Foundation Volume & Concrete Calculator Disclaimer

​

This tool is intended for general guidance only and is based on standard assumptions for strip foundations and slab foundations commonly used in domestic construction across Scotland and the UK.

​

• The calculator provides an estimated concrete volume in cubic metres based on the dimensions you enter.

• It does not account for site-specific variables such as soil type, ground conditions, frost protection, reinforcement requirements, voids, or stepped foundations.

• The tool does not constitute engineering advice or a professional recommendation. For safety and compliance, all foundation works should be reviewed by a qualified structural engineer.

​

We recommend allowing a wastage margin (typically 5–10%) to account for spillage, over-excavation, or site variation. The optional wastage input box has been included to assist with this.

Please note:

• Final concrete requirements must always be confirmed by your builder, engineer, or material supplier before ordering.

• Houz Design accepts no liability for decisions made based on these calculations, or for any discrepancies between estimated and actual material usage.

• This tool and its outputs cannot be used in legal, contractual, or warranty-related disputes.

• We reserve the right to refuse guidance where we feel the request relates to a legal or contractual matter that should be handled by a solicitor or engineer.

• ​

If in doubt, seek professional engineering and construction advice.
