A Hole or Sunken Spot Opened Up in My Yard (Rollingbay, WA)

What usually causes sinkhole or sunken spot in Rollingbay

A collapsed or separated drain line: old clay tile or crushed corrugated pipe lets water wash soil into the pipe and away. In Rollingbay that usually means lines under shared drives near Bay Hay and Feed, and the ground, clay that shifts rigid pipe, decides how far the water travels before you see it.

The second thing we rule in or out is poorly compacted backfill from an earlier dig. A trench that was dumped full and never compacted settles for years. It's common enough on sloped waterfront on Murden Cove that we never skip it.

And an old dry well, cesspool or septic component: older properties have forgotten structures that eventually cave. Less common on beach lots at Manitou Beach, but we've found it near Valley Road.

First steps on a Rollingbay property

Rolling Bay is on community systems and wells, so a locate may start at a shared meter vault, an individual meter or a pressure tank.

What you can check yourself on beach lots at Manitou Beach: keep everyone off it and mark it. Note whether it appeared after rain or in dry weather. If you get that far, we'll pick it up from there with pipe and cable locator and probe rods and marking.

How we fix it

In Rollingbay the work that follows the diagnosis is underground water leak detection, and it runs in order: listen, trace the line, confirm and mark. Copper and galvanized on Manitou Beach cabins in Bainbridge clay on the Murden Cove slopes sets the pace on long drives through second growth; the sequence doesn't change.

Our Rollingbay coverage for sinkhole or sunken spot runs Valley Road, Manitou Beach, Murden Cove, Sunrise Drive and everything between. We're based in Central Kitsap, about forty minutes via the Agate Pass Bridge, with pipe and cable locator and pumps on the truck.
