W-shaped Drainage Shock-absorbing Pad Auxiliary Material

1. Dual-Function Engineered Structure

The W-type polymer core paired with 80–150g/m² stitchbond fabric creates a hybrid system:

500mL/min/㎡ drainage capacity (3x faster than flat membranes) via 3–5mm vertical channels, eliminating waterlogging in 10+ mm/h heavy rain.

Surface stitchbond layer filters ≥95% of ≥0.5mm particles (ASTM D2419), preventing drainage system clogs while enhancing load distribution.

2. Extreme Climate Durability

Withstands -30°C to 70°C temperature cycles without embrittlement or deformation, outlasting standard non-wovens by 20% in freeze-thaw zones.

UV-resistant additives ensure ≥90% tensile retention after 500 hours of UV exposure (ASTM G154), ideal for rooftop gardens or sunny balconies.

Compliant with GB/T 23458 for long-term performance in wet, high-traffic environments.

3. Vibration Mitigation & Structural Protection

Engineered to reduce impact transfer by 40% (ISO 140-8 testing), protecting brittle finishes like ceramic tiles or natural stone from cracking under foot traffic or heavy loads.

150N/5cm longitudinal tensile strength (ASTM D882) resists tearing during installation, 30% stronger than generic non-woven pads.

5–10mm thickness balances cushioning and drainage efficiency for the optimal load-bearing solution.

4. Lightweight & Installation-Friendly Design

At 300–500g/m², it’s 50% lighter than cement-based drainage layers, cutting transportation costs and roof load—critical for retrofit projects or lightweight structures.

Self-adhesive edges or mechanical fastening compatibility shortens installation time by 30%, with no special tools required.

Customizable rolls (1–2m width) fit complex geometries in bathrooms, terraces, or green roofs.

5. Eco-Compliance & Sustainable Performance

Made from 100% recyclable polypropylene, the stitchbond fabric contains zero VOCs (SGS-certified) and meets OEKO-TEX Standard 100 for safe indoor use.

Fully recyclable at end-of-life, aligning with LEED v4 and China Green Building Criteria for sustainable drainage solutions.

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.

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.

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.

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.

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.
