High Strength Geocomposite Drainage Net for Subsurface Drainage

High-Efficiency 3D Drainage:

The robust net core provides a continuous, high-capacity drainage channel that quickly collects and discharges seepage, rainwater, and gases from the soil, effectively reducing pore water pressure.

Excellent Filtration：

The bonded non-woven geotextile allows water to pass freely while effectively preventing soil particles from intruding into the drainage channel, preventing clogging and ensuring the long-term effectiveness of the drainage system.

Dual Protection Function:

 The geotextile and net core together form a cushioning protection layer, effectively preventing punctures to overlying materials (e.g., geomembranes) from sharp gravel, thereby extending the service life of the engineering structure.

Strong Chemical & UV Resistance: 

 Made from chemically inert polyethylene (PE) and polypropylene (PP) materials, it is resistant to acid, alkali, and UV degradation, making it suitable for a variety of complex and harsh environments.

Landfills & Tailings Dams：

Used between the primary and secondary liner systems as a leachate collection layer (LCS) to quickly collect and remove leachate, protecting the geomembrane liners.

Tunnels & Underground Works：

Installed between the primary and secondary tunnel linings or behind the waterproofing layer to form a circumferential drainage system, effectively removing groundwater and ensuring a dry and safe tunnel structure.

Building Basements & Green Roofs：

Used on the external side of basement walls or above the roof waterproofing layer to relieve hydrostatic pressure from the soil and protect the waterproofing layer from backfill damage.

Sports Fields & Landscaping：

Installed beneath the sub-base to ensure proper drainage, prevent waterlogging, and maintain a stable and dry surface.
