Advantages & Strengths

3D Drainage:

The upper and lower flat mesh layers and the central ribs form a continuous drainage channel that quickly collects and drains excess water from the soil, reducing pore water pressure.

High Structural Stability:

The three-layer integrated structure resists lateral soil displacement, providing stable support for the engineering structure and preventing localized settlement.

Excellent Reinforcement：

Enhances soil strength and stability, effectively improving the load-bearing capacity of the foundation.

Good Water Permeability:

The pore structure does not hinder water penetration, while preventing soil particle loss and maintaining soil structural integrity.

Strong Environmental Adaptability:

Resistant to acid and alkali corrosion and UV aging, it operates stably in temperatures ranging from -30°C to 60°C, making it suitable for a variety of complex geological environments.

Popular Applications

Subgrade Drainage and Reinforcement uses a 6mm-high tri-plane geonet:

laid within the subgrade filler layer to drain water from the subgrade, while also strengthening the overall strength and preventing deformation and cracking.

Underground Garage Roof Drainage uses a 5mm-high tri-plane geonet:

laid above the roof waterproofing layer to form a drainage layer, quickly draining rainwater or seepage water and protecting the waterproofing layer from water pressure damage.

Sports Field Foundation Drainage uses a tri-plane geonet with a 7mm rib height：

Installed between the gravel base and the soil layer, it drains accumulated water from the field, maintains a dry surface, and ensures safety during play.

Dam Filter Drainage uses a tri-plane geonet with a 8mm rib height：

Installed outside the dam's anti-seepage layer, it acts as a filter to drain seepage water from the dam soil and protect the anti-seepage layer from damage caused by water pressure.
