7 Gauge Mix

Driveway repair guides

Fixing a bitumen driveway yourself

Most driveway damage is one of three things: potholes, cracks, or crumbling edges. Fill potholes with 7 or 10 Gauge Asphalt in a Bag, seal hairline and small cracks with Rubberised Crack Filler, and rebuild broken edges in compacted layers. A typical single driveway pothole uses one or two 20kg bags — check with the calculator.

Because the mix is dense with a high fines content, it finishes smooth and close in texture to the surrounding seal.

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

Coverage at a glance

15kg bag/bucket ≈ 0.13 m² at 50mm
20kg bag/bucket ≈ 0.17 m² at 50mm
1 tonne bulk bag ≈ 8.7 m² at 50mm

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.
