Composite Copper-Based Root Puncture Resistant Waterproof Membrane – Durable & Protective Waterproofing Solution

Product Description

“Younson” physical root-resistant waterproof membrane is based on composite copper, with styrene-butadiene-styrene (SBS) thermoplastic elastomer as a modifier. The upper and lower layers are coated with SBS-modified bitumen containing imported chemical root inhibitors, and both sides are covered with isolation materials. The material combines chemical root resistance and mechanical root resistance by copper, providing excellent puncture resistance, waterproofing, and durability.

Construction Method

Hot-melt construction process: Substrate preparation → Additional layer installation → Hot-melt main surface → Exhaust and compaction → Water test → Protective layer installation

Hot-bond construction process: Substrate preparation → Additional layer installation → Hot-bond main surface → Exhaust and compaction → Water test → Protective layer installation

Transportation and Storage

• Different types and specifications should be stored separately, not mixed;
  
• Avoid sun and rain exposure, ensure ventilation;
  
• Storage temperature ≤ 50℃; store upright in single layers, no more than two layers during transport;
  
• Prevent tilting or lateral pressure during transportation, cover with tarpaulin if necessary;
  

Under proper storage and transport conditions, the shelf life is one year from production date.
