Keep the bale dry, not just covered.
Engineered fabric hay buildings for Ontario farms — sized to your bale count and stack height, ventilated by design and installed turnkey by one Ontario team.
A tarp isn't a building. A metal roof isn't always the answer either.
Hay left uncovered is exposed to weather from every direction. Hay under an insulated metal roof risks condensation dripping onto the top bale layer through every freeze-thaw cycle. A fabric hay building's breathable membrane roof avoids that condensation drip while the clear-span frame gives equipment room to stack and pull bales without navigating around posts.
- →Foundation designed to the stack weight and soil at your site
- →Doors and openings sized to your tractor or bale wagon
- →Stamped engineering for any Ontario snow and wind zone
- →Membrane warranty terms confirmed in the issued documents
Breathable Membrane Roof
No solid steel deck dripping condensation onto the top bale layer — the membrane surface is inert and breathable.
Drive-Through Access
No internal columns. Endwall doors sized to your tractor, loader or bale wagon for fast stacking and pull-out.
Naturally Lit Interior
Daylight through the membrane lets operators check the stack without running lights during the day.
Ventilation Planned With the Roof
Ridge and endwall openings are laid out around how the stack breathes, not added as an afterthought.
Bale count and stack height first.
A hay building is sized by how you bale, stack and move hay — not by picking a width off a price list. These are the inputs we use before any dimension is quoted:
- →Bale type — round or square — and the annual volume you need covered
- →Target stack height and how many bales high you plan to run
- →Loading equipment — tractor, telehandler or bale wagon — and its turning clearance
- →Whether the building also stores equipment alongside feed
- →Ventilation needs based on bale moisture at the time of storage
- →Room to work the face of the stack without backing into the wall
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 base and the airflow matter as much as the roof.
A hay building has to carry stack weight without settling and move air well enough to keep bales from heating. We design the base — compacted granular pad or concrete perimeter — and the ventilation openings as one system, then build with our own crews so there is no scheduling gap between grading and steel.
- →Base type matched to stack weight and site soil conditions
- →Grading directs runoff away from the stack, not through it
- →Ridge and endwall openings sized for the ventilation the stack needs
- →One contract from site prep through membrane tensioning
What we walk through before drawings start.
Drainage and grading
How the pad is graded so rain and snowmelt move away from the stack rather than pooling at the base.
Apron and approach
Equipment turning radius and clearance at the opening so the door isn't blocked during a busy loading day.
Foundation type
Compacted granular pad or concrete perimeter, matched to stack weight and site soil conditions.
Approvals
Building permit drawings for your municipality and any agricultural zoning conditions that apply to the site.
The base, the apron and the loading routine are what determine whether a hay building works day-to-day. We plan them with the building rather than after it.
Different operations, the same dry-matter goal.
Cash-hay operations
Covered storage that protects bales destined for sale, keeping quality consistent from cutting to delivery.
Dairy and beef producers
On-farm feed storage sized to the herd, laid out for efficient daily feeding routines.
Small-ruminant and mixed farms
Flexible bay layouts for round or square bales alongside other farm storage needs.
Custom bale and forage operators
Buildings sized for seasonal volume swings and equipment that moves bales in and out quickly.
