What Is Duraflex Rubberising? A Simple Guide for Property Owners in the Western Cape

02.12.25 10:23 AM - By Louise

If you own property in the Western Cape, you already know this: sun, wind, rain, and coastal air are not kind to buildings. Roofs crack, parapets start to leak, balconies show damp marks, and before you know it, paint is peeling away like your patience and water damage damages your peace of mind. 

That’s whereDuraflex rubberising comes in – a modern waterproofing solution designed to protect your home or industrial building for the long haul, even in harsh coastal conditions. 

So, what exactly is Duraflex rubberising?

Duraflex Liquid Rubber creates a flexible, seamless waterproofing layer over vulnerable surfaces. It’s a liquid-applied synthetic rubber membrane that cures into a tough, elastic skin, forming a watertight barrier over areas such as roofs, balconies, foundations, and walkways. 

Because it is applied as a liquid, it can get into all the hairline cracks, joints, and obscure corners that traditional waterproofing systems often struggle with – much like sand getting into every single crevice after a beach day. Once cured, Duraflex Liquid Rubber becomes a continuous, joint-free coating that heroically prevents leaks, cracks, and water ingress.

In short: Duraflex rubberising solutions are what you need to waterproof your Cape Town property once and for all. 

Part of a proven waterproofing system

Duraflex isn’t just a single product – it contains a range designed to work together for reliable waterproofing: 

  • Duraflex Wash-It – a powerful, water-based, biodegradable cleaner used to prepare roofs, walls and other surfaces by removing dirt, grime and contaminants before waterproofing.
  • Duraflex Liquid Rubber – the champion of rubberising: a premium-quality liquid rubber membrane that forms the actual waterproofing layer.
  • Duraflex Rubber Seal – a flexible sealant used to seal gaps, joints and seams around details like flashings, pipes, gutters, and roof penetrations.

Duraflex rubberising thus refers to Duraflex Liquid Rubber, supported by proper cleaning and sealing with the complementary products.

Why Duraflex rubberising works so well in the Western Cape

The Western Cape climate likes to wreak havoc on buildings with its intense UV, strong winds, driving rain and, in many areas, salty sea air. Duraflex is designed with precisely this onslaught in mind. 
The following characteristics make it a perfect match for Capetonian properties:
  • High flexibility. The rubberised membrane can move with the substrate as temperatures rise and fall, reducing the risk of cracks.
  • Durability. Made from premium synthetic rubber, Duraflex products are built to withstand extreme weather conditions and ongoing exposure.
  • Broad surface compatibility. It adheres to concrete, metal, wood, plastic and more, making it suitable for a wide variety of roofs and structures.
  • Eco-conscious formulation. The range is water-based, biodegradable and low in VOCs, which makes it safer for occupants, applicators and the environment.

So, what does this mean? Fewer leaks, less maintenance, better long-term protection, and much more sanity for property owners. 

Where can Duraflex rubberising be used?

Duraflex rubberising is ideal for:

  • Flat or low-slope roofs
  • Balconies and terraces
  • Foundations and retaining walls
  • Roof repairs and overlays
  • Gutters, flashings, and parapet tops
  • Problem areas where previous waterproofing has failed

If you have noticed damp patches on ceilings, bubbling paint on parapet walls, or recurring leaks around roof junctions, Duraflex rubberising should become your best friend.
