3 Types of Waterproofing Systems Used in the Construction Industry

Structures and buildings in Australia are required to be waterproofed. If you own a commercial building, you should know the specific areas that should be waterproofed. Areas in and around swimming pools, water tanks, roofs or terraces, decks or balconies, kitchen, bathrooms, and basements (although rarely), should be applied with a waterproofing system upon construction.

Before having your building constructed, you will need to purchase the right waterproofing materials and products. A waterproofing supplier in Australia like Waterproofing Direct can help you get what you need. Similarly, they can help you decide which waterproofing method you should use. Here are the standard waterproofing systems used in commercial buildings.

Polyurethane Liquid Membrane

Polyurethane liquid membrane is a highly flexible waterproofing product. This makes it a suitable method for areas in your building that are exposed most of the time to weathering.Its sensitivity to moisture makes it an ideal waterproofing system for flat roofs.

However, before applying this product, you must ensure that the concrete slab that acts as your building’s roof is well-dried. The membranes may de-bond and peel away if there is even a small amount of moisture on your roof. Ask your supplier for a particular grade, depending on the method of application – spray, roller, or trowel.

Liquid Waterproofing Membrane

A liquid waterproofing membrane is also flexible, although not as much as polyurethane. It is the most used kind though, due to its durability.

Like polyurethane, liquid waterproofing is applied through spraying, using a roller, or a trowel. At first, a thin coat or primer is used, topped with two more coats.

Cementitious Waterproofing Method

Any waterproofing supplier in Australia would tell you that the easiest technique is the cementitious method. You can have it mixed and applied, or you can mix it yourself.

The cementitious method is a semi-flexible type of waterproofing, perfect for areas that are not exposed to weathering and sunlight such as the toilet areas.

Waterproofing for commercial buildings is important because it also protects construction materials from accumulating moisture. Not only does it protect the structure of your building, but it also keeps away water from porous building materials.
