Waterproofing refers to the procedures applied in order to protect buildings from water or humidity that may come from all directions.

The main threat to the building’s life and durability is “water”. Water leaking in the building due to rain, snow, soil moisture, ground water or through wet areas corrode the reinforcements in the buildings’ bearing parts, resulting in significant reduction of its load-bearing capacity and deterioration of the concrete integrity and cracks and breaks.

Concrete protects steel from corrosion thanks to thin film layer formed on the surface of the reinforcement. Water leak in the building leads to corrosion; it is almost impossible for buildings that have suffered from corrosion and have reduced bearing capacity to withstand a massive earthquake. Protection from such harmful effects is possible only with waterproofing.

How Does a building leak water?

A building can be long-lasting, comfortable and healthy, only if it is constructed with a correct design and protected from external factors that damage the structure.

Water is one of the most important factors affecting buildings. Water leak in the building may occur in various severities and various ways:

  • Water leak from the ground
  • Pressure water
  • Water leak through the facade
  • Through coagulation
  • Through capillary water flow

Where should waterproofing be applied?

  • Foundation and curtain walls
  • Roofs
  • Terraces
  • Wet areas
  • Viaducts
  • Tunnels
  • Pools
  • Channels and ponds

How should effective waterproofing be?

For an effective waterproofing, the proofing application should over all constructional elements from the foundation to the roof of the building. Floor coverings on the ground, balconies, exterior walls, roofs and foundation walls should be waterproofed.
