DAMTECH CALCULATORS
Dam Linings, Waterproofing & Water Storage Calculators
Use these practical tools to estimate dam lining area, waterproofing material, steel water tank sizing and annual water storage requirements before requesting a quote.
Use Damtech's planning calculators to estimate dam lining area, dam liner material quantities, steel water tank sizing, waterproofing area, irrigation water requirements, rainwater harvesting potential and water storage needs across South Africa. These tools help farms, mines, game lodges and commercial properties prepare dimensions and demand figures before requesting a dam lining quote.
Dam Lining Area Calculator
The dam lining area calculator helps you estimate geomembrane material for earth dams, ponds and reservoirs. Enter top and bottom dimensions, depth, side slope, freeboard, overlap and anchor trench allowances to plan HDPE or PVC dam liner material before a site inspection.
Steel Water Tank Size Calculator
The steel water tank size calculator estimates corrugated steel reservoir capacity from daily water use, backup storage days and a safety factor — useful when sizing farm, lodge or commercial water storage.
Water Requirement Calculators
Plan annual farm water demand, land-size based requirements and crop irrigation needs with our annual water requirement, water by land size and irrigation water requirement calculators. The rainwater harvesting calculator estimates catchment yield for tank or lined dam storage planning.
Waterproofing Area Calculator
Use the waterproofing area calculator to estimate bitumen or torch-on material for roofs, reservoirs, channels and water-retaining structures, including upstands, overlaps and wastage allowances.

GUIDANCE
How to Use These Estimates
These calculators provide early planning estimates only. They help you prepare dimensions, water demand and material areas before requesting a dam lining quote or site inspection from Damtech.
Final material quantities depend on site inspection, slopes, anchor trenches, overlaps, waste, access and supplier specifications. Irrigation and water requirement values depend on rainfall, crop type, soil, system efficiency and seasonal demand.
Damtech can confirm requirements during quote and site inspection. For accurate dam liner material estimates, steel water tank sizing or waterproofing area calculations, send us your site photos and dimensions.

Pre-quote checklist
- Measure length, width and depth
- Confirm existing liner condition
- Estimate annual water demand
- Note access constraints
- Take clear site photos
- Request a site-specific quote
These calculators provide preliminary planning estimates only. Final material quantities, water storage requirements and installation recommendations must be confirmed by Damtech after reviewing site dimensions, site conditions, access, material specifications and project requirements.
Calculator results are not engineering designs, legal water-use approvals or final quotations.
FAQ
Calculator FAQs
Common questions about dam lining calculators, water storage estimates and quote preparation.
- Can I use the dam lining calculator for a final quote?
- No. It provides a preliminary estimate only. Final material quantities depend on site dimensions, slopes, anchor trenches, overlap, wastage, access and material specifications.
- What measurements do I need for a dam lining estimate?
- You should collect the top length and width, bottom length and width, depth, side slope information, freeboard allowance and any anchor trench requirements if known.
- Can the calculator estimate water requirements for a farm?
- Yes, the page includes planning calculators for annual water demand, land-size based water requirements and irrigation water requirements. Final values depend on crop type, rainfall, soil conditions and irrigation efficiency.
- Can Damtech help if my dam is already leaking?
- Yes. Use the leaking dam repair assessment tool to prepare basic information, then request a site-specific inspection or quote.
- Are calculator results engineering designs?
- No. The calculators provide planning estimates only and do not replace engineering design, water-use approval, supplier specifications or a formal Damtech quotation.
