Click the blue word above to pay attention to our Jingshi waterproof roof waterproof project, which is an important project of housing construction
.
When the thickness of the coiled material is less than 3mm or the covering material is aluminum film, the hot-melt construction method should not be used; The hot mastic pasting method is a traditional construction method, which is mainly used for the laminated paving of three felts and four oils or two felts and three oils of petroleum asphalt felt; Hot air welding is to heat the lap joint of waterproof coiled material with hot air welding gun and bond it
.
The quality of the project affects the life of buildings and residents, of which waterproof material is a key issue
.
It is mainly used for the laminated paving of three felts and four oils of petroleum asphalt felt or two felts and three oils; The self-adhesive method is to directly bond the waterproof coiled material with self-adhesive without brushing adhesive materials
.
At the same time, before paving a large area of waterproof coiled material, node sealing treatment, treatment of additional layer and roof drainage concentrated parts, and empty paving treatment of separation joints shall be done first（ 2) The lap joint of waterproof coiled material must be tight, the joint opening shall be overlapped along the water flow direction, and its width shall not be less than 50mm
.
After the waterproof engineering construction is completed, the next process can be carried out only after passing the water storage test（ 4) When the hot-melt method is used for construction, the construction can be carried out at the temperature of – 10 ℃ when the material allows, which is not limited by the season, and the construction shall not be carried out in rainy days and grade 5 wind days
.
It is mainly used for lap seam welding of thermoplastic synthetic polymer waterproof coiled material
.
What kind of roof waterproof coiled material do you have? What are the construction methods? What are the precautions? Then turn it down quickly Jingshi waterproof ···········································································································
.
If there are flammable equipment on the roof, the construction must be careful and pay attention to safety to avoid fire

Compared with the waterproof plate, although the structural principles of the two are similar, the waterproof roll is lighter and softer
.
It is mainly applicable to synthetic polymer waterproof coiled material with self-adhesive and high polymer modified asphalt waterproof coiled material
.
Asphalt waterproof coiled material is made of base paper, fiber fabric, fiber felt and other matrix materials impregnated with asphalt, and powder, granular or flake as covering material; High polymer modified asphalt coiled material is made of synthetic high polymer modified asphalt as coating layer, fiber felt, fiber fabric or plastic film as matrix material, and powder, granular, flake or plastic film as covering material; Synthetic polymer waterproof coiled material is based on synthetic rubber, synthetic resin or their blends, added with an appropriate amount of chemical additives and fillers, and processed by mixing, calendering or extrusion
.
Cold construction process does not need heating during construction
.
It is mainly suitable for synthetic polymer coiled material and high polymer modified asphalt waterproof coiled material; Cold mastic pasting method is to directly apply and scrape the cold asphalt cementitious material prepared in the factory and paste the asphalt felt

Jingshi waterproof ······························································································（ 1) The waterproof coiled material shall be paved parallel to the roof ridge from bottom to top, and the construction sequence of “first high then low, first far then near” shall be adopted for strict construction
.
It is generally divided into cold bonding method, cold mastic bonding method and self-adhesive method
.
At the same time, the hot-melt method construction is easy to catch fire, and there shall be no other open fire operation on the construction site
.
Hot construction process is generally divided into hot melting method, hot mastic bonding method and hot air welding

.
Moreover, the curled form is easier to install flexibly and convenient for transportation
.
The joints of upper and lower houses shall be staggered by 250mm from left to right, and the division of construction section should be set at roof ridge, gutter, deformation joint, etc（ 3) The waterproof material coiled material layer shall be firmly bonded without defects such as hollowing, damage, sliding, edge warping, blistering and folding
.
It is mainly used for lap joint welding of thermoplastic synthetic polymer waterproof coiled material
.
The waterproof roll mainly includes asphalt waterproof roll High polymer modified asphalt coiled material and synthetic polymer waterproof coiled material
The pressure burying method is mainly used for empty paving method and inverted house
.
During construction, most of the coiled materials are not bonded with the base course, and pebbles are used for pressure burying above, and the lap joint and surrounding are fully bonded; Mechanical nailing method is mostly used for laying polymer modified asphalt coiled material on wood base, usually using galvanized steel or copper nails to fix the coiled material waterproof layer
.
Cold bonding method is to bond the coiled material with the base layer and the coiled material with the coiled material by using the adhesive
.
It can be laid on the contact surface of any shape, and has a certain cushioning effect on the ground
.

.
The hot-melt method is to melt and paste the hot-melt adhesive at the bottom of the hot-melt waterproof coiled material with a flame heater
.
Mechanical fixation process is generally divided into burying method and mechanical nailing method
.
The most commonly used waterproof material is waterproof coiled material, which accounts for 80% of the whole building waterproof material
.
