What Are the Different Types of Waterproofing?

Which type of waterproofing is best for you?

This is a question that is often asked of contractors who provide waterproofing services. It’s best to know what’s out there before making a decision along with the guidance of your contractor.
The most common types of waterproofing used in the industry are:

1.   Cementitious waterproofing

This type of waterproofing is normally used to seal indoor areas exposed to water, such as bathrooms.  Since this waterproofing type is only semi-flexible and even somewhat rigid, it is mainly used indoors where exposure to the elements, and hence expansion and contraction is not an issue

2.   Liquid waterproofing membrane

This is a thin membrane coating which consists of a primer coat and one or two top coats. It is a lot more flexible than cementitious waterproofing, but its durability is very much dependent of the type of polymers used in its fabrication.

3.   Bituminous coating
This coating is made of a thin layer of bitumen (similar to asphalt). It’s not very resistant to sunlight as it gets quite brittle, and therefore should not be exposed to it unless it is combined with other more flexible materials, such as polyurethane polymers.

5.  Polyurethane liquid membrane

Polyurethane membrane is a durable and flexible type of membrane that can be used on exposed roof areas.  It is relatively sensitive to moisture during application, and the moisture of the surface that it is being applied on should be considered before installation to prevent de-bonding.
