Composite drainage board
Composite drainage board, also known as three-dimensional composite drainage network, drainage grid, is a new type of drainage geomaterials. It is composed of one or two layers of non-woven geotextile and one layer of three-dimensional synthetic geomesh core with different structures, and has the function of drainage isolation.

Looking to protect your foundation, roofing system, tunnel, or green roof from water buildup, seepage, and hydrostatic pressure? The composite drainage board is your go-to solution. Designed with precision engineering, this high-performance material provides outstanding drainage, filtration, and protection—all in one.
Whether you're managing moisture beneath a parking deck or ensuring longevity for your landscaping projects, a composite drainage board is an essential investment for long-term durability.
What Is a Composite Drainage Board?
A composite drainage board is a multi-layered geosynthetic material made from a core drainage layer (typically high-density polyethylene or polypropylene) bonded with a geotextile fabric. This design allows it to rapidly collect, filter, and transport water, protecting structural elements and maintaining soil stability.
With its strong compressive strength and long service life, the composite drainage board is a reliable barrier against water damage in both residential and industrial applications.
Key Benefits of Composite Drainage Board
✅ Superior Drainage Efficiency
The dimpled or grooved core allows for fast and consistent water flow, ensuring rapid drainage and reducing water pressure on structures.
✅ Integrated Filtration
The bonded non-woven geotextile effectively filters soil particles while allowing water to pass through, maintaining optimal performance over time.
✅ High Compressive Strength
Engineered to withstand high load conditions without deformation—ideal for buried applications or beneath heavy paving.
✅ Cost-Efficient Installation
Lightweight and easy to cut or roll, the composite drainage board saves labor time and cost compared to traditional gravel-based systems.
✅ Long-Term Durability
Resistant to chemicals, root penetration, and soil acidity—ensuring performance for decades even in challenging environments.
Applications of Composite Drainage Board
The composite drainage board is incredibly versatile and widely used across civil engineering, landscaping, and waterproofing projects, including:
✔ Basement walls and foundation protection
✔ Green roofs and roof gardens
✔ Underground parking lots
✔ Tunnel and subway linings
✔ Highway and railway embankments
✔ Retaining walls
✔ Landfills and environmental containment
In each of these use cases, the composite drainage board ensures effective water discharge while providing an additional protective barrier.
