Retaining walls in Patchogue
Most Patchogue retaining wall work falls into two categories: grade correction on sloped lots north of Sunrise Highway, and low seat walls or terracing around patios closer to the village. Both start the same way — excavation to undisturbed soil, six to twelve inches of compacted crushed stone base, and a perforated drainage tile behind the wall wrapped in filter fabric.
Drainage is where most failed walls we get called to fix went wrong. A wall without a drainage path behind it holds hydrostatic pressure every time it rains, and on a Patchogue lot with a high water table that pressure does not relieve. Walls above roughly four feet generally require engineered drawings and geogrid reinforcement, and we handle that filing.
