Product introduction

(Prefabricated) non-asphalt-based polymer self-adhesive film waterproofing membrane is a kind of multi-layer composite waterproof material of excellent performance developed by our company and specifically for underground construction place requiring pre-pavement method. It is mainly composed of high-density polyethylene (HDPE) sheet, polymer self-adhesive film and surface particle protective layer with special performance requirements. Before the initial setting of the post-cast concrete, the concrete slowly bonds with the self-adhesive layer of the membrane under the action of gravity. Physical adsorption and crosslinking function during the cement solidification to allow for tight bond between membrane and the post-cast concrete and thus to disable bond failure.

Features

1 Anti-corrosion by seawater: seawater immersion, chloride ion penetration resistance, acid and alkali resistance.

2 Strong chemical stability: common inorganic, organic acids, alkalis, salts and organic solvents are not corrosive to it.

3 Strong deformation resistance: sea ​​reclamation and uneven settlement require high strength and good extensibility of waterproof layer.

4 Fully bonded without water channeling: good elongation at break, when pre-paved and inversely adhered, it forms a skin-type waterproofing structure with the main body structure, which deforms together, and is not affected by the stretching due to the structure and base deformation.

Scope of application

Waterproofing and seepage-proofing of underground projects, such as basements, civil air defense construction, subways, etc.
