Read the guide →What’s in Asphalt in a Bag
A ready-to-use pre-mix of selected aggregates, bitumen and a co-polymer. The polymer drives curing on compaction and makes the mix adhere to itself and to asphalt, concrete, steel and wood. A high fines content (sand and cone dust) fills voids, keeping air and water out — which is why you can use up to 20% less than other products.
Choosing the right gauge
| Mix | Compacted lift | Best for |
|---|---|---|
| 5 Gauge | 12.5–20mm | Shallow repairs and fine finishes (made to order) |
| 7 Gauge | 17.5–28mm | Driveways, footpaths, shallow potholes |
| 10 Gauge | 25–40mm | All-purpose pothole and road repairs |
| 14 Gauge | 35–56mm | Deeper potholes and heavy-duty 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.
