Water Keeps Coming Up Through My Driveway
Water surfacing at a crack, a seam or the edge of a gravel or paved drive with no rain usually means a pressurized line underneath it, and the line is often not where you'd guess.
A damp stripe across the driveway that never dries. Water bubbling up at a crack in dry weather. Gravel that's gone soft in one spot and keeps sinking. A driveway is the path of least resistance for a lot of leak water, because the base under it is compacted gravel that carries water sideways, and the service line very often runs under or beside it on its way from the meter at the road to the house.
The line may be directly under the wet spot, or it may be twenty feet away with the water following the driveway base. Cutting concrete or digging gravel on a guess is expensive either way. Acoustic locating works through pavement; the ground microphone sits on the surface and finds the peak of the leak noise, and a correlator across the run narrows the break on a long drive. Then the opening is one cut or one small pit, at the break.
Once the break is exposed we repair it in PEX or HDPE, bed it in gravel, backfill in lifts and patch or re-gravel. On a long run under a paved drive that has failed before, we'll talk about pulling a new continuous line through the old route from a pit at each end, or re-routing around the slab entirely, so you never cut the driveway again.
What it usually means
The service line runs under the drive
Common on Bainbridge, Kingston and acreage lots where the drive is the straight shot from road to house. A break anywhere along it wets the base.
Water following the driveway base
Compacted gravel base carries water from a break elsewhere on the lot to a crack or an edge. The break can be a long way off.
A crushed drain line under the drive
Downspout and yard drain lines crushed by vehicles discharge into the base. Shows up during rain, not in dry weather.
A natural seep on a cut driveway
A drive cut into a bluff or hillside intercepts groundwater. No leak noise, meter doesn't move, wet all winter.
What to check first
- Note whether the water appears in dry weather or only after rain.
- Do the meter test with the house isolated.
- Don't cut or dig at the wet spot.
- Keep vehicles off a sinking or soft area.
When to call
- Water surfaces in dry weather
- The meter moves with the house isolated
- The driveway is sinking or heaving
- You want it located before any concrete is cut
The fix
When it's a buried line or an exterior drain, the fix is underground Water Leak Detection: we locate first, open the ground once, repair or replace, and put the surface back. One crew, 24 hours a day. (206) 354-9906.
What it looks like when we find it
Water in driveway, town by town
The likely causes shift with the ground, the housing era and the water utility. Pick your community.
Bremerton
The shipyard city's older galvanized lines fail quietly and show up as a wet lawn or a water bill nobody can explain.
Silverdale
The 1980s and 90s subdivision boom around the mall left thousands of polybutylene service lines that are now failing on schedule.
Port Orchard
The county seat's hillside lots and clay soils turn small leaks into slope problems, and long rural runs hide breaks for months.
Poulsbo
Little Norway's mix of century-old downtown lines and fast-draining bay-side outwash means leaks hide well and fail suddenly.
Bainbridge Island
Clay soils and 500-foot driveways make island leaks slow to surface and expensive to guess at, which is why we locate before we dig.
Kingston
Ferry-town acreage with long wooded service runs where a leak can hide under hardpan for an entire winter.
Keyport
A century-old Navy village with short lots, old lines and shoreline clay that keeps everything damp.
Tracyton
Bluff-side lots over Dyes Inlet where seeps and springs make it easy to mistake groundwater for a leak and vice versa.
Hansville
Beach cabins at the tip of the peninsula with shallow lines, high water tables and a long drive for anyone who isn't already in Kitsap.
Indianola
A century-old summer colony where shared lines, easements and bluff clay make leaks a neighborhood puzzle.
Suquamish
Two utilities, mixed-era housing and Agate Pass shoreline clay in the heart of the Port Madison reservation.
Manchester
Rich Passage waterfront lots where the service line runs downhill and every leak finds the beach.
Enetai
East Bremerton's bluff-side neighborhood where mid-century copper lines fail on slopes that drain toward the bay.
Lofall
Rural acreage between Poulsbo and the Hood Canal Bridge where well lines run hundreds of feet through hardpan.
Olalla
Well country at the south end of Kitsap where a leaking line shows up as a pump that won't shut off.
Seabeck
Hood Canal forest parcels where boulders, hardpan and long well lines make guessing at a leak an expensive mistake.
East Port Orchard
South Kitsap's 1970s and 80s subdivisions where copper and poly lines are reaching the end of their run.
Rollingbay
The northeast corner of Bainbridge where clay slopes, long drives and small community systems keep leaks hidden for seasons.
Port Townsend
A Victorian seaport where 1890s service lines sit under historic sidewalks and the gravity pipeline from the Quilcene delivers the water.
