Installing a Paver Patio
Pavers are a versatile and durable choice for patios, driveways, and walkways. Success lies in proper base preparation and ensuring you have enough material for cuts.
Layer Structure
- Subsoil: Compacted natural soil.
- Geotextile Fabric: Optional but recommended to separate soil from gravel.
- Gravel Base: 4-6 inches of compacted crushed stone (road base).
- Bedding Sand: 1 inch of coarse sand to provide a smooth leveling bed.
- Pavers: The visible surface blocks.
- Polymeric Sand: Swept into joints to lock pavers together and prevent weeds.
Waste Factor
Simple rectangular patios might only need 5% extra for waste. However, curves, angles, or complex patterns can increase waste to 10% or even 15%. This calculator defaults to a safe 10% margin.
