use of waterproofing membrane for floors

The use of waterproofing membranes for floors is widespread in the industrial segment, renovations and construction in shops and homes. The main objective of the membrane is exactly to waterproof the floor of the place, avoiding that the humidity exceeds the subfloor from one side to another.

The indication of the use of waterproofing membrane for floors can also be given not only by the fact that it provides an impermeable floor but also a tool to modify the design, colour, or any other characteristic of the place in order to carry out the renovation.

Why choose waterproofing membranes for floors instead of flooring?

Cost-effective and quick to apply in comparison to the coating makes the waterproofing membrane for floors the best option for those who want an agile application at a low cost.

However, it is essential to note that only an experienced and trained professional can indicate which is the best option for each reality to which it is exposed, such as the type of floor already installed, the appropriate type of space, among others.

Types of waterproofing

To define the best method for waterproofing slabs, it is necessary to know the types of waterproofing that can be carried out. It is important to note that each waterproofing method has different procedures and waterproofing products, and the study of each one of them will ensure that you have a better service performed and at a more affordable price. There are two types of waterproofing: rigid waterproofing and flexible waterproofing.

Rigid waterproofing

The hard sealing is recommended to be used in places where there are no large movements of the structure, mainly caused by thermal variation. Therefore, this type of waterproofing is generally used in structures such as foundations, buckets, lower water reservoirs, underground pools, elevator shafts, retaining walls, etc.

Rigid waterproofing can be applied to waterproofing products such as mortar waterproof, mortar or epoxy and polymer crystallization.

waterproofing products such as mortarFlexible waterproofing

On the other hand, flexible waterproofing is recommended for places where the structure can move without causing damage to other elements of the building. This type of waterproofing is recommended for use on slabs (solid, mixed, or pre-molded ), terraces, balconies, upper water reservoir, gardens and kitchen floors, bathrooms, and service areas. The most common waterproofing products for applying flexible waterproofing are:

  • Membranes molded-in loco: such as asphalt emulsion, asphalt solution, acrylic emulsion, oxidized asphalt, modified asphalt, elastomers (neoprene), among others.
  • Prefabricated blankets: such as elastomeric blanket (butyl / EPDM), asphalt blanket, and polymeric blanket (PVC). Among these, the asphalt and polymeric blankets stand out because they are easy to apply and have a more affordable cost when compared to other types.

Infiltrations and leaks are any homeowner’s nightmare. Caused by cracks in the pipes, damaged or unsuitable floors for wet areas, poorly executed joints, broken roofs and, of course, moisture (which can come from the floor or fall down the walls, caused by rain), they can cause serious damage to the structure the floor, the subfloor, and even the slab, in addition to generating mold and mildew, which are harmful to the health of residents, and can affect the rooms on the lower floor. In order to avoid the problem, experts argue that waterproofing systems are essential.
