Dive into the Types of Waterproofing Membrane
Waterproofing membranes come in a variety of forms, mainly differentiated by their material composition and application method. Let's delve into the three most common types:
Liquid Applied Membranes
Liquid applied membranes are highly elastic and flexible waterproofing systems, applied onto surfaces in liquid form and eventually hardening to create a rubber-like protective layer. These membranes have a great ability to bond firmly to almost any surface type, making them a popular choice for waterproofing roofs and balconies.
Sheet-based Membranes
Sheet-based waterproofing membranes are pre-formed and installed onto surfaces using an adhesive. They are usually made of rubber, plastic, or bituminous material, and are known for their high resistance to puncture and tear. Sheet membranes are ideal for use in underground structures and flat roofs.
Cementitious Waterproofing Membrane
The cementitious waterproofing membrane is manufactured from a blend of cement, sand, and special additives. Known for their easy application and cost-effectiveness, they are widely used in internal areas such as bathrooms, kitchens, and basements.
An Insight into Waterproofing Membrane Installation Procedures
The process of installing a waterproofing membrane varies depending on the type of membrane and the surface it will be applied to. Following is a general step-by-step guide:
- Start with a clean surface - It’s important to clean the area where the waterproofing membrane will be installed. Any dust or debris can hamper the membrane's adhesion, reducing its effectiveness.
- Application of the primer - After cleaning, a primer is applied to the surface. This helps in creating a perfect bonding surface for the membrane.
- Once the primer has dried, the waterproofing membrane is applied over the surface. In the case of sheet-based membranes, adhesive is used to stick the membrane to the surface. The liquid membrane is spread using a brush, roller, or spray.
- Once the membrane is applied, it needs to be left to dry for a stipulated time. Always refer to the manufacturer's instructions for specific drying times.
Remember, proper installation is crucial to ensure the maximum effectiveness of the waterproofing membrane. Therefore, it's always advisable to have the installation carried out by certified professionals.
