Foundations set the schedule for everything that follows. Tri-State self-performs the full foundation scope — from footings and grade beams up through pile caps, mat slabs, and tower-supporting mass concrete pours — with the formwork capacity and engineering coordination to keep things moving.
We've poured foundations for high-rise residential, healthcare campuses, manufacturing facilities, and heavy civil infrastructure across the Tri-State region. Currently underway: foundation walls and mat slab at the Cooper Tower in downtown Camden.
Built for the building, planned for the schedule.
The foundation systems we routinely self-perform.
Continuous mat foundations for towers, deep foundations under heavy load, and mass concrete pours requiring thermal control planning.
Cast-in-place caps over driven, drilled, or auger-cast pile foundations, tied into grade beams and column starter rebar.
Isolated spread footings, continuous strip footings, and combined footings under columns, walls, and equipment.
Basement walls, retaining foundation walls, elevator pits, and below-grade waterproofed wall systems.
Reinforced grade beams connecting pile caps and footings, with embeds for upstream structural framing.
Equipment pads, elevator and stair pits, transformer pads, marine and infrastructure-scale foundation work.
From the excavator's last bucket to the column starter bars, Tri-State runs the foundation scope as a single self-performed package.
