Concrete, Masonry & Foundation Calculators

Concrete is ordered by the cubic yard, and nobody wants to be half a yard short with the truck on site. These calculators turn slab, footing, column, pier and stair dimensions into yards, size footings for decks and fence posts against frost depth, and plan garage and shed slabs. The masonry set covers rebar spacing and weight, cinder block walls, brick and mortar, bond patterns, paver patio base and sand, retaining wall block and chimney flue sizing. Every page shows its formula, a worked example and a waste allowance, so you can check the math before you order.
