Foundations & pile caps.

Cast-in-place foundations engineered for high-rise loading, heavy civil applications, mat slabs, and mass concrete pours — coordinated from excavation through cure.

Overview

The deepest scope on the job.

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.

Applications

What we pour underneath.

The foundation systems we routinely self-perform.

A / MAT SLAB

Mat slabs & mass concrete

Continuous mat foundations for towers, deep foundations under heavy load, and mass concrete pours requiring thermal control planning.

B / PILE CAPS

Pile caps

Cast-in-place caps over driven, drilled, or auger-cast pile foundations, tied into grade beams and column starter rebar.

C / FOOTINGS

Spread & continuous footings

Isolated spread footings, continuous strip footings, and combined footings under columns, walls, and equipment.

D / WALLS

Foundation walls

Basement walls, retaining foundation walls, elevator pits, and below-grade waterproofed wall systems.

E / GRADE BEAMS

Grade beams & tie beams

Reinforced grade beams connecting pile caps and footings, with embeds for upstream structural framing.

F / SPECIALTY

Specialty foundations

Equipment pads, elevator and stair pits, transformer pads, marine and infrastructure-scale foundation work.

Self-Performed Scope

What's included in a foundation bid.

From the excavator's last bucket to the column starter bars, Tri-State runs the foundation scope as a single self-performed package.

  • 01
    Excavation coordinationHand-off coordination with the site contractor, base preparation, and dewatering as required.
  • 02
    Formwork & bracingEngineered forming systems sized for the lift, with bracing for hydrostatic and impact loading.
  • 03
    Rebar placement & embedsHeavy mat reinforcement, dowels into pile caps, column starters, plates, anchor bolts, and waterstop.
  • 04
    Concrete placementPump or crane-and-bucket placement with mix design and thermal control coordinated for the pour size.
  • 05
    Mass concrete thermal monitoringSensor placement, thermal logs, and curing strategy on mass placements where heat-of-hydration is a concern.
  • 06
    Hand-off to structureVerified survey, embed certification, and a clean hand-off to the structural framing trade above.
