Dark Green Canvas Tarpaulin 21oz – Heavy Duty Waterproof Cotton Duck Tarp Sheet
Our dark green canvas tarpaulin is crafted from 21oz heavyweight cotton duck — the traditional choice for professional-grade covering applications where synthetic alternatives simply don't compare. This waterproof canvas tarp is naturally breathable, incredibly strong, and built to last for years of heavy duty outdoor use.
Why Choose Canvas Over Polyethylene?
While PE tarpaulins are excellent for most applications, canvas tarpaulins offer distinct advantages in specific situations. Cotton duck canvas is naturally breathable — moisture vapour can escape while rain is kept out, reducing condensation buildup under the cover. This makes canvas tarps the preferred choice for covering vehicles, machinery, antiques, and anything that benefits from airflow rather than completely sealed enclosure.
21oz Cotton Duck — Heavyweight Protection
At 21oz per square yard, this is a heavyweight canvas tarp — one of the densest natural-fibre tarpaulins available. The tight weave of the cotton duck fabric provides exceptional tear resistance, while the wax treatment enhances water repellency without completely sealing the fabric. This balance of weatherproofing and breathability is what makes 21oz canvas tarps the professional's choice.
Key Features
- 21oz heavyweight cotton duck canvas — premium natural fibre construction
- Wax treated for water resistance — repels rain while maintaining breathability

- UV resistant — handles long-term outdoor exposure without degradation
- Dark green finish — professional appearance, blends naturally into outdoor environments

Professional Applications for Canvas Tarpaulins
- Vehicle covers — lorries, wagons, trailers, classic cars and machinery that need to breathe
- Flatbed truck covers — traditional transport industry covering solution
- Agricultural use — cover produce, equipment and livestock shelters
- Military & MOD — canvas tarps are standard equipment for military applications
- Events & festivals — premium appearance for high-visibility outdoor covering
- Antiques & classics — breathable cover for sensitive items that can't tolerate condensation
Canvas vs Synthetic Tarpaulins — The Key Differences
Canvas tarpaulins are heavier and more expensive than polyethylene tarps of similar size, but they offer natural breathability, a more premium appearance, and extreme durability under heavy use. They're the correct choice for professional transport, military, and heritage applications. For lighter general-purpose covering needs, our 200gsm polyethylene tarpaulins offer excellent value.
