Hansville: A Hole or Sunken Spot Opened Up in My Yard

Why this happens in Hansville

Start with a leaking water service line washing out the trench. The most common cause on a sunken trench line. Around Twin Spits and Point No Point the housing dates from 1950s beach cabins expanded over decades, which makes this the likeliest answer to sinkhole or sunken spot.

Then a collapsed or separated drain line. Old clay tile or crushed corrugated pipe lets water wash soil into the pipe and away. We've seen it near Point No Point more than once, usually on a mix of materials from decades of additions.

Don't overlook an old dry well, cesspool or septic component. Older properties have forgotten structures that eventually cave. On Hansville properties from 1950s beach cabins expanded over decades it comes up more than you'd think.

Before you call

At Point No Point, Twin Spits and Driftwood Key the sand and the high water table mean leaks never surface and trenches fill as they're dug, so we locate carefully from the PUD meter or the shared main and bring pumps.

First steps for sinkhole or sunken spot near the Greenway: do the meter test. Note whether it appeared after rain or in dry weather. Keep everyone off it and mark it. Then call; the rest is a locate through till and roots on the Hansville Road uplands, not guesswork.

What happens next

When it's the buried line, the fix in Hansville is underground water leak detection: we repair, if you want us to, confirm and mark through gravel at Point No Point at the marked spot on wooded parcels along Twin Spits Road, and trace the line. Probe rods and marking and the mini excavator ride on the first trip so it's finished the same visit.

Driftwood Key, the Greenway, Foulweather Bluff: near any of them, sinkhole or sunken spot gets the same crew and the same equipment. About forty minutes to the north tip, day or night, with the mini excavator on the trailer for Point No Point and Twin Spits cabin lots.
