Concrete Contractor in Bronx, Brooklyn, Queens and Manhattan
Driveways, sidewalks, patios, foundations, and more. Strong concrete work that stands the test of time.
Concrete Contractor
Licensed Concrete Contractor Serving All Four Boroughs
Concrete either lasts thirty years or cracks in two, and the difference is almost always base preparation, reinforcement and control joints not the mix itself. Alliance General Contracting NY Inc pours driveways, sidewalks, steps, slabs and foundations across the Bronx, Brooklyn, Queens and Manhattan with compacted sub-base, proper steel and joints cut before the slab decides where to crack on its own.
Sidewalk work in New York City is governed by the Department of Transportation, which specifies slab thickness, scoring pattern, cross slope, expansion joint placement and curb-cut detailing. Property owners who hire someone unfamiliar with those specs often end up re-doing the flag after a DOT inspection. We build to the published standard the first time.
Every concrete contractor project starts with a free on-site estimate and a written scope. We are based at 2362 Westchester Ave, Bronx, NY 10462 close enough to the whole Bronx to respond quickly, and working daily in Brooklyn, Queens and Manhattan. Call 718-737-2143 or email info@alliancegeneralcontractingny.com to get on the schedule.
