Sunken Patio Slab Lifting
Sunken patio slab lifting raises a dropped patio panel back toward the adjacent surface where irrigation, drainage, or fill settlement has left one section lower. It applies to poured concrete backyard patios across Chandler where a tipped slab collects water and becomes uneven underfoot.
Polyurethane foam injection or cementitious mudjacking is used to fill the void beneath the settled patio slab and produce a controlled lift, with elevation checked against the surrounding grade and the home's edge. Small injection holes suit backyard slabs where a clean, minimal-footprint lift is preferred.
The patio is restored toward a smoother, safer surface with a reduced trip edge, improved drainage direction where the grade allows, and clean patched injection points — without tearing out and repourting a slab that still has service life.
