Exterior Drain Line Repair in Kingston, WA

Drainage in Kingston

A failed drain often shows as a sudden pressure drop at the house after a storm. We've dug clay tile out near White Horse and flattened corrugated from under drives on long gravel driveways through fir; both got solid pipe on grade through roots and the odd boulder off Miller Bay Road to a rebuilt outlet, and the surface back.

We've seen a driveway that keeps settling in one spot on long gravel driveways through fir near Lindvog Road and a break that never surfaces in winter by Highway 104. Both times the line was 400-foot poly lines under gravel drives, the ground was outwash near Appletree Cove, and the fix was exterior drain repair done once.

Outlet first. With hardpan saturated from November to May under long gravel driveways through fir, a drain can't rely on infiltration; it needs daylight downhill, a storm connection, or a sump. Exterior drain repair starts by finding that outlet, because without one there is no drain.

A sudden pressure drop at the house on ferry-town lots near Highway 104 with a yard drain that never empties is a collapsed line until proven otherwise. We find the failure in roots and the odd boulder off Miller Bay Road, replace that run, and set a cleanout so nobody has to guess next time near Miller Bay Road.

Ground and water in Kingston

Kingston's till plateau holds water, and the Appletree Cove and Miller Bay shoreline lots take runoff from above. On a line that has failed twice already it may mean pulling a new continuous HDPE line with the mini excavator, which is often cheaper than the third and fourth spot repairs would be.

We bring the mini excavator, pumps, solid and perforated PVC and pop-up emitters and outlet on the first exterior drain repair trip. Trenches in hardpan saturated from November to May are opened to grade, not scraped by eye, and shoreline lots on Miller Bay goes back when the drain is in near Lindvog Road.

What to expect

Three steps carry most of the weight on shoreline lots on Miller Bay: remove and replace, cleanouts and outlet, find the line and the failure. Near Highway 104 that has meant working pop-up emitters and outlet around beach deposits along the cove and copper and galvanized near the terminal; the sequence doesn't change, the hours do.

Near Appletree Cove the exterior drain repair scope is usually set by beach deposits along the cove more than anything, with 1970s polyethylene on acreage second and access across wooded acreage along South Kingston Road third. Solid and perforated PVC rides along regardless.

1970s-to-1990s acreage with a newer core near the ferry left Kingston with 400-foot poly lines under gravel drives on long gravel driveways through fir. In outwash near Appletree Cove the first sign is a driveway that keeps settling in one spot, sometimes a break that never surfaces in winter, rarely a puddle, which is why exterior drain repair starts by listening.

Where we work

Whether the exterior drain repair job is near Highway 104 or out by Appletree Cove, the response is the same: up Highway 3 and across on 104, solid and perforated PVC and pumps on board, and a crew that finishes wooded acreage along South Kingston Road before it leaves.
