Introduction: Revolutionize Your Drainage Systems

Are you tired of the complexities and high costs associated with traditional drainage methods like gravel and sand? Meet GeoDrain 3D Composite Drainage Net, an innovative geosynthetic material engineered to provide a complete filtration-drainage-protection solution in a single, easy-to-install product. By combining a robust three-dimensional polymer core with filter geotextiles, it delivers exceptional hydraulic performance and structural reinforcement for a wide range of applications.

What is 3D Composite Drainage Net?

GeoDrain is composed of a three-dimensional network core made from high-density polyethylene (HDPE), thermally bonded on one or both sides with a non-woven geotextile. This unique structure creates an integrated system where:

• The 3D core provides efficient, high-capacity drainage channels.

• The geotextile layers act as a filter, preventing soil particles from clogging the drainage channels while allowing water to pass through freely.

This synergy offers a superior alternative to conventional granular drainage layers, saving time, space, and cost.

Key Features & Unbeatable Advantages

1. Exceptional Drainage Performance

• High Flow Capacity: With an impressive permeability rate (e.g., up to 2500 meters per day under specific gradients and loads), GeoDrain can replace approximately one meter of gravel drainage, offering significant space savings.

• Long-Term Reliability: The supportive upper and lower ribs of the网芯 (network core) prevent the geotextile from embedding into the drainage channels, maintaining consistent and high flow capacity even under immense long-term pressure.

2. Outstanding Mechanical Strength

• High Tensile Strength: The HDPE core offers a high tensile strength (≥36.5 kN/m in some specifications), providing excellent resistance to stretching and tearing during installation and service.

• Superior Load-Bearing Capacity: GeoDrain can withstand enormous compressive loads (e.g., retaining over 60% of its thickness after 10,000 hours under 1200 kPa pressure), making it ideal for heavy-load applications like road bases and landfills.

3. Durability and Chemical Resistance

• Long Service Life: Made from virgin HDPE with added carbon black (≥2%) for UV resistance, GeoDrain is built to last. It is highly resistant to chemical corrosion, alkalinity, and acidity, ensuring performance in harsh environments.

4. Cost-Effective and Easy Installation

• Reduced Material and Labor Costs: By eliminating the need for thick layers of gravel, it cuts material, transportation, and labor expenses.

• Faster Construction: Lightweight rolls are easy to handle, unroll, and connect. This simplicity significantly shortens project timelines compared to traditional methods. Installation involves unrolling, overlapping seams, and securing with staples or connectors.

Versatile Applications Across Industries

GeoDrain is the preferred solution for numerous engineering projects:

• Transportation Infrastructure: Used under road and railway embankments for base and sub-base drainage, extending the structure's lifespan by preventing water saturation.

• Waste Management: Essential in landfills for leachate collection and removal layers, gas collection layers, and as a protective cushion for geomembranes.

• Tunnel and Underground Structures: Provides effective drainage behind tunnel linings and for underground walls, mitigating water pressure.

• Commercial and Civil Projects: Ideal for plaza decks, underground garages, green roofs, and sports field drainage systems.

• Retaining Walls and Slope Protection: Drains water behind retaining walls and stabilizes slopes, reducing the risk of erosion and slippage.

Installation Guide: As Simple as 1-2-3

1. Prepare the Surface: Clear and grade the subgrade to ensure it is smooth and free of sharp debris.

2. Deploy and Connect: Unroll the GeoDrain net with the core's length direction perpendicular to the primary flow of water. Overlap adjacent rolls (typically 300-600 mm for geotextile;网芯 can be connected with plastic clips or polymer ties).

3. Backfill: Carefully place backfill material (e.g., soil, aggregate) directly onto the installed net. No special equipment is needed.

Why Choose GeoDrain?

• Proven Performance: Technical data backed by rigorous testing.

• Comprehensive Solution: Combines drainage, filtration, and reinforcement in one product.
