Various types of waterproofing membranes


Waterproofing Membrane is an essential building component that helps protect the structural integrity and inhabitants of a building. It is a necessary element in all types of buildings. The membrane prevents water from penetrating the foundation and into the underlying structures.

There are various types of waterproofing membranes that can be used for different applications, each with its own unique advantages and disadvantages. The type of membrane to use will depend on the need and requirements of the structure, as well as the environment.

The most common type of waterproofing membrane is sheet based, which comes in rolls that are unrolled and laid onto a firm surface. The sheets are then joined together using blowtorches and a hot tar based adhesive.

Another method of installing a waterproofing membrane is by spraying the liquid over a substrate. This method does not involve laps or welds, and can be applied to any shape or size.

Elongation and Tear Resistance: The membrane should be strong, flexible, elastic, and tear-resistant, so that it can cover cracks and runs along with the building. It should also be able to stretch over the cracks that might develop in the future, if the building is subjected to movement.

Abrasion and Corrosion Resistant: The membrane should be able to withstand constant foot and vehicle traffic as well as the weather. It should also be chemically inert with respect to its environment within the building.

In addition to these key aspects of a waterproofing membrane, there are other factors that must be considered when choosing the best solution for your structure. These include compatibility, abrasion resistance, and UV stability.
