Product Details

Non-asphalt-based polymer self-adhesive film waterproofing membrane is the company adopts innovative technology, mainly made of macromolecule (HDPE, TPO, EVA, ECB) resin sheet, directly coated on the surface of extruded sheet Non-pitch polymer macromolecule hot-melt adhesive and sand anti-adhesive layer (or release film) is a polymer self-adhesive waterproofing membrane that is extruded at one time. The coil material has pre-shopped anti-sticking properties and can be integrated with self-waterproofing of concrete structures.

Non-primary cement slurries in polymer self-adhesive films and post-cast concrete (or binders) penetrate through the creep phase through the anti-sticking layer under pressure to form effective interpenetrating bonds and large molecules. Force, the self-adhesive layer of the coil reacts with the liquid concrete slurry to form a gap-free combination between the waterproof and the concrete structure, eliminate hidden troubles between the layers, and effectively improve the reliability of the waterproof system.


Construction process:


(1) Bottom surface construction

    Clear the base layer → base surface elastic line → detail processing such as (additional reinforcement of flat facade intersection, deformation joint, pipe root, etc.) → large-area prepaid anti-sticking waterproof membrane material → coil overlap processing → node construction → self Inspection → Acceptance → Isolation film with unrolled unrolled material → Bundle reinforcement → Cast concrete

(2) Vertical surface construction:

    Install the facade support → check, clear the base surface of the façade → locate the elastic line of the coil material → detail processing such as (additional reinforcement of flat facades, deformation joints, pipe roots, etc.) → Laying the pre-paste anti-sticking waterproof membrane → do Membrane mechanical fixing → Coiled material processing → Node construction → Self-checking → Acceptance → Unrolling material barrier film without sand grain → Tied bar → Cast concrete

(3) Tunnel vault

    Tunnel vaults → Lines → Installation support (gaskets or hangers) → Laying of pre-paved anti-sticking membranes → Waterproof membranes Mechanical fixing (welding or hanging) → Lapping processing → Nodal handling → Detachable waterproofing membranes → Tied bar → Cast concrete.
