer to its original position without the cost and disruption of replacement.
Most basement floor settlement occurs because the soil beneath the slab can no longer properly support the concrete above it. As the supporting soil shifts or erodes, empty spaces develop and the slab begins to settle.
Common causes include:
If left untreated, settlement can continue and potentially create larger structural and drainage concerns.
If you’re experiencing settlement in other areas of your property, we also repair garage floors, driveways, sidewalks & walkways, steps, and provide foundation repair solutions throughout Maryland.

We are about to do some hardscaping and improvements on our home but wanted to make sure our cracked and uneven patio was level. I contacted Jacksonville Contracting and Mitchell came out right away. Estimate was very fair. They were able to get us scheduled within our time frame and the guys were efficient,friendly,and did a great job.They found cracks that were 2-4” so thankfully i called them when I did. We would not hesitate to hire them again. Their prices are competitive and they are very professional!![]()

Found this company by accident and they did not disappoint. Prompt , very reasonable on price and professional! Would use them again and highly recommend to anyone who needs concrete work. For us it was adding concrete to existing pool deck that had settled over many years. Thanks Mitchell and team !!!![]()

We have a concrete front porch with several gaps from erosion that was sagging in places. Jacksonville contracting was able to fill the gaps and level off our front porch and sidewalk. They did a nice job and unlike a lot of other contractors cleaned up after themselves. They did all the work without any supervision from my wife or myself making the scheduling a dream! We couldn't be happier with the results and the service! Great job!![]()

My insurance company cited my porch for being unsafe so I asked them for recommendations and they recommended Jacksonville Contracting. They were absolutely the best contractor I have worked with in a long time. Extremely quick responses to emails same day, fair pricing, always kind in explaining the good, bad and results to expect. The kindness of Mitchell Shinnick was beyond what I have ever received and I am so thankful I was referred to him! He was very empathetic as well. I wish he could take on other home improvement projects!![]()

Many homeowners don’t realize their basement floor is settling until the problem becomes obvious. Addressing settlement early can help prevent more expensive repairs later.
Common signs include:
If you notice any of these warning signs, it may be time to have the floor professionally evaluated.
We use a simple, proven process designed to lift and stabilize settled concrete without removing the existing slab.
Small, strategically placed holes are drilled through the concrete so we can access the voids and weak areas beneath the slab.
Mudjacking material or polyurethane foam is pumped beneath the concrete to fill voids, stabilize the base, and raise the slab.
Once the concrete is stabilized, the access holes are patched, the work area is cleaned, and most surfaces can be used the same day.
Replacing a basement floor can be expensive, messy, and time-consuming. Concrete lifting often provides a faster and more affordable solution.
Benefits include:

Limited Lifetime Warranty On Helical PiersIn many cases, yes. Concrete lifting can often restore a settled basement floor without the cost and disruption of replacement. The best solution depends on the condition of the slab and the cause of the settlement.
Settlement is commonly caused by poor soil compaction, erosion, moisture changes, or voids beneath the slab. If structural settlement is also occurring, our foundation repair services may be recommended.
Jacksonville Contracting offers both traditional mudjacking and polyurethane foam lifting. We evaluate each project individually and recommend the method that makes the most sense for the specific conditions.
Sometimes. While many basement floor issues involve only the slab, settlement can occasionally be related to larger structural concerns. We can evaluate whether helical piers or other foundation repairs may be necessary.
Many basement floor lifting projects can be completed in a single day, depending on the size and complexity of the repair.
Yes. In addition to basement floors, we repair garage floors, driveways, pool decks, porches & patios, and sidewalks & walkways.
