1.5mm Non‑reinforced Self‑adhesive Polymer‑modified Bitumen Waterproof Membrane

Product Introduction

1.5mm Non‑reinforced (Type N) Self‑adhesive Polymer‑modified Bitumen Waterproof Membrane. It takes SBS polymer‑modified bitumen as the main adhesive compound with non‑reinforced structure. The top surface adopts PE/PET release film, and the bottom surface is covered with silicone oil paper release film. Thickness is 1.5 mm with standard width of 1 m. It features cold installation by pressure‑sensitive adhesion of bitumen. Soft material allows good fitting for irregular details. It belongs to non‑exposed waterproof membrane.

Product Advantages

Safe and convenient cold application. No open‑flame torching required. Install directly by peeling off release film. It eliminates fire risks, shortens construction period and suits fire‑prohibited job sites.

Ultra‑high elongation and soft texture. It adapts to substrate cracking and deformation, and fits well for irregular positions such as internal‑external corners and pipe roots.

Strong bonding performance and anti‑water‑channeling property. It adheres tightly to concrete and cement‑mortar substrates, effectively reducing water channeling risks with reliable lap sealing.

Excellent self‑healing performance. The self‑adhesive bitumen can automatically seal tiny nail holes and puncture damages, delivering good nail‑rod water tightness.

Stable high‑low temperature performance. Heat‑resistant without flowing, good low‑temperature flexibility, applicable for both northern and southern regions.

Available for composite waterproofing. It can be used together with waterproof coatings to meet medium‑to‑high‑grade waterproofing requirements.

Application Scenarios

Non‑exposed roof waterproofing and moisture‑proofing for industrial and civil buildings.

Underground waterproof parts including basement slabs, side walls and civil air‑defense works.

Anti‑seepage and moisture‑proofing for pools, water channels, garage top slabs and municipal pipe trenches.

Waterproof construction sites where open‑flame operation is forbidden, such as chemical plants and oil depots.

Renovation and maintenance projects for old roofs.

Can be combined with waterproof coatings to form composite waterproof systems.

Note: This is non‑exposed membrane. Protective layer shall be applied after installation. Long‑term direct sunlight exposure is prohibited.
