Drainage Geocomposite

Short Description:

Drainage Geocomposite is available in both single-sided and double-sided products with geonet core thickness from 3mm to 10mm, and fabric ranging from 100gsm to 300gsm. The non-woven geotextile is bonded to the geonet with a hot knife application, allowing for high bond strength without the reduction of transmissivity values of other processes.

Drainage Geocomposite Introduction

Drainage Geocomposite is available in both single-sided and double-sided products with geonet core thickness from 3mm to 10mm, and fabric ranging from 100gsm to 300gsm. The non-woven geotextile is bonded to the geonet with a hot knife application, allowing for high bond strength without the reduction of transmissivity values of other processes.

Drainage geocomposite is the best choice for drainage applications requiring filtration to keep silt and soil particles from clogging flow. This non-woven geotextile has improved friction properties that facilitate its bonding to a geonet core. As a synthetic drainage media, our geocomposite is designed to replace one to three feet of traditional aggregate while providing drainage under various conditions, site loads, and gradients.

The geonet core has two structures. One structure is bi-axial structure and the other is tri-axial structure.

Bi-axial structure / Tri-axial structure:

Directly laying on the ground, instead of the foundation which can dewatering, it can also make the concrete hydrated more evenly and extend the working life of road.

Laying composite drainage network will relieve the influence of frost heaven weather in the cold climate.

Drainage geocomposite specifications:

1. 500g/m2---2000g/m2; geonet core thickness range is 3mm~~10mm.

2. The width range is 2meter-6meters; Maximum width is 6meters; Other width can be custom.

3. The length can be 30, 50meters or as request. Maximum length is depending on the rolling limit.

4. Black color for geonet and white color for geotextile are most ordinary and popular.

Features and benefits

1. High drainage ability (can replace traditional sand, gravel structures or be used together).

2. Good bearing of long-term high-pressured load.

3. High tensile strength and shear strength.

4. Reduce the chance of geotextile embedded network core to protect the long-term stability of the hydraulic conductivity.

5. Excellent chemical resistance characteristics.
