What Are The Different Kinds Of Waterproofing?


waterproofing products used in these cases are materials

There are several methods used to waterproof buildings. The cementitious method happens to be the easiest among them. The waterproofing products that are needed to do such work are available rather easily from companies that supply masonry products. It is also rather easy to mix them and then apply them as well. 

This method is used mostly in internal wet areas such as toilets. This type of waterproofing can be described as a semi-flexible or rigid kind. However, since the method is used mostly in the internal wet areas there is no exposure to the likes of weathering and sunlight. This means that there is no expansion or contraction in these cases.

Liquid waterproofing membrane method

As far as concrete water leak repair is concerned the liquid waterproofing membrane method is rather effective as well. Here a thin coating is used. It normally has a primer coat as well as a couple of coats of topcoats. These are usually applied by using a spray, trowel, or roller. 

They offer a greater degree of flexibility compared to the cementitious method of waterproofing. In these cases, the liquid forms a rubber-like coating on the wall. These coats can be elongated by as much as 280%.

Bituminous coating waterproofing method

As the name would suggest, the main waterproofing products used in these cases are materials that are derived from bitumen. This kind of coating is highly flexible as well. However, its flexibility and the protection it provides depend on the grade of polymerization and its overall formulation. 

The quality of fibre reinforcement also plays a major role in this particular context. Bituminous coating is also referred to as asphalt coating. They are applied the most in areas that are lower than even screed wet. As a waterproofing agent and protective coating, it is excellent.

Bituminous membrane waterproofing method

The bituminous membrane waterproofing method is also used a lot for concrete water leak repair. It is highly popular in the case of roofs with low slopes. They are known to perform well in such scenarios. This particular method employs both self-adhesive membranes as well as the torch-on membrane. 

The self-adhesive compounds are made up of asphalt, filler, and polymers. In certain cases, some oils and resins are also added so that the product can be made more adhesive. However, the issue with this kind of waterproofing is that the membrane loses its bonding properties with time and this means that it has a low shelf life.

Polyurethane liquid membrane waterproofing method

The main waterproofing products used in the polyurethane liquid membrane waterproofing method are polyurethane products. This particular method is used the most in areas where you have flat roofs. These are ones that are exposed to natural forces such as weathering. This particular method is rather costly as well. 

A great thing about it is that it offers a high degree of flexibility. However, it is rather sensitive to damp content on the surface where it is being applied. Therefore, before you go ahead with it you need to make sure that the humidity content on the solid slab is manageable.
