What is a sand setting bed?
The material for the bedding layer should be course concrete sand. Do not use stone dust or screenings; they do not allow the pavers to set properly and tend to break down over time. The sand should be an even 1″ thick layer. Do not compact the sand setting bed. Do not mix cement into the sand used for the setting bed or the joints between pavers, as this decreases the flexibility of the paver system.
