Need help with measurements?
Slab dimensions: Measure the full length and width of your paving slabs in millimeters (or inches if using imperial).
Joint width: Measure the gap between slabs. Standard is 10mm (3/8").
Joint depth: Measure from the top of the slab to the base. Minimum 25mm for patios, 40mm for driveways.
Coverage area: Calculate the total area by multiplying length × width.
