Getting Water Off the Pavement
Grading and drainage work keeps water from sitting on, running along or soaking under asphalt. In a hilly city like Waterbury, where streams run down both sides of the valley to the Naugatuck River, a driveway often sits right in the path that storm runoff wants to take. Water that crosses or follows a driveway washes out edges, softens the base and feeds the freeze-thaw cycle that opens potholes. Fixing the water is often what makes the next paving job last.
Common problems we see
- Runoff from the street pouring down the driveway into the garage
- Water running along one edge and washing it out
- Puddles that turn to ice patches in winter
- Downspouts emptying onto the pavement
- A driveway acting as a dam across a natural drainage line
Solutions
Regrading: reshaping the base and surface so water crosses the driveway to a safe side instead of running its full length. Angi lists yard leveling at about $1 to $2 per square foot.
Asphalt berm or wedge curbing: a low asphalt curb along an edge that channels water to a planned outlet and protects the edge from plows and tires.
Swales: shallow grassed or stone-lined channels beside the driveway that carry water past it.
Trench drains and catch basins: a grated channel across the bottom of a driveway, or a basin at a low point, piped to daylight or a drywell where allowed.
Culverts: a pipe under the driveway where it crosses a drainage line. Angi lists driveway culverts at about $1,500 to $5,000.
Rules about runoff
You cannot simply send your water onto a neighbor's property or into the street without checking local rules. Work in the street right-of-way is controlled by the city or town, or by Connecticut DOT on state routes. We check what applies before designing a discharge point near the road.
Doing it with paving
Drainage work is easiest and cheapest when it is done along with a new driveway or overlay, since the base is already open. If your driveway is still in good shape, many fixes, like a berm, a swale or a trench drain at the bottom, can be added on their own.
What to watch for
Walk your driveway during a heavy rain. Note where water comes from, where it goes and where it pools. That ten minutes tells us more than anything else at the estimate.
Ice and safety
Puddles on a sloped driveway freeze into ice patches. Removing low spots, keeping roof runoff off the pavement and sending water across rather than down the driveway reduce winter ice.

Drainage installed, usually with paving or repairs.
4. Check
We confirm the water now goes where it should.

Grading & Drainage Questions
Water from the street runs down my driveway into the garage. What helps?
A raised apron or a crown at the top, and a trench drain across the bottom in front of the garage, are the common fixes. We look at the slope and the street before recommending one.
What is an asphalt berm?
A low, rounded asphalt curb placed along a driveway edge. It guides water to a planned outlet and protects the edge from washing out.
Do I need a culvert under my driveway?
If your driveway crosses a ditch or natural drainage path, yes, or it will act as a dam. Angi lists culverts at about $1,500 to $5,000.
Can drainage be added without repaving?
Often. Berms, swales and trench drains can be added to an existing driveway that is in good shape.
