Product overview


Dayu®Self-adhesive polymer modified asphalt waterproofing membrane (tire) is a self-adhesive waterproofing membrane composed of tire base, self-adhesive modified asphalt gum and surface material.


l fetal baseHigh quality filament polyester felt.

l GlialSBS modifier is used to modify petroleum asphalt to improve its high and low temperature resistance, fatigue resistance and bonding performance, and to improve the self-adhesive performance of modified asphalt by adding tackifying resin and other additives.

l Surface material: Polyethylene film, silicon-coated isolation film.




Product Features


High tensile strength, strong tear resistance and excellent mechanical properties.

The glue has strong adhesive ability, self-healing function, and excellent water tightness of the nail rod.

Low temperature flexibility, good durability, long-term protection of waterproof ability.

Cold construction (no fire), self-paste, construction efficient, safe and environmentally friendly.

It can form a composite waterproof layer with other compatible coatings or coils to meet higher grade waterproof requirements.

Scope of application


Applicable to all kinds of industrial and civil buildings underground, roofing and other non-exposed parts of the waterproof project.

Especially suitable for non-fire operations and other projects of waterproof engineering.



Construction process


Basic requirements: solid, dry, no sediment, laitance, no empty drum, loose, sand and other phenomena.

Interface treatment: uniform spray (roll) coating matching base treatment agent, improve the coil and the adhesion of the base.

Trial laying of coiled material: lay the coiled material flat on the base surface, align the elastic line or the overlapping edge of adjacent coiled material, adjust the overlapping width, and rewind after standing for a period of time to release the stress.

Cold adhesive paving: push forward to roll the paving coil, tear off the isolation bottom film, compact and exhaust to make the coil and the base closely bond.

Body lapping: tear off the independent lapping film and roll the lapping edge to make the asphalt adhesive layer body bond tightly.




performance index


Products in accordance with the national standard "self-adhesive polymer modified asphalt waterproofing membrane" GB23441-2009 manufacturing.

The performance index meets the requirements of PY coil in the standard.
