Bitumen is used for insulation in the building, and sacks are used to stabilize the bitumen. The sack fibers reinforce the bitumen and stabilize the bitumen in place. Qirguni is executed in two modes.
as one layer: First a layer of bitumen and then a layer of sacking and again a layer of bitumen is poured on top of it again. In two layers: First a layer of bitumen and then a layer of sacking and again another layer of bitumen and then a layer of sacking and finally another layer of bitumen. Important note: The thickness of the bitumen sack is about 2 to 3 cm. Lime and slag cause the bitumen to rot, and it should not be placed or used in the vicinity of this mortar, and sand and cement mortar is more suitable for this purpose. It is an old but always effective method for insulation, which is suitable for the insulation of sanitary facilities due to its high thickness. Definition of Qirguni It is a type of isolation and insulation that uses bitumen and gunny sack (Chattai) as the main materials for insulation. Now many companies are installing bitumen. Izogam Sayvand is a reliable company in the field of waterproofing, which is at your service with years of experience in Izogam and bitumen insulation services. Other applications of Qirguni Bitumen sack is used to insulate bathrooms and kitchens, the base of metal columns to prevent them from rusting, it is used on wall chairs and other things. What is the useful life of Qirguni
?How is Qirguni performed? In general, after the implementation of the facilities that pass through the floors and roof, and the tilting and rounding of the roof, the isolation stage of the building begins. For execution, the working surfaces must be completely dry and smooth, for this reason, the execution of the work must not be done when it is raining. In order to sand the roof, the slope of the roof must be done correctly first, and then the desired surface must be completely dry. The number of gravel layers according to the type of protective coating on it, as well as weather conditions and other factors. . After the completion of the isolation, the test stage is carried out by dewatering the surface of Qirguni for 24 hours, during which no leakage should be seen. For implementation and installation, experts and experienced people should be used in the work. Expert and experienced people in Izogam Sayvand Company are ready to provide services for all construction projects to you dear ones.
Important points in doing Qirguni 1- You must cover the surface completely with cement before performing the sanding so that the cement does not have cracks and the insulation is completely attached to the surface and all the seams are covered. 2- In the next step, bitumen is poured on the cement with a maximum temperature of 180 degrees so that all the cemented parts are covered so that water and moisture do not penetrate it and enter the building. 3- Then cover the bitumen surface with a grade 1 sack and pay attention to the fact that the sack does not get torn during expansion. 4- At this stage, by combining soft bitumen with hard bitumen, we cover another layer of bitumen on the sack, pay attention so that the sack does not tear in this part, and the bitumen is spread over the entire surface and no part is left empty. Up to this part, the roof is almost completely insulated. 5- In the fifth step, to close the way of water infiltration, we do the grouting in reverse, be careful that if you use grouting to insulate the building, the bearing capacity of the building must be checked to see if the building can withstand this weight or not. ? 6- In the last step, we cover the sack again with a layer of bitumen, note that all the tips we had for the previous steps must be observed in this step as well, so that the bitumen is installed in the most correct way possible. 7- At the last stage, Qirguni should be tested to see if it is able to prevent water penetration or if water penetrates through it. In order to test the bitumen, it is necessary to drain the water one day later, and if the water penetrates through the insulation, you should cover the place of water penetration again with a layer of bitumen.
