APPLICATION INSTRUCTIONS
Application Materials
Main material
Siphonic composite drainage board
Auxiliary materials
High-strength drainage channels and components, double-sided adhesive tape or non-curing rubberized asphalt waterproof coating, nonwoven fabric of short polypropylene fiber, siphonic drainage pipes, ventilation observation pipes, dust-proof caps, adhesive or adhesive tape, sediment observation wells, etc.
Application tools
Utility knives, brushes, angle grinders, measuring tapes, chalk lines, etc.
Application Process
· Flat Surface Construction:
Clean the substrate → Plan and mark lines→ Apply double-sided adhesive tape or non-curing coating →Lay drainage channels → Install the siphonic composite drainage board → Overlap joints → Adhere geotextile→ Install ventilation components → Install siphonic outlets → Backfill
· Vertical Surface Construction:
Clean the substrate → Plan and mark lines→ Apply double-sided adhesive tape or non-curing coating → Install drainage boards→ Overlap joints→ Seal edges→ Backfill
Application Key point
· Inspect and ensure substrate quality before installation. The substrate must be clean, flat, and free of standing water.
· Drainage boards should be connected using double-sided adhesive tape with a bonding width of no less than 80mm.
· Ensure proper overlap and sealing of geotextiles and drainage boards.
· Follow design and standards for detailing at deformation joints, vertical terminations, and reserved openings.
Product Protection
· Use sandbags or tarpaulins for temporary protection to prevent soil intrusion.
· Backfill immediately after installation; exposure to UV light should not exceed 14 days. Avoid direct contact of construction machinery with the drainage board.
· During the simultaneous laying and filling processes, construction machinery must not come into direct contact. Mechanical equipment should only be placed when the covering soil thickness exceeds 500mm.
ADVANTAGES
Product Advantages
· Made from virgin HDPE resin, offering excellent low-temperature resistance, corrosion resistance, durability, high tensile strength, and superior compressive performance.
· Nonwoven fabric made of short polypropylene fibers provides stable performance with strong acid and alkali resistance
· The HDPE drainage panel and geotextile are adhered with specialized adhesive, ensuring high peel strength and stable pressure.
Application Advantages
· Optimized Structure, Cost Saving
Pre-adhered geotextile eliminates the need for traditional layers (e.g., slope correction, leveling, isolation, and protection), significantly reducing material and labor costs.
· Efficient Process, Environmentally Friendly
The drainage panel, manufactured using virgin HDPE resin, is directly installed on the waterproof layer, simplifying and accelerating installation.
· Organized Drainage, Enhanced Reliability
Rainwater infiltrates through the drainage board and is guided to siphonic outlets, transforming passive drainage into active pressured drainage, improving efficiency.
· Integrated Drainage and Protection
The drainage board is in direct contact with the waterproofing system. As a drainage component under vegetation areas, it reduces the risk of roof leakage during planting, protects plant roots, and improves the survival rate of greenery, meeting the requirements of SGBC and Sponge City standards.
