A Croatian suite of construction calculators for concrete, foundations, roofs, masonry, flooring, drainage, and other practical jobs.

Landing page captured for the 2026-08-29 issue.

Field notes

The homepage organizes the tools by job rather than presenting one generic measurement form. Examples include concrete mix quantities by bag and mixer, plaster calculations with deducted openings and reveals, excavation volumes using compaction factors, and roof calculations for L- or T-shaped plans. The stated output model combines quantities with reserves, material mass, and dimensioned drawings; the extract does not expose the underlying calculator screens or formulas.
