What Are Weatherproofing Membranes?

Weatherproofing membranes are materials that prevent the water from penetrating your house. This is a layer of special material aiming to stop the rainwater from entering your home. If you want to know more about it, keep on reading.

What’s interesting about them is that these membranes can be installed both on the interior and exterior. Their main purpose is to protect your walls from excessive moisture. Waterproofing materials consist of rubber, waterproof plastic, and coated-fabric materials.

Positive membranes are applied to the exterior of a structure. They will seal and protect your exterior walls from the harsh weather conditions. This is a crucial part of the construction process because they can protect outer structural components made concrete and steel. This is a smart investment for you to make, especially if you live in an area prone to storms, hails, and hurricanes.

Negative waterproofing membranes are installed to the interior of buildings. They will prevent water from entering your home and forming dangerous moist spots. They will definitely stop excessive moisture from entering your space but they won’t stop it from penetrating your walls. The most commonly used materials here are cement coatings and epoxy injections.

There is also the so-called blind side membrane. It is very difficult to be installed. What is interesting about them is that they are applied before a concrete structure is poured and directly on the top of the soil retention system.

Another thing you should know is that these weatherproofing membranes can be applied on surfaces below or above grade. If you want to get the best advice for your project, you will have to contact a contractor with a proven track record.
