Outdoor slab settlement
Water movement, soil changes, and old fill can contribute to outdoor slabs losing support. The pattern of settlement often matters as much as the amount the slab moved.
Drainage matters
A patio should not be lifted without considering where water will go afterward. The provider should review door thresholds, drains, landscaping, downspouts, and the intended slope.
Porches and steps
Porch slabs and steps can be more constrained than an open patio because walls, foundations, doors, columns, and fixed steps may limit movement. A site review is especially important.
Compare lifting and replacement
If the slab is intact, lifting can reduce demolition. If the surface is deteriorated or the layout needs to change, replacement may offer more flexibility.
