Use about 5% for simple straight layouts, 10% for most projects, and 15% or more for curves, diagonal patterns, borders, or many cuts.

Four inches of compacted base may suit many pedestrian patios and walks. Driveways, weak soils, freeze-thaw climates, or drainage problems may require 6–12 inches and local professional guidance.

Multiply the project area by the compacted base depth, then add material for compaction. The default estimate adds 20% loose volume.

A consistent 1-inch bedding layer is common. Avoid using bedding sand to correct major base variations.

It is commonly used to fill joints and can reduce movement, weeds, and washout when installed according to the manufacturer's directions.

Most unrestrained patio and walkway edges need restraints to limit spreading. Existing concrete or another fixed edge may already provide restraint.

Add the compacted gravel depth, bedding layer, and paver thickness. Also plan the finished elevation and drainage slope before digging.

The count varies by paver size, style, and manufacturer. Enter the supplier's pallet quantity to get a rounded pallet estimate.

Generally no. A properly excavated, graded, and compacted aggregate base helps prevent settling, movement, and drainage problems.
