Moreover, the materials are very easy to mix and apply for the waterproofing. There is a vast application of this kind of waterproofing as stated by the waterproofing specialists Sydney.

The most common use for this method is in the internet wet areas of the house, for example, a toilet or near the kitchen sink. If we look outside the house, it is used in water treatment plants, dams, bridges dams, tunnels, etc.

2. Liquid Waterproofing Membrane

Liquid Waterproofing Membrane

This method consists of a coating of the waterproofing material on the surface. The coating is usually done by spraying the material on the surface or using a roller, or a trowel. The main benefit this method has over the cementitious waterproofing is that the liquid layer of the waterproofing material is more flexible. The coating acts like rubber and can elongate to a huge extent. The durability is usually dependent on the manufacturer and the type of material it uses for making the liquid waterproofing. Polyurethane is one of the most used liquid waterproofing materials in the industry.

3. Bituminous Coating Waterproofing

Bituminous coating is usually made of the bitumen-based substances. The surfaces require a complete coating of this material for proper protection. It acts as an amazing waterproofing agent and a protective layer. The most common use of bituminous coating is on the concrete structures. The nature of this coating is quite flexible because of its polymer grade nature. 

The wide known application of the bituminous coating is in the areas that are not exposed to the sunlight because sunlight slowly makes it weak. In order to use it with the sun, you have to fix it with a more flexible material like acrylic polymers.

4. Bituminous Membrane Waterproofing

Bituminous Membrane Waterproofing

This waterproofing material is known for its strong performance. It is ideal for low-sloped roofs. This special thing about this membrane is that it has a self-adhesive nature. Most of these self-adhesive compounds are asphalt, and polymers but to increase the adhesion, oils, and some resins are also added. This type has a low shelf0life and the bonding strength usually decreased with time. On the layer, it has a torch which further has exposed and covered type. The exposed layer is most used because it can withstand extreme wear and tear due to weather. In order to apply the covered type, the protective layer is applied for preventing the damage of the layer.

5. Polyurethane Liquid Membrane Waterproofing

This method of waterproofing is mostly used for flat roofs and it is one of the most expensive waterproofing solutions. The area that is exposed to extreme weather can work very well with this waterproofing method. Polyurethane Liquid Membrane offers many benefits that the other methods don’t. It adds to the aesthetics of the surface and it has very high flexibility. This justifies its high cost. But one con of it is that polyurethane liquid membrane is sensitive to moisture. So before coating a surface with it, it is necessary to check the moisture content of it. If it is applied to the moist surface, the results can be devastating. You will find the membrane peel off after some time. This is a very common issue.
