Sunken Porch Slab Lifting
Sunken porch slab lifting raises a dropped porch or stoop slab where irrigation, roof runoff, or fill settlement has left the landing lower than the adjacent walkway or home edge. It applies to poured concrete porch slabs at Chandler homes where a tipped landing collects water and creates a step at the door.
Small injection holes are drilled through the settled porch slab and polyurethane foam or cementitious mudjacking material is injected beneath it to fill the void and produce a controlled lift, with elevation checked against the walkway and the home. The lift is brought up gradually so the landing lines back up with the surrounding surface.
The entry is restored to a safer, better-aligned landing with a reduced trip edge and clean patched injection points, preserving the existing slab rather than demolishing and repouring the porch.
