Asphalt Self Adhesive Waterproofing Membrane Without Substrate 1.5mm 2.0mm

Self-adhesive Polymer Modified Asphalt Waterproofing Membrane Without Substrate

Product Introduction

Fiberless self-adhesive polymer modified asphalt waterproofing membrane ( N), a flexible cold-applied waterproofing material fully compliant with the national standard 23441-2009. It is made of high-quality polymer asphalt as the core base material, modified by adding special tackifiers. The surface is covered with polyester film (PET polyethylene film (PE) or aluminum-plated polyester film as the facing layer, and the lower surface is equipped with a silicon-coated antihesion release layer. The whole product has no carrier reinforcing structure such as polyesterce. Common thickness specifications include 1.2mm, 1.5mm and2.0mm, the width of each roll is mostly 1000mm, and the area of each roll can be10㎡ or 15㎡.

Product Features

1. The base-material-free structure brings extremely high elongation. national standard requires the ultimate elongation of Class N products to be ≥150%, which can fully adapt to the expansion and cracking deformation of base layer. Its ability to adapt to structural deformation is far superior to similar waterproof with base materials.

2. The self-adhesive performance is strong, and it remains a viscoelastic state for a long time, forming a "skin-like full adhesion effect" with the base layer, fundamentally eliminating the hidden danger of waterepage between the waterproof layer and the base layer. Meanwhile, it has a built-in "self-healing" function that can selfpair tiny holes with a diameter ≤2mm.

3. Full cold construction requires no open flame, no additional coating, it is low-carbon, environmentally friendly and free from open flame risks, especially suitable for waterproofing operations in fire-ban areas. construction efficiency is over 50% higher than that of traditional hot-melt waterproof membranes.

4. Excellent low-temperature flexibility: no cracks when bent -20℃ (Type II products can reach -30℃). It has outstanding weather resistance, with stable high/low temperature, aging resistance and puncture resistance. Some customized models can also achieve special properties such as root resistance and chemical corrosion resistance.

5. Low requirements for base surface: it can be directly constructed by the wet-laying method on a damp base surface without standing water, and there is no need to wait for base layer to be completely dry, which greatly shortens the construction period.

Product Uses

 1. Applicable to non-exposed roof waterproofing projects for industrial and civil buildings, and can also be used as a hidden waterproof layer in wall waterproofing scenarios.

2. Widely suitable for waterproofing and seage control works of underground engineering such as basements, civil air defense projects, tunnels, etc. The pre-laid type can be directly laid on the cushion layer before concrete, achieving full bonding between the waterproof layer and the structural layer.

3. Can be used for moisture-proof and waterproof projects in special places such as depots and electronic workshops that are sensitive to moisture, avoiding moisture penetration from affecting internal materials and precision equipment.

4. Suitable for parts in coastal areas saltwater corrosion and large structural deformation, as well as waterproofing and seepage control works of municipal engineering such municipal canals, reservoirs, swimming pools, etc.

5. Especially applicable to areas where open flames are strictly prohibited on construction sites, and waterproofing construction in low-temperature and cold regions, avoiding safety hazards brought by hot melt construction and difficulties in low-temperature construction.
