What foundation and slab work covers
This category includes the structural concrete that everything else in a building sits on: poured footings, slab-on-grade for houses and additions, garage and driveway slabs, basement walls, and monolithic slabs for outbuildings or accessory dwelling units. In and around Charlotte, contractors also deal with the region's clay-heavy soil, which expands and contracts with moisture and is a common cause of cracking or settling when a slab isn't prepped correctly. Some crews handle new construction only, others specialize in repair, leveling, or replacing failed slabs and cracked foundations in older Charlotte neighborhoods like Plaza Midwood or NoDa where homes have shifted over decades.
What to check before you hire
Foundation work is one of the few jobs where a mistake stays buried under a house for years before it shows up as a cracked wall or a sloping floor. Ask any contractor on your shortlist about soil testing or grading experience, how they handle reinforcement (rebar size and spacing, wire mesh, vapor barriers), and whether they pull permits and schedule inspections themselves. Get a written scope that specifies concrete mix strength (PSI), slab thickness, and curing time, not just a lump-sum price. A crew that won't put those details in writing is worth a second look before you sign anything.
