Results are estimates

Every result from a deep4sol calculator or converter is an estimate for general planning and budgeting. It is based on standard formulas, typical product sizes and the values you enter. Actual quantities, costs and outcomes can differ because of measurement errors, differences between suppliers' products, densities and coverage rates, and local prices, labour rates, site conditions and building codes.

Always check results before you buy materials, sign contracts or start work, and confirm quantities against the spec sheet for the exact product you are buying.

Not professional advice

Our Tools and content are not engineering, structural, financial, legal, tax or medical advice. Anything load-bearing or safety-critical, and any permit, financial or health decision, should be checked by a qualified professional or your local authority.

No guarantee

We work hard to keep every tool accurate and working, but we do not guarantee that they are error-free, complete, up to date or always available. To the fullest extent allowed by law, deep4sol is not liable for any loss arising from your use of, or reliance on, the Website or Tools, including over-ordering or under-ordering materials, cost overruns or project delays.

The full terms are in our Terms of Use.
