What are the types of waterproofing for walls?

Waterproofing is important if you want to extend a building’s longevity. Water can seep into the concrete, damaging your home’s internal and external walls. You can avoid large-scale repair works later by taking the right waterproofing decision during construction. Thanks to innovation, you can avail yourself of several waterproofing solutions for your home.

When it comes to construction, concrete slabs, walls, roofs, ceilings, etc., may require waterproofing depending on the usage of the space. To make waterproof cement for construction, you can add certain chemicals or additives to the mix to enhance the final product’s water-resistant capabilities.

Waterproofing types

Cement manufacturers include admixtures to the concrete during the mixing process to improve the water-repellent abilities. Following are the waterproofing types which you can use while building your home:

Cementitious waterproofing

Cementitious waterproofing uses cement-based polymer, creating a strong and durable moisture barrier for concrete structures. It also provides breathability on the surfaces to resist mould or mildew. This waterproofing is helpful in water treatment plans, parking structures, concrete roofs, etc.

Liquid waterproofing

You can spray and paint liquid waterproofing membranes on the walls. They form an elastic membrane providing water resistance to the walls. Compounds such as strong cement for house construction, silicone, polyurethanes, acrylic copolymers, resins, etc., can be used for liquid waterproofing.

Bituminous coating

Bitumen is a sticky and highly viscous petroleum, also known as asphalt. You apply the bitumen-based coating to roofs, pavements, and other concrete structures. Note that prolonged exposure to the sun may not retain the bituminous well.

Admixtures

Admixtures are materials other than water, aggregates, and cementitious materials added to a concrete mix to enhance its properties, be it hardening, durability or waterproofing.

What is the waterproofing process?

Whenever you want to apply waterproof cement for construction to your walls at home, you should ensure the surface is clean and free from oil, loose materials, and dust. Fill any cracks with concrete to ensure no gaps on the surface. If required, apply a primary waterproofing coat to prime the structure, followed by multiple coatings.

How long does it last?

Typically, quality waterproofing should last for at least 10 years. Hence, you need to invest in top-quality waterproofing solutions. Poor-quality waterproofing does not last long, and you may need to spend more money fixing it. Waterproofing costs depend on the method, roof size, structure complexity, location, etc.  Whatever method you choose, a ponding test can determine how effective the waterproofing is.

Conclusion

Any area in your home continuously exposed to water needs waterproofing. These include the bathroom, roofs, balconies, certain sections of the kitchen, and basements. You can make your concrete water-resistant using less water when making the mixture. Alternatively, add admixtures to the concrete mix to improve its water-resistant properties.
