Install and Level the Sand Bed

What happens here

Spread a layer of paver sand or concrete sand over the compacted gravel base. Lay down screed rails (metal pipes are commonly used) at the desired depth for the sand bed. Use a long, straight edge (like a wooden 2x4) to drag across the screed rails, effectively leveling the sand to a uniform thickness. Carefully remove the screed rails and fill in the small trenches they leave behind, smoothing the area by hand.

Goal: Create a perfectly level and consistent sand bed for brick placement
