Torch-On Waterproofing Solutions

Torch-on waterproofing is ideal for flat roofs and large commercial surfaces in Gauteng. It costs R200 to R400 per square metre and lasts 8-10 years.

This bituminous membrane system offers excellent value. Professional application creates a seamless barrier that withstands South Africa’s harsh UV exposure.

These solutions create flexible, seamless membranes for irregular surfaces. They reach difficult areas but require proper surface preparation for best results.

Cementitious and Crystalline Systems

Cementitious waterproofing costs R100 to R200 per square metre. It’s economical for basements, foundations, and water-retaining structures.

These systems penetrate concrete, forming crystalline structures that block water. They offer exceptional durability and can self-heal minor cracks over time.

Polyurethane systems are pricier but excel in high-moisture environments. They create elastic membranes that bridge structural movements and cracks.

Acrylic waterproofing is more affordable and popular for homes. Both offer excellent UV resistance, crucial in South Africa’s climate.

At Handyman Johannesburg, we recommend polyurethane for high-traffic areas. Its durability justifies the higher cost for balconies and exposed decks.

The existing surface condition plays a crucial role in determining overall costs. Deteriorated surfaces or failed previous waterproofing can require extensive preparation work. For a typical terrace house, surface preparation can add R1,500 to R4,000 to your budget.

Preparation might include removing old materials, treating mould, or repairing cracked surfaces. Thorough preparation is essential for achieving long-lasting waterproofing results.

Project Complexity and Accessibility

The project’s complexity influences the labour cost for waterproofing per sqm. Standard flat surfaces with easy access typically attract lower rates. Intricate designs or hard-to-reach areas command premium pricing.

Labour costs generally range from R120 to R450 per square metre. Projects requiring specialised equipment or work in confined spaces naturally incur higher costs.

Material Quality and Guarantees

The quality of waterproofing materials impacts both immediate costs and long-term value. Premium products typically cost 20% to 50% more than standard options. However, they offer superior durability, extended lifespans, and enhanced protection.

When comparing waterproofing company rates per sqm, consider the warranty period offered. Quality materials with substantial guarantees may represent better value despite higher initial costs.
