How do I calculate the amount of expansive mortar needed?

The dosage is calculated by determining the total rock volume (Length x Width x Height) and applying the recommended hole spacing. Our calculator also accounts for hole diameter (32mm-50mm) to provide a precise KG requirement.

Does the SCA calculator include a safety allowance?

Yes, our tool provides both a theoretical net requirement and a 'Recommended Purchase' value which includes a 10% safety allowance to account for site-specific waste and over-drilling.

How does rock hardness affect the SCA dosage?

Harder materials like Granite or Quartzite require closer hole spacing (approx. 0.3m-0.4m), which increases the total amount of expansive mortar needed per cubic meter compared to soft rocks like Sandstone.
