Types Of Waterproofing Methods In Construction

Waterproofing is the most important step in construction to ensure that your building will stand the test of time. The more thought and research you put into waterproofing as a method, such as cementitious or sheet membranes, the longer your building will last. This is done by applying waterproofing methods or materials to the exterior walls and roofs of the building. There are several types of construction, which depend on what material or method you use to achieve it:

Elastomeric Liquid Membranes

Elastomeric liquid membranes are made of rubber and are used in waterproofing walls. They are flexible, which allows them to be applied on both horizontal and vertical surfaces. Elastomeric liquid membranes do not require the surface to be cleaned before application, but it is important to make sure that all joints between two different types of materials (such as brickwork) are completely sealed before applying the membrane.

Elastomeric liquid membranes have a high permeability rating (the ability of a material to allow water vapor transmission through its structure), making them ideal for use with walls that contain cavities, such as those in traditional masonry construction. They can also be used for cavity walls constructed from timber studs rather than bricks or stone blocks; however, these applications may require additional caulking around windows and doors where there is no cavity between two layers of materials (e.g., concrete).

Cementitious Waterproofing

Cementitious waterproofing is a method of waterproofing that uses cement to seal the cracks in the walls and floors. It is used in areas where there are high water tables. This method is also used in areas where there are frequent floods.

In this type of waterproofing, cement is mixed with sand or other aggregates and applied on the surface to seal it from water penetration without having to dig a trench around it or use any kind of mechanical equipment as one would have needed in conventional methods such as trenchers or pumps.

Liquid Applied Membrane

Liquid-applied membranes are a thin layer of waterproofing material that is applied directly to the surface of a building. These membranes are often used on flat roofs but can also be used in other areas where waterproofing is necessary. They can be made from different materials, including bitumen, asphalt, and rubber.

Sheet-Based Membranes

Sheet-based membranes are typically used to waterproof walls and roofs. They are commonly used for waterproofing flat roofs but can also be used for other construction projects. Sheet-based membranes are often used with other waterproofing methods, such as painting or spraying. Sheet-based membranes are usually applied over a layer of insulation like foam or plastic sheeting, which helps prevent condensation from building up on the inside of the roof or wall while preventing leaks in case water does get through the membrane itself.

Bituminous Waterproofing Membrane

Bituminous waterproofing membranes are a type of waterproofing membrane used to protect the concrete roofing system. It is a bitumen layer applied to the roof surface, providing protection against water, wind, and UV. This waterproofing method also has low permeability, which reduces the risk of leakage or seepage from inside your home or business.

Polyurethane Liquid Membrane

Polyurethane liquid membrane is a flexible waterproofing, sealing, and finishing material used for all residential and commercial structures. This material can be applied to roofing, wall cladding, and flooring. It comes with a high-quality finish, making it ideal for any construction project.


The best way to waterproof your home is by hiring the right company to help you with your project. There are many different types of waterproofing methods available in construction, so you need someone who knows what they’re doing when it comes time to make recommendations on which one will work best for their customers. Make sure they have experience working with these types of materials before hiring them because it could save money in the long run!
