Polypropylene waterproof coil is the key material of single-layer roofing system. The waterproof film replaces the 1.5 mm thick polypropylene waterproof film. Its corrosion resistant coating improves the aging resistance of the product and extends the service life. The following Dibao waterproof manufacturers to give you a detailed introduction, let's understand together.

According to the wind speed calculation to determine the number of each individual engineering fixed parts, spacing, distribution area, etc.

When the polypropylene waterproof coil is embedded, the deformation joint of the polypropylene waterproof coil should have sufficient expansion margin to replace the damage of the roof to the film. The displacement should be smooth and not affect the appearance.

The PE film at the corner should be sealed with butyl tape, which should be inserted into the steel exterior wall. The waterproof film here is completely adhered to the outer wall, fixed with a closed pressure rod and sealed with sealant.

The polypropylene waterproof roll is inserted into the steel plate, then it is fully adhered to the steel plate with an adhesive, secured with a sealing bead, and then sealed with a sealant.

When installing and winding the lighting tape, care should be taken not to damage the lighting board, and replace it in time when cracks appear. The water resistance of the fixing screws is especially important. Multiple waterproof features are required, such as waterproof washers and titanium bands.

The design and construction requirements of single-layer spiral roof are high, and the factors affecting the quality of roof engineering are different. Polypropylene waterproof coil will directly affect the replacement of the roof and waterproof effect.
