W-shaped Drainage Shock-absorbing Pad Auxiliary Material

The W-type drainage pad is a lightweight, multi-functional underlayment designed for green roofs, bathrooms, balconies, and commercial flooring systems. Unlike conventional shock pads used in sports flooring, this product focuses on rapid drainage, waterproofing, and vibration reduction. Its polymer W-core and stitchbond surface layer create a three-in-one solution: water drainage, load distribution, and cushioning for brittle finishes like ceramic tiles or natural stone.

Product Advantage

Product Advantage

1. Dual-Function Drainage & Filtration

  • 500mL/min/㎡ drainage rate through 3–5mm vertical channels – 3× faster than flat membranes, preventing waterlogging during heavy rain (>10mm/h).

  • The stitchbond surface filters ≥95% of particles ≥0.5mm (ASTM D2419), keeping drainage systems clean while spreading load evenly across the floor.

2. Extreme Climate Durability

  • Works from -30°C to 70°C without cracking or deformation, outperforming standard non-wovens in freeze–thaw zones.

  • UV-resistant additives retain ≥90% tensile strength after 500 hours of exposure (ASTM G154), ideal for rooftop gardens and outdoor walkways.

  • Certified to GB/T 23458, ensuring long-term stability in wet, high-traffic environments.

3. Vibration & Impact Mitigation

  • Reduces vibration transfer by 40% (ISO 140-8), protecting finishes like marble, tile, or engineered wood.

  • ≥150N/5cm tensile strength resists tearing during installation, 30% stronger than generic non-woven underlayment.

  • Thickness options (5–10mm) balance drainage efficiency with shock absorption.

4. Lightweight & Easy Installation

  • At 300–500g/m², it’s 50% lighter than cement-based drainage layers – reducing roof load and transport costs.

  • Compatible with self-adhesive edges, screws, or bonding adhesives, cutting installation time by up to 30%.

  • Roll widths (1–2m) adapt to complex spaces in bathrooms, terraces, or lightweight structures.

5. Eco-Friendly Construction

  • Made from 100% recyclable polypropylene, free of VOCs, SGS-tested and OEKO-TEX 100 certified.

  • Meets LEED v4 and China Green Building standards, offering sustainable drainage solutions for modern projects.

Product Uses

Product Uses



Residential Bathrooms & Balconies


Ideal for wet areas with tile/stone flooring, the pad’s 500mL/min/㎡ drainage rate quickly removes shower water or rain, while the 40% vibration reduction protects grout from cracking under foot traffic. The stitchbond filter layer blocks hair/sediment, preventing drain clogs in long-term use.


Rooftop Gardens & Green Roofs


In rooftop ecosystems, the -30°C to 70°C Temperature resistance and ≥90% UV resistance ensure durability under plant roots and seasonal temperature swings. Lightweight (5–10mm thickness) to reduce roof load, it channels excess irrigation water while cushioning delicate vegetation roots.


Commercial Flooring (Malls, Offices)


High-traffic zones benefit from 150N/5cm tensile strength and 200kPa compressive resistance, resisting tears and deformation under rolling loads. The 40% shock absorption mitigates stress on luxury finishes like marble or engineered wood, extending service life by 20%.


Infrastructure & Outdoor Walkways


Used beneath pavers or decking in plazas/pool areas, the pad’s W-type channels handle 10+ mm/h heavy rain, preventing surface flooding. Its 10+ year outdoor lifespan and resistance to chlorinated water (pool environments) make it a low-maintenance choice.


Retrofit Projects & Lightweight Structures


For old house renovation or light steel roof,the 300–500g/m² weight (50% lighter than concrete alternatives) reduces structural load. Easy installation via self-adhesive edges cuts labor time by 30%, compatible with existing tiles, metal sheets, or composite decks.


Industrial & Utility Areas


In machine rooms or storage facilities, the pad dampens vibrations from equipment, protecting epoxy floors from stress fractures. Its ≥95% particle filtration prevents dust/debris from clogging drainage systems in high-dust environments.


FAQ

FAQ



Q: How do I choose the right thickness for my project?

A: Select 6mm for light loads (bathrooms, balconies), 8mm for moderate loads (rooftop gardens, commercial floors), or 10mm for heavy-duty use (industrial areas, playgrounds). All offer 500mL/min/㎡ drainage and 40% vibration reduction.


Q: Can the 10mm pad withstand heavy machinery or vehicle traffic?

A: Yes, the 10mm thickness provides 200kPa compressive strength (ASTM D695), ideal for industrial floors or driveways, resisting deformation under heavy loads while maintaining efficient water drainage.


Q: Is installation different for each thickness?

A: No, all 6mm, 8mm, 10mm pads use the same easy methods: self-adhesive edges, mechanical fasteners, or adhesive bonding. Customizable rolls (1–2m width) fit any space without special tools.


Q: How does thickness affect performance in cold climates?

A: All thicknesses withstand -30°C to 70°C, with ≥90% tensile strength after UV exposure (ASTM G154). Thicker pads (8mm/10mm) offer slightly enhanced shock absorption for icy, high-impact environments.


Q: Are the different thicknesses environmentally friendly?

A: Yes, all 6mm, 8mm, 10mm pads are made from 100% recyclable polypropylene and OEKO-TEX certified (no toxins), compliant with LEED and China Green Building standards for sustainable projects.
