The roofing membrane waterproofing construction technology refers to a method of using membrane waterproofing material for construction in the roof part of the building. This method has the advantages of fast construction speed and simple construction, and can also achieve a relatively good waterproof effect at the same time. However, in order to do a good job in the roofing membrane waterproofing project, in addition to being proficient in the specific construction process, you also need to pay attention to some details.
The waterproofing construction process of the roofing membrane first needs to be cut and cut, that is, the membrane is cut and arranged according to the design requirements. Then the base layer needs to be treated, and the base layer should be flat, dry, free of loose, hard bumps, etc. If gluing is required, the gluing surface should be glued flat. Then there is the gluing construction, brush the primer on the base layer, lay the coil on the primer, and press the coil with a scraper to make it fully bonded with the underlying substrate. In the gluing process, the thickness and uniformity of the gluing should be controlled to ensure that the bond between the coil and the base layer is firm.
Next is the welding construction. After the coil is laid, the so-called "aging" of the indentation is required, that is, the indentation of the coil is cut, tapped, etc., to make it sufficiently soft and easy to weld. Then, high-temperature hot air is applied to the weld to melt the coil and achieve a firm connection at the weld. In the welding process, it is necessary to master the temperature and welding speed to ensure that the welding effect is excellent and there is no water leakage.
Finally, there is inspection and acceptance. After the completion of the above projects, it is necessary to test and accept the waterproof effect. Stroke with defects in the coil is reprocessed until the design requirements and standards are met.
The matters that need to be paid attention to in the waterproofing construction of roofing membrane are:
The waterproofing construction of the roofing membrane must be carried out outdoors under the conditions of sunny days, no wind and no rain to avoid affecting the construction quality.
The bond between the coil and the base and adjacent coils must be firm, the gluing construction should be uniform, and the temperature and speed during welding should be well mastered to avoid the phenomenon of coil detachment and water leakage.
During the construction process, it should be carried out in strict accordance with the design requirements and construction specifications, and avoid changing the design at will, so as not to affect the waterproof effect of the roof.
When the anti-corrosion coating is plated on the roof, it should be carried out in accordance with the design and standards to avoid defects and false suspension of the coating, so as not to affect the waterproof effect of the entire roof.
To sum up, the waterproofing construction process of roofing membrane needs to be carried out in strict accordance with the design requirements and construction specifications, and at the same time pay attention to the details in the construction to achieve excellent waterproof effect and ensure the overall quality and service life of the building.
