Sinkhole or sunken spot in Indianola, WA

The likely causes here

In Indianola we check a collapsed or separated drain line before anything else, because a wet spot that's just the bluff draining is how it shows up here. Old clay tile or crushed corrugated pipe lets water wash soil into the pipe and away. Ground that holds water all winter makes the signs misleading, so we confirm rather than assume.

Next: poorly compacted backfill from an earlier dig. A trench that was dumped full and never compacted settles for years. With till on the Indianola Road parcels under narrow village lanes near the dock, the symptoms can look identical to the first cause, which is why the meter test and the locate matter.

Finally, a leaking water service line washing out the trench. The most common cause on a sunken trench line. Worth five minutes before anyone digs a sandy beach shelf below the village.

What to check first

Indianola's village lines run through easements and across neighbors' lots from the 1920s summer-colony days, and the first job is tracing where the pipe actually goes.

Do this before anyone digs a sandy beach shelf below the village in Indianola: don't fill it until the cause is known. Do the meter test. It takes minutes and it tells us whether the problem is on wooded parcels along Miller Bay Road or inside the house.

The fix in Indianola

The repair side is underground water leak detection. On shared lines with no drawings that means trace the line, then confirm there is a leak in bluff clay above Port Madison where the problem actually is, then repair, if you want us to. If what we expose is 1920s summer-colony plumbing at the end of its life, we say so with the pipe in your hand.

From the Clubhouse to Miller Bay Road and out around the beach, sinkhole or sunken spot is a regular Indianola call for us. About half an hour off Miller Bay Road, and emergencies on narrow village lanes near the dock dispatch immediately, any hour.
