Methodology
Transparent calculation
BuildMeter converts every input to a consistent internal unit, applies the selected allowance, and rounds products up to whole purchasable units.
Deck area = outside rectangle − pool opening. Concrete volume = deck area × thickness, with allowance applied before bag rounding.
FAQ
Concrete Pool Deck Calculator questions
Does the deck need to slope?+
Pool decks normally need positive drainage, but the required slope and direction must be designed for the site.
Does this include coping?+
No. Coping is a separate material and may replace part of the inner deck edge.
Can I use average thickness?+
Yes for planning when thickness varies gradually, but separate thickened sections should be estimated independently.
