False: It is not necessary to use waterproofing material elastically on large concrete surfaces as there is no risk of movement and cracking.

True: Elastic material with crack bridging properties should be preferred for waterproofing of large surfaces.

False: It is not necessary to waterproof the buildings where C30 concretes are used

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.

False:Waterproofing is sufficient only for constructions where pressurized water blocking mortars are used.

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.

False: Bituminous membranes can be glued with a welding torch even if there is water accumulation on the surface.

The surfaces must be cleaned, dried and primed prior to application of bituminous membrane with a welding torch.

If my apartment is at the top floor, I only need waterproofing for the section where my apartment is located.

True: Waterproofing is applied the whole of the building terrace, singular point applications will not solve the problem.

False: The lack of waterproofing on the foundation of the buildings has no effect on the demolition of the structure during an earthquake.

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.

False: If the pool is built using solid and reinforced concrete, additional waterproofing is not necessary.

True: Water insulation in the pool can be provided by using elastic waterproofing materials such as bituminous membranes that are properly selected in detail.

False:The use of drainage plate is sufficient for water insulation on the foundation curtain walls.

True: Drainage plate's purpose is to protect the insulation applied on foundation or curtain. It is not a waterproofing material itself.

False: If you want to grow flowers by pouring soil on the terrace, the drainage system applied on the terrace can be enough to solve the problem of water infiltration.

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.

False: Waterproofing is provided if XPS is applied over lean concrete

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.

False: If waterproofing will not provide us energy saving, it is not necessary to apply on the buildings.

True: Waterproofing may not provide energy saving but it will protect against corrosion and ensure that the building to stay strong against earthquakes.

False: If there is good water insulation in water tanks, extra insulation is not necessary in cold joints.

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.

False: Especially if there is heavy rainfall, bituminous membranes can take a little water after a while.

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.

False: Bituminous membranes crack when the weather temperature drops below 0°C

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.

False: Bituminous water insulation membrane is applied as a single coat everywhere.

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.

False: Bituminous water insulation membranes require maintenance every year.

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.

False: Bituminous water insulation membranes are used only on building foundations and roofs.
False: Bituminous water insulation membranes can be applied only on terrace roofs.

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.

False: Bituminous water insulation membranes joints crack in time and takes in water.
False: It is enough to apply waterproofing on our roof where our apartment is located.

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.

False:Waterproofing does not help the structure of the building.
False: Bituminous water insulation applications can be done by any master who knows about it.

True: Bituminous water insulation applications must be done by experts in this field and companies having masters with MEB Certification

False: Bituminous water insulation membranes cannot be applied on steel roofs.
False: Bituminous water insulation membranes are not resistant to chemical materials.

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.

False: It is not necessary to apply any material such as a primer on the surface where the bituminous waterproofing application will be carried out.
False: Bituminous waterproofing membranes have limited usage life

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.

False: Using bituminous waterproofing membranes, can a precise solution be obtained for water insulation?
False:The mineral color of mineral coated bituminous waterproofing covers fade away in 1-2 years and the membrane becomes black.

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.

Yanlış: Bitümlü su yalıtım membranları çok sıcak havalarda erir ve çatıdan damlamalar olur.
False: Bituminous waterproofing membranes melt away in very hot weather and drips from the roofs.
False: One cannot walk over bitumen waterproofing membranes.

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.

False: Bituminous waterproofing membranes can be applied on any surface in any climate without requiring any additional work.
False: The foundation application of bituminous waterproofing membranes is done with 2 coats of 3mm membrane regardless of the foundation depth.

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.

False: Any type of insulation material can be used anywhere in the building like foundations, terrace, roof, wet areas, water depots etc.
False: Cement based crystallized waterproofing material forms a crystal layer up to 100 cm deep in concrete.

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.

False: Water and heat insulation can be done if the weather has no precipitation.
False: Bituminous membrane material can be stocked horizontally on top of each other.

True: Material must be stocked on a smooth ground vertically over the pallet.

False: While applying bituminous waterproofing membrane, material joints can be done by disregarding the marks indicated on the material.
