What is HDPE waterproofing membrane(Non-asphalt-based,self-adhesive)?

HDPE waterproofing membrane(Non-asphalt-based,self-adhesive) is the company adopts innovative technology, mainly made of HDPE 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.

What are the basic features of HDPE waterproofing membrane(Non-asphalt-based,self-adhesive)?

▪ Combining the advantages of polymer waterproofing membrane and self-adhesive membrane, it greatly improves the performance of puncture resistance, self-healing, high and low temperature resistance, and more stable chemical properties;

▪ Adopting self-adhesive construction technology makes construction more convenient;

▪ The self-adhesive layer adopts the environmentally friendly polymer self-adhesive developed by our company, which greatly improves the aging resistance performance;

▪ The possibility of preventing water leakage in polymer coil materials has been achieved;

▪ Safe and environmentally friendly, both polymer substrates and self-adhesive materials use environmentally friendly formulas.

What is HDPE waterproofing membrane (Non-asphalt-based,self-adhesive)used for?

HDPE waterproofing membrane is mainly used in waterproofing and seepage prevention projects in basements, pipe galleries, subways, tunnels, and municipal buildings.

Technical Data Sheet

HDPE waterproofing membrane(Non-asphalt-based,self-adhesive) meets the GB/T 23457-2017 standard, with its main physical and mechanical properties

Construction technology

(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.
