Five Methods Used for Construction Waterproofing in Seattle, WA

There are several techniques for Waterproofing in Seattle WA that are commonly used in the construction industry. When a new building is constructed, it is essential that everything from its basement and foundation all the way up to its terrace or roof be adequately waterproofed. This article takes a look at several of the most common methods for achieving this important goal.

Cementitious Waterproofing

This is generally considered the easiest method for waterproofing a building. It is used in areas that are prone to internal wetness, such as bathrooms, and uses rigid or semi-flexible type waterproofing. Since the areas being waterproofed with cementitious waterproofing are not exposed to outdoor weather and the sun, they do not go through contracting and expansion processes, allowing contractors to avoid many of the issues associated with outdoor waterproofing.

Liquid Waterproofing Membrane

A liquid membrane generally consists of a primer coat covered by two top coats applied by roller, trowel, or spray. It is a more flexible solution than cementitious waterproofing since the liquid eventually cures into a rubbery coat that can be applied outdoors as well as indoors. Keep in mind that the durability of the final product will depend on the quality of the polymer used, and order supplies from a reputable company.

Bituminous Coating Waterproofing

This type of waterproofing offers flexible protection. Also known as asphalt waterproofing, it is best suited for areas that are not exposed to sunlight. Long exposure to the sun can cause it to become brittle and fragile unless the bituminous coating is modified with polyurethane or an acrylic-based polymer for added flexibility.

Bituminous Membrane Waterproofing

This technique is popular for low-sloped roofs. It uses asphalt, polymers, and fillers to create a self-adhesive compound that can be applied over the initial torch-on membrane. Failing to add a protective membrane to this torch-on membrane can leave it subject to weathering and excessive wear and tear, so it is important to apply a protective coat.

Polyurethane Liquid Membrane Waterproofing

This method of Waterproofing in Seattle WA is used primarily for flat, commercial roofs. It offers great flexibility and durability when correctly applied, but requires extensive evaluation of the roof’s underlying concrete slab to avoid peeling and debonding over time.
