Before explaining what are waterproofing materials, it is necessary to explain the concept of waterproofing. Waterproofing is the process of making an object or structure waterproof or water resistant. Thanks to this process, the insulated surface or structure resists water ingress.

In buildings, waterproofing creates a barrier to prevent water passage on surfaces that have high contact with water such as foundations, roofs, and walls. Thanks to waterproofing, building surfaces are strengthened and waterproofed. In short, waterproofing is a protective measure that makes a surface water-resistant and prevents liquids from penetrating undesirable surfaces under external forces such as hydrostatic pressure and capillarity. It is possible to answer the question of what are waterproofing materials with many different products on the market. Each of these products has different usage areas. If the correct type of waterproofing material is not applied to the surfaces, the problems that will be encountered not only reduce the comfort of living spaces but also reduce the durability of the structure. For this reason, it is imperative to apply the right insulation material to surfaces that are in high contact with water.
