First, what is an APP membrane, and why do I need it? APP stands for Atactic Propylene, a helpful product in any household, business place, or office. It is a waterproofing material used on concrete and low-slope roofs, answering the ‘why it?’ question. Simply put, it’s a waterproofing membrane of a kind.
In this article, we will look at different waterproofing membranes available, which type suits what and when to use them, their sizes, and their acquisition prices and places. Let us dive right in.
Types of Waterproofing Membranes
Waterproofing membranes are primarily used in foundations, bathrooms, external walls, roof decks, and other moisture-prone places.
There are five major types of waterproofing membranes. These are:
- Liquid membranes are of three types: water or acrylic-based, bituminous, and cementations. As the name suggests, they are liquid and are applied through spraying.
- Bitumen membranes – They are suitable for interior settings since they can be damaged by UV and heavy traffic.
- Rubber membranes – They are great for walls and underground surfaces.
- Sheet membranes are durable, easy to apply, and many are self-adhesive. They are a great choice in exterior settings.
Application of Waterproofing Membranes
Water, when allowed in certain places, can be destructive. Think of having a water-filled wall, attic, or basement; that’s not a nice picture. To prevent this picture, we introduce waterproofing membranes to it. The application of waterproofing membranes is an essential protection system for buildings. It can be done to the interior of a building or its exterior. Waterproofing membranes can either be sheet or liquid. Sheet membranes can either be applied by a hot torch or through self-adhesion.
In acquiring a sheet membrane, it’s advisable to consider your building’s structure. However, membranes with self-adhesive properties should come first on your list since they are easy and fast to apply and replace.
What to Look for in Making a Choice for Waterproofing Membranes
So, what should you look for when choosing the water membrane? An excellent waterproofing membrane should be strong. It should be tear-resistant and flexible. Elasticity should be a priority when shopping for waterproofing membranes. The membrane should be resistant to UV where it is to be applied on the exterior.
The APP membrane complies with all the above requirements making it the most commonly used waterproofing material. After selecting your desired waterproofing membrane, thoroughly clean the area before application. Cleaning is an excellent way to provide adhesion for the substrate. This ensures your membrane lays smoothly on the surface, which increases its grip.
Errors to Avoid When Installing waterproofing membranes
Several mistakes should be avoided when applying waterproofing membranes. They include:
- Application before completion of the structural elements- This should be a mistake to avoid. It is advisable to complete the structure before applying waterproofing membranes since this reduces the chances of tampering with and destroying these membranes in the building process.
- Uneven coating materials – The coating should be even to avoid weak spots, which may quickly become a big problem since a single tear is all it would take to grant water access to the picture.
- Poor workmanship – This can easily do more harm than good. Let the installers test the completed water membrane in your presence with a ton-load of water if they can’t make it rain!
Waterproofing membranes are a great way to protect your structure from moisture damage. They are customized per the buyer’s needs and are affordable. You can acquire them in most hardware stores. Many come with a user manual to help you with application and maintenance.
