JX103 Non‑bitumen Polymer Membrane‑based Self‑adhesive Waterproof Membrane is a high‑performance, cold‑applied self‑adhesive polymer waterproof sheet composited of polymer film and premium non‑bitumen adhesive layer via special technology. It features excellent dimensional stability, thermal stability, UV resistance and biaxial tear resistance. Manufactured from high‑quality polymer resin and rubber instead of traditional asphalt substrate, it is non‑toxic, odorless and eco‑friendlier.

Scope of Application

Waterproofing works for basements, subways, tunnels, water tanks, roofs, underground garage slabs, green planting areas, roof gardens and other projects.

Product Specifications

Performance Standard

《Wet installed waterproofing sheets》GB/T 23457‑2025 (P‑Type)

Product Features

‑Reinforced polymer film substrate with thin film delivers higher tear strength and dimensional stability, with better waterproof performance than ordinary films. ‑Cross‑mesh structure effectively solves the bubbling and cracking problem of non‑reinforced HDPE polymer sheets after installation. ‑Outstanding high & low temperature resistance, adaptable to climate changes in hot and cold regions. Great elongation and tensile property to accommodate deformation of structural substrates. ‑The self‑adhesive layer adopts premium resin glue instead of conventional asphalt adhesive. It boasts excellent creep property and strong adaptability to substrate deformation to meet various environmental requirements. ‑Unique puncture resistance, self‑healing property and persistent tear resistance with outstanding nail‑sealing performance. ‑Safe & eco‑friendly. Cold construction shortens project duration and decrease cost, with no environmental pollution and less safety hazards on site.

Construction Process

1.Wet‑laid Workflow

Base cleaning ➔ Substrate wetting ➔ Detail joint treatment ➔ Mark reference lines for membrane laying ➔ Mix & apply cement slurry ➔ Membrane installation ➔ Rolling & venting ➔ Lap seam sealing ➔ Membrane end sealing ➔ Self‑inspection & acceptance ➔ Handover of working surface

2.Dry‑laid Workflow

Substrate preparation ➔ Apply high‑strength adhesive ("Self‑adhesive Companion") ➔ Detail joint treatment ➔ Mark reference lines for membrane laying ➔ Waterproof membrane installation ➔ Lap joint treatment ➔ Rolling & venting ➔ End finishing ➔ Self‑inspection & acceptance ➔ Handover of working surface *For construction method JX112, please refer to Page19/20 of this manual

Transportation & Storage

During transportation and storage, products of different specifications shall be stacked separately without mixing. Avoid sunlight exposure and rain, keep well ventilated and away from fire sources. Storage temperature shall not higher 45℃. Flat stacking height of membranes shall not more than 5 layers; vertical storage shall be single layer. Prevent tilting or side compression during transport, cover with tarpaulin when necessary. Under normal transportation and storage conditions, the shelf life is at least 1 year from production date.
