Sidewalks and Curbs

We pour sidewalks and curbs that are clean, consistent, and DOT-compliant. From demolition to finish work, our crews deliver safe, accessible walkways and smooth transitions. Whether it’s a storefront, municipal block, or full development, we build concrete that looks good and lasts through seasons of wear.

Sidewalk Vaults

Sidewalk vaults require more than concrete—they demand structural expertise. 4D rebuilds and repairs below-sidewalk vaults with reinforced slabs, waterproofing, and full code compliance. We handle everything from demo to DOB inspection, ensuring your sidewalk and what’s beneath it stays strong and safe.

Asphalt

We provide asphalt paving and resurfacing for commercial lots, drive lanes, and utility patches. Our crews handle grading, milling, and finish work with efficiency and attention to detail.

Civil/Sitework

Before the first footing is poured, we prepare the ground for success. Our site work services include clearing, grading, trenching, and sub-base prep for concrete or asphalt. We move quickly, coordinate cleanly, and build with your full site plan in mind, because a solid structure begins with the ground up.

Our spray-on fireproofing services protect structural steel and help buildings meet fire-resistance codes. We apply cementitious and intumescent coatings cleanly and to spec, ready for inspection. Whether part of new construction or a retrofit, our fireproofing holds the line when it matters most.
