Cold-applied Self-adhesive Membrane
Description
Technical Parameters
In enclosed spaces with open flame prohibitions, renovation of old buildings and flammable and explosive sites, cold-applied self-adhesive membrane has become the preferred waterproof material for an increasing number of engineering contractors due to its open-flame-free, direct-bond construction advantages. Our cold-applied self-adhesive membrane takes high-polymer modified bitumen as the self-adhesive core layer, paired with high-strength cross-laminated film or aluminum foil surface layers. Simply peel off the separating film and directly attach it to various base surfaces including concrete, metal and wood for full cold operation with no open flame or dense smoke, drastically elevating construction safety coefficients. The self-adhesive layer of this cold-applied self-adhesive membrane adopts an imported rubber-modified formula with outstanding tack retention and low-temperature bonding performance, maintaining reliable adhesion without debonding or edge curling even at -10℃. Our products have been applied in multiple old community roof renovation and underground internal wall waterproof projects nationwide, earning high client recognition for construction convenience and waterproof performance.
To adapt to diverse scenario demands, our self-adhesive membrane system covers multiple segmented product lines: aluminum foil heat-insulated variants for roofs, cross-film reinforced variants for underground works, and color steel tile special variants for metal roofs. Unlike ordinary self-adhesive membranes prone to summer flowing and winter hardening, we optimize bitumen formulas and adhesive layer ratios to maintain stable physical performance across the temperature range of -20℃ to 90℃. The membrane comes with integrated self-adhesive lap edges-simply align and compact to form a sealed integrated waterproof layer with low construction barriers; ordinary workers can master operation after brief training, helping your clients save substantial labor costs and construction time. For agents, this product features a wide range of applicable scenarios, low construction difficulty and minimal after-sales issues, with strong market acceptance whether targeting engineering clients or retail channels.

The factory features an independent R&D laboratory continuously iterating and optimizing self-adhesive layer formulas, launching multiple targeted products including low-temperature resistant, high-temperature resistant and high-elongation variants. We maintain long-term cooperation with Fortune Global 500 construction enterprises including China State Construction and China Railway Group, with products widely applied in residential, municipal and transportation engineering works of all types. By partnering with us as a supplier, you gain access to stable production capacity, reliable quality and full-chain technical support spanning product selection to construction guidance to effortlessly address demands of various complex projects.
Packaging & Transportation
We design exclusive export packaging tailored to the characteristics of cold-applied self-adhesive membrane. Every roll is individually wrapped in PE film, fitted with hard paper tube cores and corner guards, then palletized as a whole and wrapped with stretch film to prevent extrusion deformation, adhesive layer adhesion and separating film damage during long-distance transportation. Packaging forms can be flexibly adjusted per client demand, including palletized packing, loose packing and carton packing, with shipping marks fully customized to client requirements. Multiple trade terms including EXW, FOB and DDP are supported, and we maintain long-term cooperation with multiple professional international freight forwarders to deliver competitive logistics quotations. Photos and videos are taken throughout container loading for full visibility of cargo status, eliminating concerns over transportation risks.
Frequently Asked Questions
Q: Can this self-adhesive membrane be directly laid on damp concrete base surfaces?
A: The construction base must be free of standing water, floating dust and sharp protrusions; slight dampness of the base will not impact bonding effects, but ponding must be thoroughly cleared.
Q: Can construction proceed under low-temperature environments without adhesion failure?
A: Our standard variant supports normal construction above -5℃, while the special low-temperature variant adapts to construction environments of -10℃, enabling smooth progress of winter projects.
Q: Do lap joints require extra treatment?
A: The membrane comes with integrated self-adhesive lap edges; simply align and compact. Special sealing compound is recommended for reinforcement at critical joint nodes.
Q: What is the minimum order quantity?
A: Standard variants have an MOQ of 100㎡, special customized variants 500㎡, with mixed loading of different models permitted as long as total order volume meets requirements.
