The service of waterproofing in civil construction is essential to ensure the durability and integrity of the structure. This process reduces the chances of problems caused by infiltrations, such as the proliferation of fungi, bacteria, mold, paint peeling and even more serious damage that can compromise the entire building structure.
A waterproofing consists of sealing or sealing certain surfaces to protect them against the damaging effects of moisture. This process must be carried out from the initial stage of the work, that is, in founding. In this way, it is possible to guarantee a longer useful life to the structure, avoiding excessive maintenance expenses.
To learn more about this type of service, read this article to the end. In it, we will show you how to correctly apply the products and the types of waterproofing available for construction. Check it out!

Waterproofing Resin for Structured Flexible Polymer Mortar
There are two types of waterproofing: the rigid and the flexible. The rigid system does not accompany the movement of the structure and must be used on surfaces that are not exposed to climatic variations, soil movement, or subject to Trincas and cracks, such as wall plinths and baldrame beams.
In the flexible system, on the other hand, it is possible to extend and absorb cracks, following the surface. For this reason, it is recommended for places exposed to adverse weather conditions, which may suffer from moisture and infiltration, such as terraces, slabs, water reservoirs and balconies.

Thus, all water drainage points in drains and floors must be closed, leaving about 5 cm of water. After 72 hours, it must be checked for runoff and a decrease in level.
In addition, it is essential to follow the rules established by the Brazilian Technical Standards Association - ABNT. TO NBR 9574/2008, for example, determines the requirements and recommendations related to the execution of the services of waterproofing, so that the minimum building protection conditions against moisture and infiltration are followed.
