Foundation and slab work covers the concrete that everything else in a building sits on: footings, basement walls, monolithic slabs for garages and additions, driveway and patio slabs, and repair work on foundations that have cracked, settled, or let in water. In Gastonia's clay-heavy soil, this trade leans as much on drainage and grading know-how as it does on finishing concrete smooth. Get the prep wrong and the pour looks fine for a year, then starts telling on itself with cracks, heaving, or a door that won't close right.
What to look for before you hire
Ask how the crew handles soil prep: compaction, gravel base depth, and vapor barriers for slabs that will have flooring on top. Find out whether they pull permits and schedule inspections themselves, since foundation work almost always requires a local inspection before backfill. Get a written scope that spells out rebar or wire mesh size, concrete strength (PSI), and slab thickness, not just a lump-sum price. And ask what happens if they hit unexpected soil conditions or old debris once digging starts, because that's common on older Gastonia lots and it changes the price.
How we score contractors here
Our rankings weigh licensing and insurance, the consistency of past work (repeat patterns in reviews around cracking, timeliness, and cleanup), how clearly a company communicates scope and pricing, and whether they stand behind the pour with a workmanship warranty. The full method is on our methodology page.
