High molecular weight (Non-asphalt base2) Self-adhesive film waterproofing membrane

Product introduction:

Non-asphalt based polymer self-adhesive membrane waterproofing membrane,It is the company that adopts innovative processes.,to macromolecule（HDPE、TPO、EVA、ECB）A sheet made of resin as the main body,Direct coating of non-asphalt-based polymer hot melt adhesive and sand release layer on the surface of extruded sheet（or isolation membrane）One-time extrusion molding of polymer self-adhesive waterproofing membrane,The coil has pre-laid anti-adhesion performance,Can be integrated with the concrete structure self waterproof.

Polymer self-adhesive film and post-pouring concrete（or binder）Cement slurry without initial setting under pressure,Permeation through the release layer by creep phase,Formation of effective interpenetrating bonds and large intermolecular forces,The coil self-adhesive layer reacts with the liquid concrete slurry after consolidation.,Form waterproof and concrete structure without gap,Eliminate the hidden danger of water channeling between layers,Can effectively improve the reliability of the waterproof system.

(1)Bottom Plane Construction

Clean up the base→base surface elastic line→The details are as shown in（Flat facade junction,deformation joint,Additional reinforcement such as canal root) →Large-area laying of pre-laid anti-adhesive waterproofing membrane→Coil Lap Treatment→node construction→Self-test→Acceptance→Isolation film of uncovering coil without grit→Binding reinforcement→Pour concrete.

（2）Vertical surface construction

Install facade support→Check,Cleaning the base surface of the elevation→Coil positioning spring line→The details are as shown in（Flat facade junction,deformation joint,Additional reinforcement such as canal root) →Laying of pre-laid anti-adhesive waterproofing membrane→Mechanical fixation of coil→Coil Lap Treatment→node construction→Self-test→Acceptance→Uncovering coil isolation film without grit→Binding reinforcement→Pour concrete.

（3）tunnel vault

tunnel vault→bullet line→Mounting support（Gasket or dowel) →Laying of pre-laid anti-adhesive coil→Mechanical fixation of waterproofing membrane（WELDING OR LIFTING) →Overlapping treatment→Node Processing→Uncover the isolation membrane of waterproof coiled material→Binding reinforcement→Pouring concrete.

Polymer self-adhesive film waterproofing membrane is mainly used in the basement,Pipe gallery,Subway,Tunnel,Waterproofing of municipal buildings, etc.,anti-seepage works.
