Hdpe impermeable geomembrane hot-melt gasket

EVA waterproof board hot-melt gasket, special waterproof material for subway, and hanging tunnel waterproof board are used to achieve hanging hanging without through nails, which is completed in one time. It can greatly simplify the construction difficulty of traditional waterproof materials in tunnels, improve the laying efficiency, shorten the construction period, and significantly reduce the comprehensive cost of the project.

EVA waterproof board hot-melt gasket is generally divided into two types:

1. Separated EVA waterproof board: the geotextile and waterproof board are laid in layers, and the waterproof board and geotextile are connected with the tunnel anchor bolt with hot-melt gasket.

2. Composite EVA waterproof board:

A: Geotextile and EVA waterproof board are integrated;

B: Point composite of geotextile and EVA waterproof board;

C: Geotextile and EVA waterproof batten composite.

Splicing welds are reserved at the edge of the product, and the geotextile is equipped with lifting straps, which are laid on the site as a whole and completed at one time. The content of elongated and flat particles in gravel particles shall not exceed 20%.
