Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

Why does mortar bed thickness vary?
It depends on the profile depth of the manufactured stone units being set — deeper or more irregular stone profiles require a thicker setting bed to fully embed and support the units.
How is the mortar volume converted to liters?
Volume in cubic meters is multiplied by 1,000 to convert to liters (1 m³ = 1,000 L), since mortar and other wet mixes are commonly quoted and mixed by liter or gallon rather than cubic meter.
Does this include mortar for pointing between stone units?
No — this calculates the scratch coat and setting-bed mortar beneath the veneer only. Pointing/grout mortar applied between and around the stone units after setting should be estimated separately.
