Fill cracks neatly across beds and borders. Choose cartridge or bag sizes for your project. Reduce waste, save money, and finish repairs confidently today.
These examples show typical garden path crack repairs. Your results depend on crack shape, cleaning, and the product label.
| Scenario | Cracks | Length each | Width | Depth | Waste | Package | Estimated volume | Estimated units |
|---|---|---|---|---|---|---|---|---|
| Stone path joints | 10 | 2.0 m | 6 mm | 8 mm | 8% | 300 mL | 0.70 L | 3 cartridges |
| Patio slab cracks | 6 | 3.0 m | 10 mm | 12 mm | 10% | 300 mL | 1.32 L | 5 cartridges |
| Planter edge gaps | 12 | 1.2 m | 5 mm | 10 mm | 7% | 5 kg tub | 0.39 L | 1 tub |
Accurate crack filling starts with identifying where movement happens. Walkways, edging stones, and patio slabs often open where soil settles or roots push. Mark active gaps, loose pieces, and areas that trap water. Cleaning and drying time strongly affect adhesion and cure. Use this calculator after you decide which cracks will be repaired, and which need structural fixing or joint redesign decisions on site for durability.
Measure several points instead of one. For length, record each crack or use an average length for repeated joints. For width and depth, take at least five readings per zone, then average. If the crack is tapered, choose the V-shaped profile to reduce cross‑section volume. Add a small edge allowance only when you plan a visible bead on both sides consistently for appearance and safer footing.
Packaging choices change cost and handling. Cartridges suit narrow cracks and precise tooling, while tubs or bags work for wider joints and bulk patching. Enter the package size from the label and a realistic unit price. The calculator converts volume to mL and mass, then estimates units. If your label provides coverage per unit, enter it to cross‑check the volume method for confidence in ordering accurately.
Waste and overfill are practical, not theoretical. Waste covers mixing losses, nozzle purging, spillage, and cleanup. Overfill covers finishing needs when you tool the surface flush or slightly crowned. For small bead work, waste can be higher due to frequent starts and stops. For deep voids, consider staged filling or backer material to reduce volume and improve performance over seasons in harsh weather on sunny days.
Results are best used to plan purchases and sequence work. Buy enough product for the recommended unit count, then keep one extra unit for touch‑ups. Schedule repairs when temperatures and moisture are within label limits. After filling, protect the area from foot traffic and irrigation until cured. Record final usage to refine future estimates for your garden pathways and share notes with your crew later afterward.
It works for narrow beads and wider joints. Enter average width and depth you plan to fill. For very large voids, use backer material or staged lifts to match the product label.
Use Rectangular for fairly straight sides, V-shaped for tapered gaps, and U-shaped for rounded joints. The shape factor reduces volume when the crack is not a full rectangle.
For clean, continuous cracks, 5–10% is common. For short segments, porous edges, or frequent nozzle changes, increase waste. Track actual usage once, then adjust your default value.
Some labels list linear coverage at a specified bead size. If you enter that value, the calculator estimates units from total length as a second check. It recommends the higher count to reduce shortages.
Yes. Select a currency symbol for display, then enter your local unit price. The calculator multiplies recommended units by unit price to show an estimated total cost.
Fill only when surfaces are clean and dry. Water and irrigation can trap moisture in the crack and weaken adhesion. Plan work during a dry window and protect the repair until fully cured.
Safety note: Follow product label directions for cleaning, priming, and curing. For structural or moving joints, consult a qualified professional.
