Blog, Insulation & Waterproofing

Your home is more than just a place you go to relax. It is a shelter or, if you prefer, a safe haven for both you and your family. It might take a lot of time and finances to get your home as comfortable and desirable as you want it to be, but once you do, you are sure you will enjoy it for years to come.

The home you build should not be hampered by water at any point in time. This is why home waterproofing is a very important step to take. If not done properly or at all, the structural integrity of the home may suffer.

Aside from that, you risk putting yourself and your family at risk, as it may result in damage to valuables in the home. So, sit back and let us explain better what waterproofing is, why it is important, and the various types of waterproofing.

What is waterproofing, and why is it so important?

Basically, waterproofing is a series of steps taken to protect the building and its structures from water. Waterprrofing also reduces the humidity and dampness in the home, preventing any structural damage that may occur.

Waterproofing done at the time of construction is termed integral waterproofing. It is used mostly to cut costs and save time. Non-integral waterproofing is done after the structure’s construction is completed.

Different areas in the home usually require waterproofing. They include;

Why is waterproofing important?

There are various advantages of waterproofing, they include the following;

  • The structural integrity of the home is protected
  • The aesthetic of the home will remain intact since the paints or walls are not affected by water
  • Hygienic living condition is promoted
  • You prevent fire outbreaks
  • All furniture and other valuables in the home are protected
  • Help prevent steel rebar corrosion

Types of waterproofing

1. Liquid-based waterproofing

Liquid-based waterproofing or liquid-based membrane is a type of waterproofing consisting of liquid chemicals. These chemicals can be sprayed, applied with a roller, or troweled.

One reason this type of waterproofing is preferred is that the chemical has strong elastic properties. Therefore, it does not develop cracks if the concrete underneath swells; rather, it expands. Liquid-based waterproofing is best for surfaces like bitumen, concrete, and asphalt.

2. Cementitious waterproofing

This type of waterproofing is mostly preferred for a structure that will see a lot of water, or that is underwater. When used in a place that is dry or exposed to dry conditions for too long, it may crack, defeating the whole purpose of waterproofing. This type of waterproofing is suitable for;

  • Dams
  • Tunnels
  • Railways
  • Sewage

3. Bituminous coating waterproofing

This type of waterproofing is done by spraying bitumen over the desired surface. It then creates a thin layer that helps prevent water from entering the surface. This type of waterproofing is best for surfaces that would not be exposed to sunlight unless modified with polymers.

4. Polyurethane waterproofing

This type of waterproofing consists of two chemicals, namely, a base and a reactor. Once applied, the two chemicals form a coating over the surface. However, it becomes a main problem if it does not dry properly before it is exposed to sunlight.


Which type of waterproofing is best?

Polyurethane is by far the best type of waterproofing, however, it is best done by a professional as any error may automatically nullify the entire purpose.

What is the cheapest type of waterproofing?

Regarding price, Bituminous Coating Waterproofing is considered to be the cheapest type of waterproofing.

Conclusion – Choosing the right type of waterproofing for your home

Waterproofing prevents rusting, corrosion, and other damages that may eventually affect the structural integrity of a building. It also helps save money over time that will be spent on extensive repairs due to water damage.

Determining the best type for your building has to be looked at from various angles that might even be confusing to you. It is often advised to seek the expertise of either a contractor or an expert to get the best recommendation.
