True: Elastic material with crack bridging properties should be preferred for waterproofing of large surfaces.
True: The water impermeability of the concrete is not directly related to the concrete strength. Water passes through the capillary spaces in the concrete. In practice it is almost impossible to make concrete without gaps. Waterproofing should be applied to all kind of concrete.
True: Pressurized water blocking mortars alone are not enough to insulate water. If it is not applied again, it may lose its strength with time and leakage may occur with water pressure.
The surfaces must be cleaned, dried and primed prior to application of bituminous membrane with a welding torch.
True: Waterproofing is applied the whole of the building terrace, singular point applications will not solve the problem.
True: The iron equipment used in the building foundations which are not waterproofed, is subject to corrosion and rotting over time and the decrease of the building carrying capacity leads to damage during an earthquake.
True: Water insulation in the pool can be provided by using elastic waterproofing materials such as bituminous membranes that are properly selected in detail.
True: Drainage plate's purpose is to protect the insulation applied on foundation or curtain. It is not a waterproofing material itself.
True: A drainage system alone is not sufficient for the creation of greenery on terraces, suitable waterproofing and filtration system must be done too. A system must be developed by using waterproofing materials that are resistant to plant roots.
True: XPS products are used for heat insulation, they do not contribute to the water insulation. Waterproofing must be done additionally by using elastic materials like bitumen membranes.
True: Waterproofing may not provide energy saving but it will protect against corrosion and ensure that the building to stay strong against earthquakes.
True: Pressurized water apply force first on cold joints, that is why it is very important to reinforce these points with insulations bands in terms of insulation integrity.
True: If the bituminous water insulation membranes are applied as described in their technical catalogs and specified by TS11758-2, they will never take water.
True: Bituminous water insulation membranes do not crack in cold weather as they are produced with modified bitumen. They are manufactured resistant to -5°C, -10°C and -20°C depending the usage area. However in practice, they will not crack even in lower temperatures.
True: Bituminous water insulation membranes are used at least in 2 coats on foundations and terrace roofs. If wanted, single coat of 4mm bituminous membranes can be used on pitched roofs with more than 5% pitch.
True: If the bituminous water insulation membranes are applied as described in their technical catalogs and specified by TS11758-2, the will not require maintenance for long years.
True: bituminous water insulation membranes can be used on any kind of pitched roofs as well as terrace roofs as single coat with mineral or 2 coats with aluminum.
True: Waterproofing with bituminous water insulation membranes must be applied the whole of the roof. As water may enter from the places without waterproofing is applied, the whole of the roof must be covered with waterproofing.
True: Bituminous water insulation applications must be done by experts in this field and companies having masters with MEB Certification
True: Bituminous waterproofing membranes exhibit resistance to many chemicals at different temperatures and concentrations. Information on the resistance of bituminous waterproofing membranes to chemical substances can be found in TSEN 13969 Chart A1 and TSEN13707 Chart C1.
True: Bituminous waterproofing membranes selected according to the usage area and adhered according to the technical details continue their performance throughout the life of the building.
True: Since the minerals used in bituminous waterproofing membranes are dried at high temperature after being painted, there is no fading that can be felt in the colors under the sunlight in open weather conditions. However, the effect of environmental pollution and dust on the minerals can affect the originality of the color.
True: It is possible to walk on the mineral bituminous waterproofing membranes and waterproofing covers for the purposes of maintenance, repair, etc. However, the bituminous waterproofing membranes must be protruded with a rubber-based footwear and care should be taken not to damage the bituminous waterproofing membranes during walking. Also, you should not climb over the roofs coated with mineral bituminous waterproofing membranes in very hot weather. If you have to, water the walk area to cool down first and then walk.
True: For the applications with bituminous waterproofing membranes, the material thicknesses and the number of coats should be selected according to the water and floor pressure as given in the following table specified by TS 11758-2 Application standard.
True: The crystal layer created by cement based crystallized waterproofing material cannot be more than several cm. in the concrete poured in Turkish construction areas.
True: Material must be stocked on a smooth ground vertically over the pallet.
