Product Details

Product Introduction:
The Composite W-shaped drainage pad is composed of two layers of non-woven fabric combined with a central drainage core board. The drainage core board is formed by special extrusion of polypropylene as the raw material to form a "wave" shaped longitudinal full section continuous drainage channel. Due to the continuous and linear channels inside the drainage core board, the horizontal levels in different channels do not interfere with each other, allowing the seepage water flow to pass through at a fast speed, thus achieving good drainage effect. The upper and lower composite layers of non-woven fabric play a filtering role, ensuring that no particles enter the drainage channel to block the channel in practical engineering applications, ensuring that the soil structure is complete and does not cause structural deformation or collapse. In projects with special anti-seepage requirements, a composite layer of geomembrane can be chosen to play a role in anti-seepage. Therefore, this product actually combines three functions of drainage, filtration, and anti-seepage, and is a typical multifunctional material.
Product specifications:
The thickness of the mesh core is 3.5mm, 4.5mm, 5.5mm, 6.5mm, 7.5mm, and 8.5mm.
Application scope:
1、 Applications in highways and railways:

The application of road median and seepage ditch drainage on both sides of the road;
Application in drainage behind retaining walls;
Dredging the stress in the slope ;
Application in tunnel drainage;

2、 Application in landfill sites:

Collection and discharge of leachate from garbage; 2. Collection and discharge of biogas; 3. Sealing the covering layer of the site.

Product features：

Construction convenience:

The wave shaped mesh core drainage pad is lightweight and does not require machinery, and can be constructed manually; Without the need for advanced technicians or special construction tools, construction can usually be completed with cutting tools, nails, and hammers.
The use of overlapping construction is simple and feasible, ensuring the continuity and convenience of construction 6, and avoiding construction quality issues.

Used for anti filtration and anti-seepage:

The geotextile mesh between two layers of geotextile not only provides drainage channels, but also can be used as reinforcement material to improve soil quality

the physical and mechanical properties of geotextiles.

Geotextiles can play a good role in filtration, ensuring that there is no soil erosion during drainage and maintaining soil retention Good.
One layer of geotextile can be replaced with geotextile membrane to achieve anti-seepage effect. 4) Compared to traditional drainage pads, the main feature of corrugated mesh core drainage pads is that the drainage channels are continuous straight lines and do not interfere with each other, achieving good drainage effects.
