Hillside pool piers

Anchored to bedrock. Built to last.

On a slope, the soil under a pool can creep downhill over the years. That is how shells crack and decks pull away. On hillside lots we drill reinforced concrete piers down to bedrock and tie them together with a grade beam, so the pool rests on rock instead of loose fill.

How we support a pool on a sloped lot. Drawing is illustrative, not to scale. Pier count and depth come from your site's engineering.
  1. Soils report

    A geotechnical engineer tests the site and sets pier depth before we dig.

  2. Drilled piers

    Holes drilled into firm ground or bedrock, filled with rebar cages and concrete.

  3. Grade beam

    A steel-reinforced beam ties the piers together under the pool shell.

  4. Engineered & inspected

    Stamped structural plans and city inspections before the gunite goes in.

Signature build

The raised vanishing edge

The lot sloped away from the house, so we lifted the pool onto drilled piers instead of digging into the hill. Water spills over a knife-edge weir into a catch basin wrapped in iridescent glass tile, and the whole wall lights up at night. From the deck it reads as a sheet of water meeting the sky.
