How the Calculation Works
Capacity: volume = length × width × height for a rectangular tank, and π × radius² × height for a cylindrical one. One cubic metre holds 1,000 litres, so a tank 2 × 2 × 1.5 m holds 6 m³, which is 6,000 litres.
For rectangular tanks: floor = length × width, walls = 2 × (length + width) × height, ceiling = length × width.
For cylindrical tanks: floor = π × radius², walls = 2 × π × radius × height, ceiling = π × radius².
When dimensions are unknown, the calculator estimates dimensions from capacity or typical tank sizes. The result should be treated as a planning estimate only.
FAQ
For full internal waterproofing, yes. If the work is floor and walls only, uncheck ceiling.
Exact dimensions are the most accurate. Capacity-only and no-measurement modes are estimates.
No. This page calculates area. Use the waterproofing material calculator after getting the area.
