The waterproofing membrane is a very resistant layer whose main base is bitumen and together with other synthetic fibers forms insulation to prevent water and moisture from entering.
As mentioned, waterproofing is made based on the use of bitumen, petroleum materials and some mineral materials, which can be used in the foundations of structures, insulating surfaces to prevent moisture and water penetration, such as the walls of swimming pools and rooftops, etc.,
And we can also mention the insulation of seams, gaps and other places intended for insulation, which is one of the advantages of this type of waterproofing, despite the variety of layers and materials used in its production, is the ease and speed of its installation.
The materials used in waterproofing layers can be industrial bitumen 60-70 or natural bitumen, APP polymer materials, tissue, woven and plain polyester and mineral materials (talc powder, carbonate, etc.), aluminum and nylon foils from poly Ethylene is used.
In waterproofing, bitumen (a mixture of bitumen and improving additives) is used as an impregnating agent for each layer, and mineral powders such as talc are used in high levels so as not to stick inside the packed roll. Plastic film is also used on the surface with the product’s logo and promotional items. It is worth mentioning that in a number of products, the top surface is covered with aluminum foil.
Method of production:
The tissue and polyester materials are entered into the bitumen tank, which was prepared in the baking ovens before this stage, in the desired type and quality, and then it is mixed with the primer or blown bitumen materials and in the last step of this part, the thickness of the waterproofing is adjusted by setting the desired standard.
In the new stage, the aluminum foil sheets are attached to the layer combined with the material, and in order to reduce the temperature, it enters the cold-water pool so that the plastic layer can be added to it. After cooling in the pond, waterproofing is stuck together in several layers and passes through the cold rollings, and in the continuation of the process, polyethylene film is added to the lower part of the layers.
After this step, they enter the storage elevator to be completely dried by waterproofing drying fans, and finally it is directed to the rolling machine to be packed around a cone-shaped rod as a product roll, and at the end of the operation, the produced product will be cut and rolled into ten meter long rolls and thrown out by the pulling system.
