Product Description

In drainage infrastructure such as railways and highways, the Composite drainage pad has a close relationship with the safety and service life of the project and its own drainage system. The drainage network is an important part of the drainage system.
Composite drainage pad is a new type of drainage geotechnical material. It is made of high-density polyethylene (HDPE) through a special extrusion molding process and has a three-layer special structure. The middle ribs are rigid and arranged longitudinally to form drainage channels, and the ribs arranged up and down form a support to prevent geotextiles from being embedded in the drainage channels, and can maintain high drainage performance even under high loads. The double-sided adhesive water-permeable geotextile is used in combination, and has the comprehensive performance of "reverse filtration-drainage-ventilation-protection". It is currently the most ideal drainage material.


Composite drainage pad Features:

1. Strong drainage (equivalent to one meter thick gravel drainage).
2. High tensile strength.
3. Reduce the probability of geotextiles being embedded in the mesh core and maintain long-term stable drainage.
4. Long-term high-pressure load (capable of compressing load of about 3000Ka).

5. Corrosion resistance, acid and alkali resistance, long service life.
