Repair and level concrete before a small problem gets worse
Concrete does not need to go the moment it cracks or sinks. A lot of the time we can save the slab you already have, and that spares you the cost and the mess of a full tear out. Our crew repairs and levels concrete all over Washington. We raise a sunken driveway apron that scrapes your bumper, and we flatten a front walk that has heaved into a trip hazard by the steps. The first thing we do is figure out what caused the damage, because a patch smeared over a slab that is still moving will just crack again within a season. So we find the cause and fix the root of it. Then we bring the surface back to level and seal the concrete, so water stops working its way in and pulling the crack wider over time.
Most concrete trouble in DC starts with the ground, not the slab sitting on top of it. Our soil holds a lot of clay, and clay swells when it soaks up heavy summer storm water, then shrinks back down when the dry weeks come. Add the freeze and thaw of a cold Potomac winter, and a slab resting on a weak or washed out base will settle, tilt, or crack right down the middle. So we dig into the real reason the slab moved in the first place. We wash out or fill the empty voids underneath it, lift the concrete back to where it belongs, and firm up the base so the fix holds instead of sinking again the next wet season. That is the difference between a repair that lasts and a patch that fails by spring.
- We find what made the slab move and fix that cause, not just skim a patch on top and hope it holds.
- Slab lifting that raises sunken concrete back to level and fills the empty voids below, with no full tear out.
- Crack repair and joint sealing that shuts out water, so the freeze and thaw of a DC winter cannot pry the damage wider.
- Uneven sidewalks, aprons, and steps brought back flush, so nobody in the house or on the block catches a toe.
- A straight read on when a slab is worth saving and when a fresh pour is honestly the smarter call for you.
Not every slab is worth saving, and we will tell you straight when it is not. Sometimes the concrete is crumbling all the way through, or the base under it has washed out for good, and in those cases a lift will not hold. A fresh pour is the honest answer there. But plenty of slabs across Washington just need the empty voids filled, the level brought back, and the open cracks sealed. When that is the case, a good repair costs less and takes far less time than ripping the whole thing out and starting over. We walk the concrete with you, point out what we see and why it happened, and give you a plan that fits the real damage rather than the biggest invoice. In a lot of Washington neighborhoods, a leveled slab reads like new once the seams are cleaned up and the surface is sealed back over.
Do you have concrete that has cracked, sunk, or lifted anywhere in Washington? From Capitol Hill to Petworth to the blocks near Rock Creek Park, we would be glad to take a look. Call us and we will set a time to walk the slab and give you a straight plan.
