O que é o Paver Calculator?

Pavers are sold individually or by the pallet, and the laying pattern significantly affects how many you need — a herringbone or 45-degree diagonal pattern creates more cut waste than a simple running bond. This calculator computes pavers needed for your area, applies a pattern waste factor, and calculates the gravel base volume required for a stable installation.

You may also find the Landscape Rock Calculator, Grout Calculator, and Retaining Wall Calculator useful.

Quem usa esta calculadora?

This tool is used by homeowners laying a patio or driveway, landscapers quoting paving jobs, and concrete suppliers calculating pallet orders.

  2. Insira Area width.
  3. Insira Paver size.
  4. Insira Laying pattern.
  5. Clique em Calcular para ver os resultados instantaneamente.

Fórmula

The calculator uses the following formula:

Area = Length × Width; Pavers = ceil(area ÷ (paver_L × paver_W) × pattern_factor); Gravel = area × 0.15 × 1.8

Exemplo de cálculo

A 4 m × 3 m patio using 200 × 100 mm pavers in herringbone pattern (5% extra waste) needs approximately 660 pavers and 3.24 m³ of compacted base material.

Cálculo passo a passo

  1. Paved area: 4 m × 3 m = 12 m²
  2. Paver area (20×20 cm): 0.04 m² per paver
  3. Pavers with 5% waste: ceil(12 ÷ 0.04 × 1.05) = 315 pavers
  4. Gravel base (15 cm): 12 × 0.15 × 1.8 t/m³ = 3.24 tonnes

Erros comuns a evitar

  • Skipping or under-sizing the gravel base — leads to settling and cracking
  • Not compacting the gravel and sand bedding layers properly
  • Using paver size in metres instead of centimetres
Pro Tip: Always compact the sub-base in layers of no more than 100 mm using a plate compactor. A paver surface is only as good as the base underneath — rushing the compaction is the #1 cause of sunken, uneven paving.

Perguntas frequentes

What depth of base material do I need under pavers?
For pedestrian patios: 100 mm compacted gravel + 30 mm bedding sand. For driveways: 150–200 mm compacted gravel + 30 mm bedding sand. The calculator uses a 150 mm base depth by default.

What is the waste factor for different paving patterns?
Running bond (standard): 5% waste. Herringbone (45°): 10–15% waste. Diagonal (45°): 15–20% waste. Complex patterns with multiple sizes: 15–20% waste. The calculator applies pattern-specific factors.

Do pavers need to be sealed?
Sealing is optional but recommended — it reduces staining, enhances colour, and inhibits weed growth in joints. Apply penetrating sealer 28 days after installation. Reapply every 3–5 years.

How much does a pallet of pavers cover?
A standard pallet covers 10–15 m² depending on paver size and thickness. 200 × 100 × 50 mm concrete pavers typically pack 500–600 per pallet. Always confirm coverage with your supplier.

Can I lay pavers over an existing concrete slab?
Yes — if the slab is level and structurally sound. Use a 30 mm layer of bedding sand or polymer-modified mortar. This raises the finished paving level, so check door clearances and step heights first.
