Water insulation of buildings, which is traditionally the last forty years, with asphalt and bitumen sack was carried out with the advent of insulation and moisture and advantages of this type of insulation gradually gave way to the insulation . Today, most of the buildings in the P And Foundation And What the door isolation Walls, Services And Back Roofing, Waterproofing insulation layer is done .

What and use

Waterproofing coating of bitumen and synthetic fibers that attach the roof to heat the substrate and the influence of water and moisture to prevent the environment. Lifetime of insulation on average 10 A year .

Fusing a phenomenon the industry and relies on the knowledge, experience, (experience) and technology in order to secure structures against moisture from rain and snow before. Fusing the various species is, after passing through various tests in laboratories, processing plants, will increase its stability. The test is given as the national standard Aizier 3-3885 .

Layer-forming materials

Multiple layers in order from the bottom as follows: :

Layer Polyethylene (polyethylene film) Or mineral powder (mineral powder) Or aluminum foil (aluminum foil)

Texture (tissue)

Polyester (polyester)

Special additives

Layer Polyethylene (polyethylene film)


Fusing lightness and high resistance due to the following alone is a perfect moisture barrier :





Water tanks


Irrigation channels






Parking class


Pipes for water, gas, oil

Livestock etc. …

Isogam production process by the machine-made production line

Depending on the type of product (single layer or double layer) tissue and polyester are bitumen into pan. Then, roll and pitch is impregnated. Also, the thickness of the layer is adjusted by the outlet embedded on top of the tarpaulins . The aluminum sheet layer impregnated with material, attached to the dock and into the water. The layer is cooled down through the water duct and crossed between the rollers . The next step is to add back the layers and layers of plastic materials are elevator storage. The lift makes temporary storage insulation layer on the device, and stop production. Fans also drying, drying materials are doing. At the end of the insulation into a roll now and during 10 Km around the cone-shaped rod, roll (the ball) is. After the roll, the film is cut by the throw to throw out .

Types of rubble

The main constituent materials can be divided into two types :

1 . Polymeric materials using pure bitumen 70-60: element Main the door This Kind of Waterproofing Bitumen Pure 70 – 60 Been And Has Quality Very Upper the door Comparison With Waterproofing Blown Is. Bitumen Pure 70 – 60 From Refinement Oil Raw To Hand Attend. As a result of heating oil, gasoline, petroleum solvents, kerosene, gas oil and other light oils in refinery distillation towers isolated and in the heat of about 380 degrees (at normal pressure), pitch it to stay that The face is solid or semi solid . Pure bitumen, have been named by the degree of their influence. Bitumen 60/70 in sealing materials consumed .

Materials to make polymeric rubbers : pure bitumen 70-60, polyester, tissue layer of aluminum 14 To 16 Micron, Plastics, Insulating bitumen, Talc powder, Materials APP Degree 1 And 2 , plastic sack tufts

To produce such pure bitumen rubble 70 – 60 And other raw materials listed in Table A is a polymer enters the mixer. Mix the cooked ingredients listed on the mixer. Mixer output, is a liquid called polymer materials. Polymer materials in the production line has become the waterproofing layer .

2 . Fusing blown using fuel oil (mazut): The main element in this type of insulation is blown bitumen and polymer materials of lower quality and less life is .

Blown bitumen: bitumen blowing hot air blown from the oil obtained. In this process, hot air with a temperature 200 until the 300 ° C by leaky pipes containing fuel is blown into the chamber. The result of this process, the hydrogen atoms in the molecules of hydrocarbons with oxygen in the air and water formation, operation polymerization occurs. Blubber bitumen has a lower degree of penetration than pure bitumen, it has a higher degree of smoothness and a lower sensitivity to temperature variations . This type of pitch to make more sheets cover the roof, car batteries and Coating is used. Symbol bit blown R Is. For example, bitumen 80/25 R Means blown bitumen with a degree of softness 80 And degree of infiltration 25 Is .

Materials needed to make blown bitumen : blown bitumen, polyester, thai, aluminum layer 14 To 16 Micron, Plastics behind the layer of rubble, Talc powder

To produce this type of fuel oil into distillation tower and postoperative Ayzgam polymerization, into the blown bitumen. It should be noted that an increase blown bitumen produced no material need not be facing directly into the production line .
