Charlotte's clay is dense and it doesn't drain, and that shapes every dig. A footing trench cut into it holds its shape well and bears well once compacted, which is the good news. The bad news is the crawlspace and the side yard: water that can't soak in sits against the foundation, and a Charlotte drainage job means giving it a path — a French drain along the wall, a swale across the yard, a pipe to the street — and building that path with the fall to actually carry water in ground that fights it.
Old neighborhoods mean old utilities. The sewer lateral on a 1930s Elizabeth lot may be clay pipe two feet from where the record puts it; the water line may have been replaced once and rerouted; the gas service may be shallower than anything modern. We have every dig located before the bucket goes in and we hand-dig where the locate is uncertain. A trench through a Charlotte yard is as much about what's already in the ground as what's going in.
Rock shows up in parts of the city, particularly south and east, as a shelf a few feet down. It changes a footing dig from a morning to a day. We can't see it from the surface, but we can tell you where it's likely and we quote the plan for it rather than discovering it on your invoice.
Most of it is additions and drainage. Charlotte's older neighborhoods — Dilworth, Elizabeth, Chantilly, Sedgefield, Madison Park — are full of houses being extended off the back, and every extension starts with footings dug in a yard with a fence on three sides. The drainage work is the same streets: crawlspaces and side yards that never dried out because the lot was graded once, decades ago, toward the house.
