No extra contractor. No second crew. Building Depot designs, pours and finishes the foundation for every Megadome fabric building we install in Ontario.
Most fabric building dealers stop at the steel. We don't. Our own people grade the pad, set the forms, pour the concrete and tension the membrane — start to finish, with a single point of accountability.
That means the foundation is engineered for the building, the anchors land exactly where they need to, and you only ever sign one contract.
Full perimeter strip footings and slab-on-grade. The strongest option for permanent buildings carrying heavy loads, sidewall pressure or interior storage push-walls.
Stacked precast knee-wall blocks form a heavy mass perimeter that anchors the trusses and doubles as a push-wall for bulk material — salt, aggregate, fertilizer or grain.
Individual concrete piers anchor each truss leg. Minimal soil disturbance — perfect where the slab is gravel, sand or compacted base, and where the site may need to be restored later.
Block, conventional and pier systems are the three most common — Megadome buildings can be specified with up to nine engineered foundation types depending on soil, loading and end use.
Nine engineered foundation types. The three diagrams below show the most common cross-sections — Conventional strip footing, stacked precast Blocks, and concrete Pillars — each carrying the same steel arch on a different sub-grade detail.
Our team grades, surveys and tests the pad before a single form goes in. We confirm bearing, drainage and frost depth on every project.
Forms, embeds, rebar cages and anchor bolts are set by our own crew — matched to the engineered drawings stamped for your building.
Pump trucks, vibration, finishing and curing — done in-house. We pour foundations year-round across Ontario, including cold-weather hoarded pours.
Once cured, the same crew sets steel directly onto the foundation. No scheduling gaps, no finger-pointing between trades.
Every foundation is stamped and sized for your soil, snow and wind loads — not pulled from a catalogue.
Cold-weather hoarding, heated cure blankets and additives let us pour straight through an Ontario winter.
One contract. One crew. If anything moves, we're the only number you have to call.
