Cómo funciona esta calculadora
Pavers per m2 = 1 / [(paver length + joint) x (paver width + joint)]. Pavers = round up(patio area x waste factor x pavers per m2). Base and sand volumes reuse the gravel formula (area x depth x density) at their own depths. Edging pieces = round up(perimeter / edging piece length).
Ejemplo resuelto
A 4 m x 3 m patio (12 m2, 10% waste = 13.2 m2) with 400 x 400 mm slabs and a 3 mm joint needs about 79 slabs, a 10 cm sub-base layer, a 5 cm sand bedding layer, and edging pieces for the 14 m perimeter.
Suposiciones a comprobar
- This combines the whole patio project (pavers + base + bedding sand + edging) in one result, following the same combined-output pattern as the fence calculator, rather than a bare paver-count tool.
- Base and bedding depths are common defaults (10 cm compacted sub-base, 5 cm sand bed) - both are editable, since sub-base depth depends on ground conditions and traffic load.
- Grouting/pointing material between pavers is not included - only the base, bedding sand, and edging.
