Pour it straight from the bag into the hole, compact it, and the polymer starts curing on impact. There is no tack coat, no mixing, and the repair can be driven on straight away.

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.
