Cover the crop. Keep the flexibility.
Engineered fabric grain buildings for Ontario producers and handlers — sized to your flat-pile volume, built on a pony-wall foundation and installed turnkey by one Ontario team.
Flat storage that keeps every option open.
On-farm flat storage gives producers room to hold a crop instead of splitting it across bins on a schedule dictated by the elevator. A fabric grain building pairs a galvanized steel frame with an inert membrane — no rusting roof deck dripping condensation onto the pile — and a clear span so the loader, auger cart or conveyor can work the full floor.
- →Pony-wall and slab system designed and built in-house
- →Doors and openings sized to your loading equipment
- →Stamped engineering for any Ontario snow and wind zone
- →Membrane warranty terms confirmed in the issued documents
Corrosion-Resistant Envelope
Galvanized frame and inert membrane hold up to grain dust, fertilizer residue and chemical exposure without a rusting steel deck overhead.
Drive-Through Access
No internal columns. Endwall doors sized to your truck, loader or auger cart for fast loading and clean-out.
Naturally Lit Interior
Daylight through the membrane lets operators see the pile and equipment without an overhead lighting array.
Flexible Bay Layouts
Internal divider walls separate crops, varieties or fertilizer so one footprint does more than one job.
Crop volume first. Dimensions second.
A grain building is sized by what it has to hold and how it gets loaded — not by picking a width off a price list. These are the inputs we use before any dimension is quoted:
- →Crop and annual volume you want covered in flat storage
- →Peak pile height and the angle of repose for that crop
- →Pony-wall height, which sets how much of the footprint actually holds material
- →Loading equipment — auger, conveyor, truck or loader — and the clearance it needs
- →Whether the building is split into bays for more than one crop or for fertilizer
- →Aeration, ventilation and drying plans for the stored crop
Send those numbers and we will come back with a building size, a foundation approach and a preliminary budget range. Preliminary figures are for budgeting only — final pricing follows engineering, site conditions and the configuration you select.
Get a preliminary project budgetThe wall does as much work as the roof.
Everything a grain building has to survive happens at the base: pile pressure against the wall, equipment contact at the opening, and moisture at the slab edge. We design the slab, the pony wall and the arch bearing detail as one system, then pour it and build on it with our own crews.
- →Wall height set by the pile depth you need contained
- →Slab and apron graded so runoff is controlled, not chased
- →Base plates and anchors selected for a dusty, corrosive environment
- →One contract from excavation through membrane tensioning
What we walk through before drawings start.
Drainage and runoff
How wash-down water and precipitation move off the apron so it doesn't pool at the wall or track toward a ditch or well.
Apron and approach
Truck queuing, turning radius and auger-cart clearance at the opening, planned before the door is placed.
Foundation type
Slab thickness, pony-wall height and the bearing detail where each arch lands, matched to pile depth and equipment loads.
Approvals
Building permit drawings for your municipality and any agricultural zoning conditions that apply to the site.
The apron, drainage and loading routine are what determine whether a grain building works day-to-day. We plan them with the building rather than after it.
Different operations, different priorities.
Cash-crop producers
On-farm flat storage that keeps the crop under one roof instead of splitting it across bins, with room to grow the operation.
Grain handlers and elevators
Commercial-scale flat storage with bay divisions and equipment clearance sized to a working handling schedule.
Mixed grain-livestock operations
A single building that stores feed grain alongside equipment or bedding, laid out around how the farm actually runs.
Fertilizer and input storage
Bays engineered for the corrosive environment of bulk fertilizer, separated from grain where a mixed operation needs it.
