Thickness for walks

Four inches is the usual thickness for a residential walk that only sees foot traffic. Where the walk crosses a driveway, pour that section at 6 inches, since car tires will cross it.

Joints along the walk

Tool a control joint about every 6 feet, matching the width, which gives roughly 32 joints along this walk. Add an isolation joint where the walk meets the house, steps or a driveway so the slabs can move independently.

Truck, bags or a short load

At 14.81 yards, a ready-mix truck is usually easier than bags. Long walks are often poured in sections, so ask the plant how long the truck can wait and whether there is a short-load fee.

Slope and finish

Give the walk a slight cross slope, around 1/4 inch per foot, so water sheds to one side. A light broom finish across the walk gives grip when it is wet.
