TBC Buildings & Concrete
The difference is not just how your building looks when it is finished—it is how TBC handles the concrete, framing, moisture barrier, and slab-edge details before you ever move in.
Why Go With TBC?
A building can look good on the day it is finished. TBC focuses on the material and construction decisions that customers may not see at first glance, but that matter at the slab, the wall line, and the framing connection.
TBC forms and pours the concrete pad before setting the building, then allows it to cure for at least 72 hours. That keeps the structure from sitting against dirt or concrete—both can hold moisture against wood and contribute to rot over time.
Instead of laying 2×4 purlins flat, TBC uses 2×6 purlins set vertically and secured with joist hangers. It is a deliberate framing detail you can see in the real TBC project photos below.
TBC brings this premium, higher-cost EPDM product in from another state as part of the wall-to-slab detail. It is an added material choice that separates the building from the concrete at the sill line.
TBC includes a 1-inch metal lip around the building perimeter and at inset door openings. This extra edge detail helps manage water at the slab and wall line, and it is not included on every basic building.
The TBC Standard
Every project is custom and TBC prices it for the work requested. These are the standard construction details that set the TBC approach apart from a basic build.
Start an Estimate26-gauge PBR sheet-metal panels
Large 6×6 treated posts
Vertical 2×6 purlins secured with joist hangers—not 2×4 purlins laid flat
A 4/12 roof pitch on the building
A 1/12 to 4/12 pitch on lean-tos
Concrete pad work formed and poured first, then allowed to cure for at least 72 hours before the building is set
Concrete wedge anchors and angle brackets at the posts
Premium, higher-cost EPDM sill gasket shipped in from out of state
Pre-engineered trusses on 10-foot centers
No wood-to-ground contact at the concrete and dirt line
A 1-inch metal lip around the building perimeter—an extra detail not every builder includes
Stamped engineered plans when required for permitting or requested by the customer
Framing FAQ
Both framing choices are available. TBC will explain the choice for your specific project before you build.
Wood Frame is TBC's clear first choice and the construction method we specialize in. It is our standard build, supported by the concrete-first, vertical 2×6 purlin, and joist-hanger process shown on this page. It also makes everyday use easier: the average owner can screw in a hook or add a shelf later without needing to hire a welder.
Yes. Both TBC frame options are engineered for the same applicable wind and snow loads. TBC still builds Red Iron when it fits a customer's project, but future shelves, hooks, or other attachments require welding or hiring a welder. We will talk through the framing approach, project requirements, and price with you so you can make the right choice for your building.

Roof & Framing
TBC does not use 2×4 purlins laid flat. We set 2×6 purlins vertically and secure them with joist hangers—the framing approach shown in this owner-supplied project photo.
Anchoring
TBC pours the pad first, lets it cure, then sets and anchors the building with 2×2×4 angle brackets and 1/2-inch by 4-inch concrete wedge anchors. Keeping the building off dirt and concrete helps avoid moisture held against wood.
Perimeter Detail
TBC includes this 1-inch metal lip around the perimeter as an extra water-management detail at the slab edge and wall line. It is a standard TBC step, not a detail every basic building includes.
Garage Door Opening
Garage door openings are set back with a 1-inch inset and metal-lip detail as part of TBC's standard approach to the opening.
Concrete Work
This owner-supplied work photo shows the inset garage-door opening and saw-cut layout on the concrete work.
Walk Door Opening
Walk door openings use a 1/2-inch inset and lip detail as part of the TBC standard building approach.
