How to use this calculator
- Enter Total crack length in ft.
- Enter Avg crack width in in.
- Enter Avg crack depth in in.
- Press Calculate. The highlighted row is your order quantity; the note beneath it translates the number into real-world terms.
Formula & constants
Crack volume = length × (width ÷ 12) × (depth ÷ 12) cubic feet; multiply by 7.48 for gallons. 100 linear ft of half-inch cracks needs about 1.3 gallons of hot-pour or cold-pour filler. Every default in the fields above is editable — when your supplier’s spec sheet lists a different density, coverage rate or price, enter that number instead. The waste and compaction allowances follow common trade practice; see our methodology page for the derivation of each formula and the standards it references.
Where this fits in the project
Paving is sequential: the site is excavated to design depth, a gravel base course is placed and compacted, hot mix is laid and rolled, and the cured surface is protected with sealcoat every 2–3 years. Run this calculator after base quantities are settled so the lift thickness sits on a stable, drained foundation.
How this connects to your project
No quantity stands alone — each material in the chain depends on the ones around it. These are the planning steps that pair with the crack filler calculator:
- Asphalt Calculator — Crack filler maintains asphalt surfaces and prevents water damage.
- Sealcoating Calculator — Cracks must be filled before sealcoating application.
- Driveway Cost Estimator — Include crack repair in driveway maintenance budget.
- Parking Lot Paving Calculator — Commercial lots need regular crack sealing maintenance.
- Asphalt Cost Calculator — Crack repair is an ongoing cost of asphalt ownership.
Frequently asked questions
Should cracks be filled before sealcoating?
Yes — always. Sealer bridges hairlines only; open cracks admit water that destroys the base in freeze cycles.
Hot-pour or cold-pour filler?
Hot-pour rubberized filler lasts 3–8 years and suits pros; cold-pour is DIY-friendly but lasts 1–3 years.
