Crack Filler for Bitumen and Asphalt

Seal the crack before it becomes a pothole

In short

Water getting into small cracks is how most potholes start. Sealing those cracks early is the cheapest maintenance you can do on a bitumen or asphalt surface.

By the Permanent Pothole Solutions team · Updated 26 October 2026

Our Rubberised Crack Filler stays flexible, keeps water out and dries to a matte black finish that blends into the surrounding pavement.

See the ACF-1 vs DP-1 comparison to choose the right crack filler for your surface.

When to seal a crack

Seal cracks as soon as you see them, in dry weather, at 12°C and rising. Cracks up to 9mm take ACF-1 directly; wider or deeper cracks should be packed with sand or backer rod to within 6mm of the surface first. Once a crack has spalled into a hole, switch to Asphalt in a Bag.

Proven on a runway

Southport Flying Club used ACF-1 to seal cracks in their aerodrome runway, applying it with a simple watering can. After a successful test area they moved up to the 19 litre bucket — and Aerodrome Manager Steve Rance says he’d recommend it to anyone with cracked asphalt. Read the testimonial →

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.
