Roof waterproofing is a very important part of home renovation. Its good or bad will directly affect our future use and living security. If the waterproofing of the roof is not done well, then it can be said that the trouble is endless. Therefore, the following Xiaobian introduces the waterproof material selection of roofing and the characteristics of roofing waterproof material.
Roof waterproof material selection
1, regional, the environment in which the building is located
The amount of rainfall is a factor that must be taken into account. Rainy in the south and less rain in the north, the requirements for water resistance of materials in different places are different. Different temperature environments require different material heat resistance and low temperature properties.
2, the actual needs of building roofs
The actual condition of the roof is different from that of the waterproof material. Whether the person is on the roof or whether the waterproof layer is on the top is a factor affecting the selection of the waterproof material. People on the roof should take into account the effect of stamping on the waterproof layer of the roof and whether it will damage the waterproof layer. The installation of my equipment to the waterproof layer damage, repair and other issues are to be considered.
3, project requirements
Engineering grade, waterproof grade requirements, reaching a few levels of different waterproof grades for waterproof materials, waterproof technology is also very different. Different water levels correspond to different years, and the useful life of waterproof materials is an indicator of material selection.
Roof waterproof material characteristics
1, has a good weather resistance, light, heat, ozone, etc. should have a certain capacity.
2, with water resistance and acid and alkali resistance.
3, the external temperature and external forces have a certain degree of adaptability, that is, the material's tensile strength should be high to withstand the temperature changes and deformation caused by various external forces and grassroots expansion, cracking.
4, good integrity, can not only maintain its own bond, but also with the base layer firmly bonded higher peel strength, the formation of a stable impermeable overall.
What are the waterproof materials for roof?
1. CH-108ZYY polymer cement waterproof coating
CH-108ZYY polymer cement (also called elastic cement) is a two-component waterproof coating material based on acrylate synthetic polymer emulsion, adding special cement, inorganic curing agent and various additives. It has Good film forming, impermeability, adhesion (strong bonding with concrete, brick, stone, tile, ZYY plastic, color steel sheet roof, airport roof, wood, glass, etc.), water resistance, and Weatherability, in particular, can be cured and filmed on a wet base. ZYY composite waterproof coating is divided into ZYY-1 type ZYY-2? Two types, ZYY-1 type is mainly used for waterproofing of large deformation of architectural parts, such as roof, wall, bridge and other parts.
2, HG203 waterproof seal coating
HG203 waterproof seal coating introduces the most advanced high-tech technology in the United States and is made of imported raw materials. It is a real environmentally-friendly one-component water-curing polyurethane waterproof seal coating. The new waterproof sealing coating has passed the appraisal of scientific and technological achievements of the Guangdong Provincial Construction Committee and won the Guangdong Provincial Key New Product Certification.
3, YYA special waterproof anti-seepage slurry
YYA special waterproof anti-seepage slurry is a new impervious waterproof material. It is a gray powder composed of dozens of pure inorganic components. It is non-toxic, odorless, flame-retardant and environmentally friendly. It can be used in food and drinking water projects. After the addition of water, a series of redox reactions occur. After hardening, it has high strength (7 days over C35), water impermeability, high temperature resistance (400°C), UV resistance, frost resistance (-50°C), anti-aging, no shrinkage, oil stain resistance. With strong adhesion, it can carry water on the back surface, and the thickness can be arbitrarily adjusted (0.5--200mm) according to need. It has excellent backwater surface waterproof, impermeability and moisture resistance, and it has secondary repairing function, especially good at governance. Difficulties in the leakage of concrete masonry structures have been tested by the China National Building Material Testing Center. They have been listed as one of China's major construction and application products for waterproofing and one of the top ten brands of waterproof materials. It is the best choice for durability.
Editor's summary: The selection of waterproof materials for roofing and the characteristics of waterproof materials for roofing are introduced here. I hope to help everyone. If you want to know more about yourself, you can follow the information on this site.

The Installation of Mounting Unit
1. Make the concrete base according to solution drawing, locate embedded bolts and set out strings by Laser Level to ensure the centers of embedded bolts in the same elevation as accurate as possible on vertical, horizontal direction and at end face.
2. Locate the Anchor Plate on the concrete base and adjust the position according to solution drawing(remove M14 washer,M14 spring washer,and M14 nut if they are connected to embedded bolts now),and then fasten M14 washer, M14 spring washer, and M14 nut with the tightening torque of 60N.m.
3.Take out the Hexagon Bolt Kit with Post B Corrugated Gasket M12x95 and remove its nut, spring washer, one washer, and corrugated gasket. Insert the Post A, B, C in to Anchor Plate according to the Hexagon Bolt Kit with Corrugated Gasket M12x95 drawing and then fix them by two sets of Hexagon Bolt Kit with Corrugated Gasket M12*95. Post C Post A
4.Remove the bolt kits M12*90 from all the Posts and Pre-Assembled Supports and unfold the embedded Supports, fasten them on the Posts by bolt kits M12*90 according to the drawing.
Installation of Rails
1.Please check the length of Beam before place it onto the Pre-Assembled Supports, otherwise extend it with Splice forBeam first. There are 4 self-tapping screws in each side and total 8 self- tapping screws in both sides. We strongly recommend NOT extend the Beams on Preassembled Supports.
2.Before locate the Beams, mark the position of the Beam son the surface of Pre-Assembled Supports with maker pens according to solution drawing for easier installation. Place the Beams on the 55*80 Tube of Pre-Assembled Supports and fix it with C Clamp Kits. Install all the Beams in the same step. The tightening torque will be 20N.m. C Clamp Kit Side Beam(Please arrange 3-4 persons to install when the array is long.)
Installation of Solar Panels
1.Place the panels above the Beam 85, fixing it with Wide End Clamp Kit in the side and Inter Clamp Kit in the middle. Install all the panels in the same steps until complete installation of al panels. Fasten all the bolts with tightening torque of 10N.m.
2.Complete installation, and please inspect and make sure all the bolts are fastened.
