2. Not Professional Advice
Nothing on this Website is engineering, architectural, structural, construction, legal, financial or other professional advice, and using the Website does not create a professional-client relationship between you and us.
Concrete work involves real safety and structural risks. Before you order materials, pour concrete or build anything, consult a qualified structural engineer, architect or licensed contractor, and follow all applicable building codes, standards, permits and regulations in your area.
3. Calculator Results Are Estimates
Our calculators generate estimates based on the values you enter and on standard formulas and assumptions. Real-world quantities can differ because of site and subgrade conditions, formwork, wastage and spillage, mix design, weather, measurement errors, rounding and local practice.
- Results are not guaranteed to be accurate, complete or suitable for your specific project.
- You are responsible for checking your measurements and inputs and for verifying every result independently before ordering or building.
- We recommend adding a suitable allowance for waste and variation, and confirming final quantities with your supplier or contractor.
- We are not responsible for any over-ordering, under-ordering, cost overrun, delay, defect or failure resulting from the use of our calculators.

Our blog posts and guides summarize general concrete and cement knowledge and may not cover every situation.
