Waterproofing your home is one of the best investments you can make. A fully sealed low pitched metal roof, flat roof or concrete slab keeps water outside the building where it belongs, protecting your roof structure, walls, ceilings and electrical wiring from the damaging effects of damp and moisture.
If you’ve decided to take action and waterproof your home, you may be wondering what type of substance professional contractors use during the process. There are two main types of waterproofing applications in use today, with many brands and varieties to choose from – we take a look at what they are and how they work.
The two types of waterproofing applications
To keep your home free of leaks and damp, your waterproofing has to do one of two things: prevent water from penetrating your roof, or trap the water and make sure it doesn’t get further than the surface.
Scientists call these two types of substances hydrophobic and hydrophilic. Here’s what it means:
- Hydrophobic literally means ‘scared of water’ – these waterproofing applications create a barrier that causes water to slide off your roof. A well-known waterproofing substance of this type is bitumen, which is always pitch black in colour.
- Hydrophilic substances are just the opposite – they attract water droplets and store them in crystals found in the waterproofing coating. Acrylic waterproofing applications are examples of this type.
Derbigum – the latest waterproofing technology
One of the leading waterproofing applications available in South Africa is Derbigum. This special form of bitumen is hydrophobic, sealing the roof or slab that it’s applied to and preventing water from entering the structure of your home or other building.
Derbigum’s special features include UV resistance (which prevents it from cracking in the sun and letting water in), and a double layer of protection. Taken together, these two features provide an excellent water barrier.
Keeping your waterproofing in tact
An excellent layer of waterproofing is the best protective coating for your roof or slab – as long as you keep it maintained. Your waterproofing contractor to ensure that no cracks or leaks develop should carry out regular inspections.
