Question 1

How much does a cubic yard of sand weigh?

Accepted Answer

Dry sand weighs approximately 2,500-3,000 pounds per cubic yard depending on type. Concrete sand averages 2,700 lbs/yd³, play sand about 2,400 lbs/yd³, and fill sand about 3,000 lbs/yd³. Wet sand is significantly heavier.

Question 2

How deep should paver bedding sand be?

Accepted Answer

Paver bedding sand (the layer directly under pavers) should be exactly 1 inch deep after screeding. The aggregate base layer beneath should be 4-6 inches for pedestrian areas and 6-8 inches for vehicular areas. Do not use more than 1.5 inches of bedding sand.

Question 3

What type of sand should I use for pavers?

Accepted Answer

Use concrete sand (also called sharp sand or coarse sand) for the paver base and bedding layer. For filling joints between pavers, use polymeric sand which hardens when wet and prevents weed growth and insect intrusion.

Question 4

How much sand for a sandbox?

Accepted Answer

Fill a sandbox 12-18 inches deep with play sand. A standard 8x8 foot sandbox at 12 inches deep needs about 2.4 cubic yards or approximately 3.2 tons of sand. Always use non-toxic play sand that has been washed and screened.
