Structures are exposed to water because of the conditions below;
-Precipitations such as rain and snow,
-Soil moisture and soil absorbed precipitation and utility water,
-Use of water in wet areas such as bathrooms and toilets,
-Pressurized and non-pressurized groundwater on the ground on which the building is built
Water can not be prevented from threatening the structure and comfort by the above-mentioned ways, but it can be prevented from entering the structures. The processes carried out on the surface of the building envelope are called "waterproofing" to protect the structures against water and moisture that may come from all directions.One of the most important factors that damage structures is water.Water penetrating into our buildings leads to deterioration of concrete in the carrier parts of our building, cracking and rusting of reinforcement in reinforced concrete, and their carrying capacity to decrease.
Whereas our structures are exposed to internal water in wet areas such as bathroom,sink, they are also exposed to external water such as rain,snow,soil moisture, groundwater on the ground on which the building is built.
In order to protect the buildings from water and harmful effects, the processes to keep the water out of the structures and to keep the water in the structures such as pools, drinking water tanks and ponds are called "waterproofing".Materials that provide waterproofing are called waterproofing materials. Materials used in waterproofing are gathered under three different headings according to their usage areas and properties.
-Bituminous cover : Oxidized bitumen membrane covers, Polymer bitumen membrane covers (APP / SBS added)
-Geomembrane Synthetic covers: PVC membrane, EPDM membrane, TPO membrane, FPO membrane, ECB membrane, HDPE membrane
II. Sliding Based Materials
-Cement based materials
-Acrylic based materials
-Polyurethane resin based materials and polyurea coating
III. Structural Waterproofing Materials
Waterproofing materials should be selected according to the intended use and the region to be applied; according to the water pressure in the environment, the structure of the ground, the movements expected from the building, the possible loads on the product, the climatic conditions and the details in the building
