A vertical edge between sidewalk slabs can catch a shoe, wheelchair or snow shovel. Sidewalk lifting addresses the height difference by raising the low slab rather than grinding away a large amount of concrete or replacing an otherwise sound section.
Common causes of uneven sidewalks
Soil may settle beneath the slab, water may erode supporting material, or tree roots may change the elevation of nearby sections. The correct repair begins with identifying which slab needs to move and where the finished walk must drain.
The lifting process
Small access holes are placed strategically in the low slab. A masonry slurry is pumped below it under controlled hydraulic pressure. The technician watches slab movement and stops when the transition and drainage are improved. Holes are then patched.
Residential and municipal applications
Sidewalk lifting can help homeowners, property managers, associations and municipalities correct multiple hazards while preserving existing concrete. It is particularly useful when the slab surface is still in good condition.
