2.0mm Polyester Reinforced Self-adhesive Polymer Modified Bitumen Waterproof Membrane

Product Introduction

Sand‑surfaced 2.0mm Self‑adhesive Polymer‑modified Bitumen Waterproof Membrane. It adopts polymer‑modified bitumen as the self‑adhesive compound. The top surface is covered with fine sand protective layer, and the bottom surface is equipped with silicone oil paper release film. With a thickness of 2.0 mm and standard width of 1 m, it enables cold‑applied installation relying on the pressure‑sensitive adhesion of bitumen compound. The fine‑sand surface improves friction resistance and foot‑traffic resistance, reducing damage to the waterproof layer during construction. It is mainly applied for non‑exposed waterproof projects.

Technical Specifications

Product Advantages

1. Safe and eco‑friendly cold application. No open‑flame torching required. Simply peel off the release film for direct installation. It eliminates fire hazards, suitable for fire‑prohibited construction sites, featuring easy operation and shorter construction period.
2. Excellent sand‑surface protection. The fine‑sand top layer resists foot traffic and friction. The waterproof layer is less prone to scratch during construction, lowering risks of later‑stage damage and leakage.
3. Outstanding bonding performance. It bonds firmly to concrete and cement‑mortar substrates. Self‑adhesive sealing on overlaps prevents water channeling and ensures good integrity of the waterproof system.
4. Self‑healing property. When subjected to minor punctures or nail holes, the self‑adhesive bitumen compound can seal tiny defects automatically for enhanced waterproof reliability.
5. High elongation and good low‑temperature flexibility. It accommodates substrate cracking and shrinkage deformation. Suitable for both northern and southern regions and resistant to brittleness at low temperatures.
6. Stable water and moisture resistance. Excellent water impermeability and strong anti‑seepage capacity with long‑lasting material performance.

Application Scope

1. Non‑exposed roof waterproofing and moisture‑proofing for industrial and civil buildings.
2. Underground waterproofing for basement slabs, side walls, civil air‑defense works and other underground structures.
3. Anti‑seepage and moisture‑proofing for pools, water channels, garage top slabs, municipal pipe trenches and similar works.
4. Renovation of old roofs and construction sites where open‑flame operation is forbidden.
5. Can be combined with waterproof coatings to form composite waterproof systems to meet medium‑to‑high‑grade waterproofing requirements.

Note: The sand‑surfaced 2.0 mm self‑adhesive polymer‑modified bitumen membrane shall NOT be directly exposed to long‑term sunlight. A protective covering shall be applied after installation.
