Tri-State Construction is a union concrete contractor offering a variety of cast-in-place services around the New Jersey Tri-State area. We specialize in large poured-in-place flatwork, both slab on grade and slab on metal deck. We also have completed projects involving heavy civil work, poured-in-place foundations, structural slabs, retaining wall systems, and post tensioned slabs. Tri-State has ACI-certified finishers that provide the highest quality of work. We have our own safety program that meets or exceeds OSHA standards and is continually updated to meet any circumstances on our projects. Regardless of the size or nature of the project, Tri-State works to ensure that each step of the construction process is completed carefully and successfully.
