PVC Capillary Drainage Board
The PVC capillary drainage board is an innovative, high-efficiency drainage material made from PVC sheets processed using specialized techniques to form a unidirectional, uniformly distributed capillary groove structure (typically ranging from 0.3 mm to 1 mm in size) on one side, with the other side being a flat surface or composite geotextile. This design combines capillary water conduction and overall drainage functions, effectively guiding and removing excess water from soil or other media.

Key Features and Advantages
High-Efficiency Active Drainage: Unlike traditional gravity-dependent drainage, capillary drainage achieves "active water absorption,"
offering higher drainage efficiency.
Durability and Compression Resistance: The PVC material is corrosion-resistant, acid-alkali resistant, and provides high compressive
strength (exceeding 300 kPa), ensuring long service life.
Lightweight and Eco-Friendly: Lightweight, easy to install, and meets environmental standards.
Integrated Filtration: The composite geotextile filter layer effectively prevents particle intrusion, maintaining long-term drainage performance.
The PVC capillary drainage board represents a technological advancement from passive to active water absorption and drainage, leveraging biomimetic capillary principles. It is particularly suited for complex conditions involving low hydraulic head, slow seepage, and susceptibility to clogging. With its high efficiency, durability, and flexible installation, it stands as an ideal material for addressing drainage and waterproofing challenges in modern construction, infrastructure, and environmental engineering.
