Drainage Networks

Moving massive volumes of storm water off a developed site safely requires a precisely engineered network of underground utilities and surface structures. Our heavy equipment crews specialize in the installation of heavy-duty reinforced concrete pipe, high-density polyethylene culverts, and precast concrete catch basins designed to capture immediate surface runoff. We meticulously calculate pipe slopes, laser-level trenches, and shoot invert elevations to guarantee optimal gravity flow across the entire utility network. Proper installation of these underground systems ensures that water drains quickly and efficiently away from finished parking lots, paved roadways, and structural building foundations. We bed the pipes in the correct aggregate and compact the trench backfill in strict lifts to prevent future sinkholes or pavement failures above the utility lines. By integrating robust curb and gutter systems with these underground pipe networks, we provide a permanent drainage solution that protects the massive financial investment of your commercial development.

Erosion Control

The moment heavy machinery strips surface vegetation from a parcel of raw land, the exposed topsoil becomes highly vulnerable to severe erosion. TD Craft Grading deploys a multi-layered defense system of Best Management Practices to lock the soil in place and filter sediment before it can leave your property boundaries. Our field teams install high-performance silt fencing along the perimeter, build temporary sediment basins, place rock check dams in drainage swales, and roll out tailored erosion control blankets across steep slopes. Proactively stabilizing active work zones with temporary seeding and hydro-mulching prevents muddy runoff from contaminating local streams, creeks, and protected wetlands. Maintaining strict control over sediment runoff keeps your active project fully compliant with state environmental inspectors and prevents expensive work stoppages or municipal fines. We constantly monitor and maintain these temporary erosion measures throughout the grading process so that your site remains secure during unpredictable heavy rain events.

Stormwater Basins

A complete site development package must account for the long-term impact that increased pavement and impervious rooftops have on the surrounding municipal watershed. We construct specialized stormwater detention and retention basins that act as engineered holding zones for heavy floodwaters. Heavy excavators carve out these custom ponds to capture peak runoff during intense rain events, allowing the system to slowly release the collected water at a controlled pace to prevent downstream flash flooding. Depending on your specific civil blueprints, we build dry detention basins that drain completely between storms or excavate permanent wet retention ponds that double as aesthetic neighborhood features for residential subdivisions. TD Craft Grading ensures that the structural earthen walls, concrete emergency spillways, and protective rip-rap channels are built exactly to the engineering specifications. Building these high-capacity basins correctly ensures your development safely manages its own stormwater footprint long after the heavy equipment leaves the site.
