Waterproofing is the process by which an object is made water-resistant – that is, it is unaffected by water and does not let it penetrate into it. Waterproofing can be seen on many objects – electronic devices and even clothes – but the most common application of waterproofing is no doubt in the construction sector. The process of waterproofing can be especially seen in areas that are underwater or are under constantly humid or wet conditions; accordingly, underwater tunnels or underground constructions are one of the most common examples for waterproofing.

However, the process of waterproofing can be seen in more common locations too. Home roofs, walls and basements are often waterproofed to combat the degradative effect of moisture. Accordingly, most homeowners will be asked in the construction process if they would prefer roof waterproofing or any other form of waterproofing. The necessity of waterproofing is dependent on one single factor mainly: the climate of your locality.

As was mentioned at the very start, waterproofing is more common in areas which are wet or underwater; accordingly, you should waterproof your home (and apply rising damp treatment as well) if you live in an area that features high levels of humidity or precipitation, as these can quickly result in the wearing away of certain parts, such as your roof or walls. Tropical locations frequently feature high humidity and precipitation – especially areas that coincide with the tropical rainforests or monsoonal areas of the world – and so do coastal locations and areas located on the windward side of mountainous regions. Furthermore, if you have an underground basement, you might also need to consider the soil conditions: soils which are waterlogged, or if the area has a high water table (i.e. the groundwater level of the area is not too far deep, but shallow), will mean that waterproofing the basement is a good idea.

Whilst waterproofing your home may be a costly affair, you should understand that it is a one-time application that needs small, regular maintenance every once in a while; conversely, supposing you have not waterproofed your home, what you will be facing after a few years will be cracked walls and mouldy patches, as well as a leaking and decaying roof, which will be very expensive to repair (or might need an entire overhaul or replacement). Thus, the question of whether you should or should not waterproof your home is to your personal preference if you live in the drier regions of the world; however, it is a necessity if you live in the wetter areas of the world. Most contractors will often recommend the process in both cases, but it is often better to be aware of the needs of waterproofing your home or any other building.
