Self-adhesive waterproofing membrane is a waterproofing material made of self-adhesive rubber asphalt such as SBS, tackifier and high-quality road petroleum asphalt as the base material, strong high-density polyethylene film or aluminum foil as the upper surface material, and peelable silicon-coated isolation film or silicon-coated isolation paper as the anti-adhesive isolation material on the lower surface. The following is a detailed introduction to self-adhesive waterproofing membrane:

1. Types
Self-adhesive waterproofing membranes are mainly divided into two types: self-adhesive with tires and self-adhesive without tires. Self-adhesive with tires is composed of a tire base sandwiched between upper and lower self-adhesives, with an upper covering of ethylene film and a peelable silicone film on the lower covering. Self-adhesive without tires is composed of self-adhesive, upper ethylene film and lower silicone film.

2. Product features
Strong bonding performance: Self-adhesive waterproofing membrane has extremely strong bonding performance and can be firmly bonded to the base layer to ensure waterproofing effect.
Good self-healing performance: It has a “self-healing function” and can heal small puncture damage by itself to maintain good waterproofing performance.
Convenient construction: no adhesive is required, and it does not need to be heated to melt. Just tear off the isolation layer and it can be firmly bonded to the base layer. The construction speed is fast, the construction is safe, and it does not pollute the environment.
Good low temperature resistance: It can adapt to construction in low temperature environments and is the best waterproof, moisture-proof and sealing material for subways, tunnels and non-fire sites.
Corrosion resistance: It has good acid resistance, alkali resistance, and chemical corrosion resistance (except for the surface of the aluminum foil roll), and has excellent aging resistance in various environments.
3. Application scope
Self-adhesive waterproof rolls are widely used in industrial and civil buildings, roofs, basements, indoors, municipal engineering, reservoirs, swimming pools, and subway tunnel waterproofing. At the same time, it is also suitable for waterproofing projects of wooden and metal structure roofs, especially for military facilities that require cold construction and waterproofing projects such as oil depots, chemical plants, textile mills, and grain depots where open flames are not suitable.

4. Precautions
Do not use non-exposed rolls in exposed environments.
Do not lay self-adhesive rolls on frozen base surfaces.
It cannot be constructed on a polluted or high-water-content base.
The packaging and isolation paper of the self-adhesive membrane can only be removed before and during paving.
When the sealant is not used up, the container should be tightened and sealed in time.
The supporting materials of other manufacturers should not be used for this product without verification.
In summary, self-adhesive waterproof membranes occupy an important position in the waterproof material market with their unique performance and wide range of applications. When selecting and using them, they should be reasonably selected according to specific project requirements and construction conditions.
