From slab-on-grade flatwork to post-tensioned high-rise decks, Tri-State self-performs every scope on this page — with one union crew, one in-house BIM team, and one safety program holding it all together.
From flatwork on a retail site pad to a post-tensioned hospital tower, we self-perform every step of the concrete process. Each capability below is fully in-house — no daisy-chained subs, no schedule gaps between scopes.
Large-format slab-on-grade flatwork with ACI-certified finishing for warehouses, retail pads, distribution centers, and industrial floors at any scale.
Explore Cast-in-Place →Poured-in-place foundations and pile caps engineered for high-rise loading, heavy civil work, and mat slab applications.
Explore Foundations →Reinforced and post-tensioned slabs, columns, and beams for hospitals, casinos, hangars, and high-rise residential towers.
Explore Post-Tension →Elevated structural slabs poured on composite metal deck for multi-story commercial, healthcare, and institutional builds.

Explore Heavy Civil →Two more capabilities that don't sit alongside the others on a price sheet — they're how we run every job we win.
3D pour models, takeoffs, shop drawings, CAD layout files for total-station robots, and early-issue RFIs that keep the field moving.
Explore BIM →Internal safety standards that meet or exceed OSHA — site-specific plans, daily JHAs, and continual updates based on field experience.
Request our safety record →Multi-story commercial, healthcare, and institutional projects rely on slab-on-metal-deck systems for clear-spanning floors with predictable performance. Tri-State coordinates with steel erectors and rebar suppliers to keep the pour cycle on schedule.
We handle embedment placement, edge form treatment, mesh and bar reinforcement, and finishing — flat enough for FF/FL specs where required, with control joint planning that respects deck geometry.
Typical applications: office buildings, healthcare facilities, university buildings, mixed-use residential towers, parking structures.
Retaining systems are part site work, part structural — and we handle them as a single scope. Our crews form, place, and finish cantilever, gravity, and counterfort walls for road embankments, parking structures, ramps, and storage facilities.
We've poured site walls for marine terminals, salt sheds, recreation facilities, and large industrial pads — coordinating waterproofing, drainage, and architectural finish requirements with the GC's site team.
Typical applications: highway / road embankments, parking structure perimeters, salt & bulk storage, basement walls, ramps and grade transitions.
The same three principles run through every scope above.
Foundations, walls, slabs, columns, and finishes — all in-house. No daisy-chained subs, no finger-pointing, no schedule gaps between scopes.
Our BIM team models pour plans, generates shop drawings, produces total-station layout files, and surfaces RFIs early so the field never waits on coordination.
An internal safety program that meets or exceeds OSHA, refined for every site we work on. Site-specific plans, daily JHAs, and ongoing training.
