Joints along the walk
Tool a control joint about every 3 feet, matching the width, which gives roughly 66 joints along this walk. Add an isolation joint where the walk meets the house, steps or a driveway so the slabs can move independently.
How to buy it
At 7.41 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
Slope the walk a little to one side for drainage and finish it with a broom for traction. Round the edges with an edging tool so they chip less.
