1. Efficient Water Conductivity: Water conductivity is 5-10 instances higher than common gravel layers, saving space.
2. Compression Resistance and Durability: HDPE material withstands a compressive load of ≥300kPa and has a lifespan of over 50 years.
3. Easy Installation: Rolled fabric design (1-3m width) approves for fast set up and reduces labor costs.
4. Energy-Saving: Reduces gravel mining and complies with green constructing standards (such as LEED certification).
5. Multifunctional Integration: Can contain waterproofing, reinforcement, and other features to meet complex engineering requirements.
Introduction
Drainage Composite Sheet is a enormously high quality drainage fabric extensively used in civil engineering, architecture, and panorama design. Typically composed of more than one layers of practical materials, it serves to information water, stop seepage, and supply structural protection. Similar merchandise such as Plastic Drainage Board, HDPE Drainage Board, or Geocomposite Drainage Board provide comparable functions, but their particular constructions may additionally fluctuate relying on particular needs.

Typical Application
1. Building Waterproofing: Basement Waterproofing and Drainage, Roof Garden Drainage: Composite Drainage Board + Impermeable Membrane
2. Road/Railway Subgrade: Prevents water accumulation and softening of the foundation, bettering stability: HDPE Drainage Mat (High Compression Resistance)
3. Retaining Walls/Slopes: Reduces hydrostatic stress and prevents landslides: Geocomposite Drainage Board (Dual-Sided Filtration)
4. Landfills: Leachate Collection and Drainage: Chemical-Resistant Drainage Board
5. Sports Fields/Golf Courses: Rapid Drainage to Prevent Water Accumulation and Impact on Use: Lightweight Plastic Drainage Board
6. Tunnel Engineering: Drainage Behind Lining to Reduce Water Pressure: Drainage Protection Board (Puncture-Resistant)

Core Features
1. High-efficiency Drainage: Water conductivity ≥ 0.5 cm²/s, fantastically giant than each and every and each and every day gravel drainage layers (0.01-0.1 cm²/s).
2. High Compressive Strength: Compressive electrical electricity ≥ 300 kPa (e.g., HDPE Drainage Board), pinnacle notch for high-load factors such as roadbeds and basements.
3. Anti-clogging Design: A geotextile filter layer (Ø₉₀ ≤ 0.1 mm) effectually prevents sediment accumulation.
4. Seepage & Waterproofing: A composite anti-seepage membrane (e.g., Drainage Board Waterproofing) achieves built-in drainage and waterproofing.
5. Chemical Resistance: The HDPE/PP material is acid- and alkali-resistant, making it awesome for harsh environments such as landfills and chemical plants.
6. Lightweight & Straight in Prolong to Install: Weighing barring a doubt 1.5-3.0 kg/m², it extraordinarily reduces transportation and set up costs.

Core Composition Structure
1. Drainage Core Layer
Material: HDPE (high-density polyethylene), PP (polypropylene), etc., corrosion-resistant and pressure-resistant.
Structure: three-dimensional mesh (such as HDPE Drainage Mat), porosity ≥80%, water conductivity ≥0.5 cm²/s.
Thickness: usually 5mm~20mm (can be customized according to project requirements).
2. Filter Layer
Material: polyester non-woven geotextile (100~300g/m²), permeable but blocks fine particles.
Function: prevent soil and sediment from entering the drainage channel, ensuring long-term patency.
3. Anti-seepage Layer
Material: HDPE anti-seepage membrane (0.5~2.0mm thick) or composite waterproof coating.
Applicable scenarios: basements, roof gardens and other projects that require waterproofing.
