There is no statutory licence to work as a waterproofer in South Africa, so you can start once you have the skills, the kit and a registered business. The training path most people follow is the National Certificate NQF (National Qualifications Framework) Level 2 in Waterproofing and Roof Repair, a 12-month programme run by providers such as the BMI Group Coverland Roofing Academy. Get the registrations sorted, build a torch-on and liquid-membrane kit, and price your work as a market-range estimate, because no industry body publishes fixed waterproofing rates.
How to register and get qualified
Waterproofing is an unlicensed trade, but training and a clean business setup win the better work.
- Formal training. The recognised pathway is the National Certificate NQF Level 2 in Waterproofing and Roof Repair (about 12 months), offered through the BMI Group Coverland Roofing Academy and similar providers. CETA (Construction Education and Training Authority) learnerships also cover waterproofing competencies.
- Industry body. The Waterproofing Federation of South Africa (WFSA) is the relevant association. Membership is not compulsory but signals competence to clients and specifiers.
- Manufacturer accreditation. Most membrane makers (for example Sika and similar suppliers) run applicator training. Becoming a trained, accredited applicator is what lets you offer a backed product warranty, so it is worth doing early.
- Business registration. Register a sole proprietor or a Pty Ltd (private company) with the CIPC (Companies and Intellectual Property Commission), get a SARS (South African Revenue Service) tax number, and register for COIDA (Compensation for Occupational Injuries and Diseases) once you take on workers. You only register for VAT (Value-Added Tax) once your turnover passes R2.3 million in a 12-month period, the compulsory threshold from 1 April 2026; below that it is voluntary.
Kit and start-up costs
Waterproofing is a moderate-cost trade to enter. These are approximate retail figures, so check current prices before you buy.
- Blowtorch and propane system for torch-on membranes: about R3,000.
- Roller set, brushes and squeegees for liquid systems: about R2,000.
- Angle grinder for surface preparation: about R2,000.
- Pressure washer (buy at about R4,000, or hire at first).
- Heat-proof gloves, face shield and flame-resistant overalls: about R2,500.
- Safety boots and a harness for working at height: about R2,500.
- Scaffold and access equipment: hire as needed.
A realistic launch kit lands at roughly R15,000 to R25,000. Working at height brings the OHS Act (Occupational Health and Safety Act 85 of 1993) and the Construction Regulations into play, so budget for proper fall-arrest gear from day one, not later.
What you can charge (estimates)
No South African body publishes waterproofing rates, and public data is thin, so treat every figure below as a guidance estimate that varies by province, access and substrate. Quote each job on its own merits.
- Torch-on bitumen membrane: roughly R150 to R300 per square metre, labour only.
- Liquid waterproofing: roughly R100 to R200 per square metre, labour only.
- A full flat-roof system, supply and apply: roughly R300 to R600 per square metre.
Standards and warranties
SANS 10400-L (the South African National Standard for roofs, part of the National Building Regulations) requires a waterproofing system to stay watertight for at least five years without maintenance. All flat-roof waterproofing must be done by a competent person following the manufacturer instructions, with expansion joints incorporated and the specified membrane method used. Note honestly that waterproofing warranty requirements are not uniformly regulated across every product type, so the binding terms are usually the manufacturer ones; read them and apply the product exactly as specified to keep the warranty valid.
Common mistakes
- Skipping manufacturer accreditation. Without it you cannot offer a backed product warranty, which is the single biggest trust signal in this trade.
- Cutting corners on fall protection. Most waterproofing is at height; the Construction Regulations are not optional and the fines and injury risk are real.
- Quoting a published rate. There is no published rate. Price the actual job, the access and the substrate, not a number off the internet.
- Ignoring expansion joints and substrate prep. A failed membrane is almost always a prep or detail failure, and the callback is on your time.
