Ⅰ. Product Introduction
The hanging waterproof board for tunnels is a new type of waterproof material for tunnels developed by our company. It can realize the one-time completion of line hanging construction that a nail can pierce through without drilling a hole, which greatly simplifies the construction difficulty of traditional waterproofing materials in tunnels, improves the quality of laying and Laying efficiency, shortens the construction cycle, greatly reduces the comprehensive cost of project, and has a strong market competitive advantage.
Ⅱ. Product Series
Separate waterproof board: geotextiles and waterproof board are laid in layers.
Composite waterproof board: geotextiles and geomembrane are combined as a whole, and in a way of point-type and strip-type. The edge of products has splicing welds. And geotextiles is equipped with sling, can be laid on the site as a whole and completed in one time.
Ⅲ. Product Specifications
Polyester needled geotextiles : 300-400g/m2.
PE/EVA/ECB/ECD synthetic resin rolls thickness: 0.8, 1.0, 1.2, 1.5, 2.0 mm.
Product width: 2-4m.
Product length: According to customer requirements.
Ⅳ.Technical Performance
Meeting the technical indicators specified in the GB/T18173.1-2012 standard.
Ⅴ.Use Range
Railway tunnels, road tunnels, subways, industrial and mining, and various municipal underground projects.
