Technical FAQ – Professional Terminology Explained
Q1: What material grades are used for coating roof waterproofing in industrial scenarios?
A: Main grades include high-purity PVC (polyvinyl chloride), reinforced with glass/polyester mesh. For self adhesive membrane roofing, SBS-modified bitumen with cross-linked polymers is typical. EPDM rubber rolls use a synthetic rubber mix with ≥26% base polymer ratio for ASTM D4637 compliance.
Q2: How is tensile strength determined and why is it crucial?
A: Tensile strength is measured per EN 12311-2 (ISO 527-3) via tensile/flexing machine, indicating force per width (N/50mm or MPa) before break. Higher values signal better mechanical performance, less risk of tearing, and longer durability under load.
Q3: What are the installation standards for PVC With Fiber Composite Backing Sheet?
A: Installation is per EN 13416 and manufacturer guideline: sheets overlapped 50–100mm, joint welding (thermo-weld, solvent) to bond layers, with mechanical fixings if on metal. QA is confirmed by spark leakage testing (EN 1928) and batch inspection reports.
Q4: What defines a membrane as "self adhesive"?
A: A "self adhesive membrane roofing" uses a factory-applied, pressure-sensitive bitumen or synthetic adhesive layer beneath the waterproofing sheet, allowing cold peel-and-stick application, fast installation, and minimal additional tools. EN 13707 standard applies.
Q5: What assurance is available for long-term use?
A: Gardepota offers up to 25 years limited warranty; main products are tested for >5000 hours UV aging and 200 cycles freeze-thaw per EN 1297, EN 13687. All batches have QR-coded traceability for after-sales, including worldwide support and on-site inspection.
Q6: How does EPDM rubber roofing rolls' flexibility compare to PVC membranes?
A: EPDM exhibits higher elongation at break (≥300%) and lower temperature flexibility. However, engineered PVC with fiber composite can match ~200% elongation while offering increased fire retardancy and chemical resistance plus superior dimensional stability (>1.5m width tolerance).
Q7: Which certifications should I look for in reliable coating roof waterproofing?
A: CE (EU), ISO 9001 (quality), ISO 14001 (environment), EN 13956 (plastic waterproofing sheet), EN 13948 (root resistance for green systems), ASTM E108 (fire), and FM Approvals. Always request independent lab (SGS, TUV) certificates for critical projects.
