产品描述

 


 

product description

 

The high-quality long-fiber polyester felt is used as the base, and the SBS thermoplastic elastomer (styrene-butadiene-styrene) is used as a modifier to modify the petroleum asphalt, and the imported root-blocking agent is added to prepare the rubber layer. The coating material is an elastomer modified asphalt waterproofing membrane made of fine sand, mineral pellets or polyethylene film.

 


 

Features

 

The SBS coils are all made of long-fiber polyester felt base. Compared with the shorter-fiber polyester felt, it has more stable tensile strength, greater elongation and better dimensional stability, and the product quality is more reliable.

 

Excellent resistance to root penetration.

 

Hot melt construction, convenient construction and wide application.

Scope of application

 

It is suitable for building projects with planting roofs, planting roofs, landscape lakes and other greening requirements.

 


 

Construction process

 

Grassroots requirements

 

 

The base layer is dry and solid, free of sediment, garbage, no empty drums, loose, sanding.

 

Coating treatment agent

 

Spray or roll the matching base treatment agent to the base layer to ensure that the base treatment agent is uniform and full of the base layer.

 

Trial roll

 

The coil material is spread out on the base surface, and the elastic wire or the overlapping edge of the adjacent coil material is aligned to ensure the overlapping width, and the stress is released after being released.

 

Hot melt paving

 

The flame is baked on the lower surface and the base surface of the coil, and the gel melts and rolls the coil in time, and is compacted and exhausted, so that the coil and the base surface are closely adhered.

 

Lap processing

 

At the same time of hot-melt laying, press the lap joint with a pressure roller to extrude 5~8mm molten asphalt (considered as reliable lap joint).
