What is Waterproofing?
Waterproofing applications made with the aim of making any structure water resistant, protect the application area against water ingress and prevent possible damage caused by water, thanks to its resistant and protective structure. Thus, the insulation can be protected from the negative effects of water.
What Does Waterproofing Do?
In its most basic form, waterproofing ensures the prevention of water leaks and accumulation of water by preserving the respiratory properties of the structures. Water ingress is prevented by forming a protective layer around itself internally and externally.
Structures are built to withstand pressure as they are subjected to some plastic deformation forces. There are two load-lifting systems in the buildings: concrete and reinforcements. When buildings with high compressive strength are exposed to flexing, elongation and bending forces, they are deformed with sharp breaks and penetration becomes easier as their integrity is impaired. When the penetration of water into the deteriorated structure is not prevented, the penetrating water may cause corrosion in the reinforcement and deformation in the concrete. Thus, the load that the skeleton can carry begins to decrease. As the bearing capacity of the building decreases, the risk of collapse as a result of seismic movements such as earthquakes increases. In addition, penetrating water can threaten a comfortable living space as it is a carrier and source of nutrition for some fungi and bacteria.
What are Waterproofing Materials?
Waterproofing materials, which have a wide variety, according to their functions; are grouped as surface waterproofing materials and structural waterproofing materials. The materials used in the waterproofing that is made continuously between the surface of the building and the environment where the water is located are surface waterproofing materials. These, in turn, are divided into sliding type waterproofing materials and laying type waterproofing materials.
Sliding type waterproofing materials are prepared by mixing them with suitable mixers. Ready-to-use types are used after thinning with special thinners. It is applied to the surface by applying with a trowel, roller or brush or by spraying.
Structural waterproofing materials are mostly used in the production of concrete in reinforced concrete structures in liquid or powder form to provide ease of manufacture, to obtain better quality concrete and to provide water impermeability. Reducing the water/cement ratio in the reinforced concrete, reducing the capillary gaps in the concrete, clogging the capillary gaps in the concrete.
How are Waterproofing Materials Used?
Waterproofing of wet areas such as balconies, toilets, bathrooms and kitchens is extremely important as they are areas where water is constantly used. Leakage points; Wall joints are weak areas such as joints between cisterns and pipes, and faulty pipe materials that corrode. Where moisture spreads from the floor or walls to the concrete, it can cause extensive damage to the reinforcement embedded in the concrete. For this reason, an impermeable barrier is needed to prevent the spread of moisture on the concrete. Acrylic-based elastomeric waterproofing materials designed to protect wet areas from constantly occurring water leaks can be used for any wet area.
Terraces require a sloping surface to adequately protect the concrete substrate and drain water effectively. It is expected that the waterproofing cover will also protect the parapet walls. Polyurethane liquid membrane waterproofing materials are frequently used in terrace structures and are considered the best waterproofing material. It is highly sustainable in all climatic conditions, including the negative effects of pedestrian traffic and UV rays. It shows high resistance to long-term weather conditions.
The waterproofing materials to be used on the roofs vary according to the structure of the roof. Waterproofing sheet membranes are considered as one of the most important factors in waterproofing the concrete roof, as it keeps the roof system away from the building from water.
Positive side waterproofing in basements takes place on the face of the retaining wall, which is in direct contact with the water source. It becomes the most effective waterproofing solution as it is designed to block the initial water ingress and prevent further leakage. PVC membrane, which is a compact system that protects the building from all sides, acts as a barrier against groundwater. Negative side waterproofing is carried out from the inside of the building, in other words, on the surface of the retaining wall, which has no contact with the water source.
Waterproofing of curtain walls is extremely important in terms of ensuring the safety, comfort and thermal performance of the building occupants as well as the building. Gravity, air pressure differences, capillary action, kinetic energy and surface tension act as a mediator for water entry into buildings. Underground and foundation curtain wall waterproofing should be done at once according to the project details. The basic principle in foundation and underground water applications is drainage insulation systems; drainage provides a dry surface during application as well as minimizing water leaks. However, since the task of drainage is to minimize the water pressure, it is necessary to provide waterproofing on the foundation curtains by using bitumen-based waterproofing materials and bituminous membrane waterproofing covers. If there are bundling membranes coming from the foundation structure, combining them with curtain waterproofing is among the points to be considered. The reason why bitumen-based waterproofing materials are preferred in curtain insulation; The joint is groundless and does not leave a gap between them and the concrete. It is also known that bitumen-based waterproofing materials are extremely resistant to alkalis in the soil. After the waterproofing process is completed, thermal insulation foams and drainage board can also be used as a protective layer to protect the excavation from damage.
In order to prevent leaks that may occur in swimming pools, their maintenance should be done well. Causes such as shrinkage cracks that occur during the concrete curing process, the absence of waterproofing barriers between the pool water and the concrete wall, cracks that occur in the joints over time, malfunctions in the sanitary installations and suction lines, honeycomb formation that weakens the structure during the concreting process can cause leaks.
What are the Types of Waterproofing Materials?
According to the application areas, waterproofing materials; cement based waterproofing material, crystallized waterproofing material, bitumen rubber based waterproofing material, acrylic liquid membrane waterproofing material, bitumen membrane waterproofing, polyurethane-injection waterproofing, epoxy floor coatings, polyurethane liquid membrane waterproofing material, polyurea spray coating as separated.
Advantages of Waterproofing Materials
An effective waterproofing with the use of the right materials; It prevents the corrosion of the reinforcements in the bearing parts of the structures and the decrease in the carrying capacity. In addition, it eliminates the problems that cause the formation of fungus and mold, such as moisture and humidity. In addition to preventing water from roofs and terraces, it also plays an important role in the formation of water leaks in pools or water tanks.
