Excavation is where every project begins — and where the difference between a good contractor and a careless one shows up first. DLI has been moving earth on Long Island since 1989, and we’ve moved more than 400,000 cubic yards on a single major development.
We handle excavation at every scale: a single foundation dig for a custom home, a footing trench for an addition, utility lines run across a property, or bulk earthmoving across a 150-acre development site. Same crews, same equipment, same standard.
Our owned fleet includes Kobelco and CAT excavators, CAT bulldozers, wheel loaders, backhoes, and a full Mack and Hino dump truck fleet. Because we own our equipment, we don’t wait on rentals and we don’t pass rental markups on to you. When the schedule says we mobilize Monday, we mobilize Monday.
Every excavation job starts with a site walk. We need to see the access points, identify the existing utilities, understand the soil conditions, and figure out where the spoils are going. From there we put together a real estimate based on what we actually saw.
Every job, every scale, follows the same disciplined sequence. No surprises.
We come to you. Walk the property, understand the conditions, identify the constraints — access, utilities, drainage, neighbors.
A detailed estimate based on what we actually see — not a guess from a phone call. Every line item explained.
Equipment and crew show up when scheduled. Owned fleet means no rental-availability delays.
Site finished to spec, debris removed, ready for the next phase — whether that's our crews or someone else's.
From single-lot work to acres of bulk earthmoving — we've done it. Tell us what you're working on.
