A growing gap between your driveway and garage floor may mean one slab is moving or sinking. You might notice a bump when you park, a wider opening along the garage entrance, or rainwater collecting near the joint. A small space between slabs can be normal, but a gap that keeps changing needs a closer look. At PolyCo Spray Foam, we offer concrete lifting in Louisiana to help homeowners repair sunken slabs and restore smoother surfaces without removing concrete that is still in good shape.
Is the Gap Normal or a Sign of Trouble?
Driveways and garage floors are often poured as separate slabs. A planned concrete joint gives them room to move as temperatures change. The material inside that joint can wear out, making the opening look larger even when the slabs have stayed in place. The bigger concern is a change in height, a widening space, or fresh cracks nearby. If your driveway used to meet the garage smoothly and now sits lower, slab settlement may be part of the problem. Photos from past years can help show whether the area has changed.
Soil Beneath the Driveway May Be Settling
Concrete needs firm support beneath it. If the ground was not packed well before the driveway was poured, it can settle over time. Some clay soils also swell when wet and shrink when dry. These changes can leave parts of a slab without enough support. The driveway may then drop near the garage while the garage floor stays at its old height. Our driveway lifting services can help with suitable sunken slabs. Before choosing a repair, the cause of the uneven concrete needs to be checked so the work addresses more than the visible gap.
Water Can Wash Away Support Below the Slab
Rainwater can add to the problem when it flows toward the garage or enters an open joint. A nearby downspout, clogged gutter, or low spot beside the driveway may send water where it should not go. Flowing water can carry away loose soil and leave empty spaces beneath concrete. As support is lost, the slab may sink farther. Watch where water goes during a rainstorm, without stepping into flooded areas. Fixing poor drainage may need to be part of the repair plan, since lifting the slab does not fix a leaking gutter or badly placed downspout.
Look for Changes Around the Garage Entrance
The gap itself is only one clue. A raised lip, chipped edges, or a new puddle can help show how the area is moving. You may also feel a stronger bump when driving into the garage. Take clear photos and measure the opening at the same spots over time. Note both the width and the height difference between the slabs. A growing gap does not prove your house has foundation damage. Still, new wall cracks or sticking doors along with slab movement are reasons to have the home checked by a qualified professional.
Why Filling the Gap May Not Solve the Problem
Adding the right flexible joint sealant may help limit water entry when the slabs are stable. However, joint sealing cannot raise a driveway that has dropped. Filling the opening with rigid concrete may also prevent the joint from moving as intended, leading to more cracking. A thin patch across the top does not replace missing support below the slab. The repair should match the cause: worn joint material needs different work from a sinking driveway. An inspection for concrete lifting in Louisiana can help you find out whether the slab needs lifting, sealing, replacement, or a mix of repairs.
How Concrete Lifting Can Help a Sunken Driveway
For suitable slabs, polyurethane foam injection can raise low concrete without tearing out the whole driveway. Small holes allow lifting foam to be placed beneath the slab. The foam expands, fills voids, and lifts the concrete in controlled steps. The crew checks the height and drainage slope during the work, then patches the holes. This can reduce a bump where the driveway meets the garage. However, concrete leveling in Louisiana does not guarantee that a wide horizontal gap will close. Concrete that has moved sideways or broken badly may need another type of repair.
The Garage Floor May Also Need Attention
Sometimes the driveway is stable and the garage floor is the part that has moved. Look for low spots inside, gaps near the floor edges, or cracks that have changed. Our garage floor lifting services address suitable settled garage slabs. Checking both sides of the entrance helps identify which surface needs work. The goal is to restore support and a useful slope, rather than raise the wrong slab. A concrete inspection helps guide that decision before repairs begin.
