Polymeric Paver Joint Sand Bag Count

bags = ceil(area x (1 + waste/100) / coverage per bag). A 400 sf patio at 75 sf per bag is 6 bags, but wide joints around large-format pavers cut the coverage to about 45 sf/bag and push it to 10. The coverage per bag comes from the product chart and drops sharply with wider joints and larger pavers; the sand is swept in, compacted, and misted. Distinct from the paver and base takeoff in paver-patio.

bags = ceil(area_sf x (1 + waste_pct/100) / coverage_per_bag_sf).

Polymeric joint-sand bag-count identity by name (area over the per-bag coverage, plus waste); first-principles arithmetic.

The bag-count arithmetic is public first-principles; the coverage per bag comes from the product chart.
