Grading & Excavation in Fort Worth, TX

Grading and excavation covers everything that happens to a site before pavement goes down: removing old material or bad fill, cutting and filling dirt to reach a buildable elevation, setting positive slope and the flow line so water leaves the site on purpose, and compacting the subgrade so it can carry an aggregate base. We scope each piece separately during the site walk, since a small driveway job might need only light grading while a lot rebuild needs full excavation and subgrade stabilization. Each piece gets its own line on the written quote, so you know exactly which part of the sitework you're paying for.

There's no flat per-square-foot number for grading the way there is for laying asphalt, because the cost is driven by cut-and-fill volume — how much dirt has to move, how deep the excavation runs, and whether bad material has to be hauled off site. A small regrade bundled into a driveway build costs far less than excavating and stabilizing a lot with failed fill underneath, and access for equipment factors in too. We quote it in writing after walking the site, itemized separately from the paving that follows, so the dirt work never gets buried inside a single lump-sum number.

Most grading and excavation phases run 1 to 3 days, depending on cut-and-fill volume and access for equipment. Where the scope is just base and subgrade preparation on a site that's already close to grade, it typically runs 0.5 to 2 days on its own. Larger commercial excavations near the I-35W South Freeway corridor, where more material has to come out and be hauled away, land toward the longer end of that range.

The flow line is the actual path water follows once it leaves a roof, a driveway, or a lot — the low route it will always take, whether you've designed for it or not. Cutting the flow line means shaping the ground so that path leads somewhere useful, usually to a street, a swale, or a storm inlet, instead of to a foundation or a neighbor's yard. On South Fort Worth's flat, low-lying ground near Benbrook Lake and the Trinity floodplain, an undefined flow line is the single most common reason a site ponds after every rain.

Grading to daylight means shaping a slope so water reaches a point where it can exit the property on the surface — daylight — rather than being trapped against a retaining structure or pooling in a low spot with nowhere to go. It's most relevant on sites with any elevation change, where a poorly graded slope traps runoff instead of releasing it. We design to daylight wherever the site allows it, since a surface exit is simpler and more reliable long-term than relying on underground drainage alone.

It depends on the city and the scope. Forest Hill routes driveway and paving-related work through its Permits & Applications department, while Benbrook issues permits through its Building Inspections division — two different cities, two different desks, and different thresholds for what triggers a permit versus what doesn't. Larger commercial excavation and drainage work is more likely to require review than a small residential regrade. We identify the correct permitting path for your address during the site evaluation, before any equipment mobilizes.

Yes. We regularly grade and stabilize a site — correcting drainage, fixing a low spot, removing bad fill — without any paving attached, especially on properties where a homeowner or property manager is fixing a standing-water problem before deciding what surface goes on top. It's also common the other direction: bundled into a driveway or lot build so the drainage and paving scope are quoted and scheduled together. Either way, the grading work is priced and itemized on its own line.

South Fort Worth sits on expansive clay that swells when wet and shrinks hard through the dry season, moving the ground several inches a year in some spots. An uncompacted or poorly stabilized subgrade moves with that clay, and whatever pavement sits on top of it cracks and heaves along with it. We compact the subgrade and aggregate base in lifts, checking density against a Proctor target under ASTM D698 or D1557, so the ground underneath stays put even as the clay around it keeps cycling.

Paving over an ungraded or unstable site doesn't remove the water or soil problem — it just buries it under fresh asphalt for a season or two. Water still finds its way to the same low spot, still softens the base from underneath, and the surface above it starts rutting, alligator cracking, or potholing well before a properly graded job would. On South Fort Worth's low, water-collecting ground, skipping grading is the most common reason we get called back to fix a driveway or lot that's barely a year old.

Excavation is removing material — digging out old concrete, bad fill, saturated dirt, or anything that has to come off the site before work continues. Grading is shaping what's left, or what's brought in, into the correct elevations and slopes so water moves where it's supposed to and the subgrade sits at the right depth for the base course above it. Most jobs need both in sequence: excavate down to sound material first, then grade that surface to the drainage plan before compaction starts. A site with good existing soil might skip excavation almost entirely and go straight to grading; one with failed fill needs both, in that order.
