Product Introduction
Description
Water stop membrane is a thin, flexible, and self-adhesive membrane that comes in many sizes. The material has a waterproof layer, which is sandwiched between two layers of protective materials, usually polyester. This composition gives the waterproofing sheet strong physical characteristics and excellent resistance to water and heat.
Features
● The durability of ultraviolet resistance and weathering resistance are long.
● The strong base bonding property is well bonded with a variety of substrates. It can lock the leakage caused by the damage of the coil to a local extent and effectively prevent water from channeling.
● It has good stability, good chemical resistance, simple construction, pressure sensitive bonding and durable and stable waterproofing effect.
Advantage
● It automatically grows with concrete and forms long-lasting bonding effect.
● It automatically heals the damage under φ2mm.
Specification
1mx20m (20M2/Roll), 1.2mm or 1.5mm thickness. Length can be customized.
Main Application
Waterproof and moisture proof works in various parts of the basement, subway, tunnel, pool, civil building and so on.
It is suitable for non-exposed works, and aluminum foil coils are used for exposed works.

Secret Formula
The secret formula for making water stop membrane varies from manufacturer to manufacturer. However, the most common formula involves blending bitumen and polymers in specific ratios, then adding adhesive to create a strong bond with the substrate. The exact formula is closely guarded by manufacturers, which are the leading brands in the market.
