If part of your driveway is lifting right where it meets your home, it’s usually not random. That area tends to be more sensitive because the soil, drainage, and structure all come together in one spot.
Here are the most common reasons it happens.
Moisture changes around the foundation
The soil next to your home is constantly dealing with water. Rain runoff, sprinkler systems, and even small plumbing leaks can soak the ground near the foundation. When that soil gets wet, especially if it’s clay-heavy, it expands and pushes upward on the driveway.
Poor drainage setup
If water isn’t being directed away from the house, it often ends up sitting along the edge where the driveway meets the foundation. Over time, that trapped moisture weakens the base and causes uneven lifting.
Soil that expands and shrinks
In many areas, the soil near foundations is backfilled during construction. This fill soil is often looser and more prone to movement. When it absorbs water, it swells. When it dries out, it shrinks. That cycle can slowly push sections of the driveway upward.
Tree roots getting too close
If you have trees planted near the house, their roots may grow underneath the driveway. As they thicken, they can lift the concrete, especially near edges where the slab is more vulnerable.
Temperature differences near the structure
The area near your foundation doesn’t always heat and cool at the same rate as the rest of the driveway. That uneven expansion and contraction can add stress and contribute to lifting over time.
Improper installation near the house
Sometimes the issue goes back to how the driveway was poured. If the base wasn’t compacted well near the foundation, or if expansion joints weren’t properly placed, the concrete may not have enough flexibility to handle movement.
What to look for
You might notice a slight hump forming near the garage or where the driveway meets the house. Cracks often show up nearby, and one section may sit higher than the rest.
Why it’s worth fixing
Heaving near the foundation can lead to more than just a rough surface. It can push water back toward your home instead of away from it, which increases the risk of foundation issues over time.
What helps
Fixing the root cause is key. That might mean improving drainage, sealing joints, trimming back roots, or leveling the slab. In more serious cases, that section of concrete may need to be replaced with better base prep.
If you catch it early, it’s usually much easier and cheaper to deal with than waiting until the damage spreads.
