1 Tonne Bulk Bags of Cold Mix
Fifty bags’ worth in one delivery
A 1 tonne bulk bag of Asphalt in a Bag holds the same mix as fifty 20kg bags and covers about 8.7 m² at 50mm compacted depth, or about 17 m² at the 25mm minimum. It’s the most practical pack for crews, farms and sites with repairs to do over months.

Sealed stock has a 12 month shelf life, so one bulk delivery can cover a whole season of repairs.

Why Asphalt in a Bag
- Permanent. Expands and contracts with the road surface, so the patch moves with the pavement instead of breaking away.
- Cures on impact. Curing is activated by compaction — tamp it or roll it and it sets.
- Bonds to anything. Adheres to asphalt, concrete, steel and even wood.
- Any weather. Apply from -26°C to 49°C, in rain, or straight into a pothole full of water.
- No tack coat. No pre-coating or priming. Open, pour, compact.
- Traffic-ready. Application is up to five times faster, and it can take traffic immediately.
