Geomembrane

Geotextile is also called anti-seepage geomembrane

Because the plastic geotextile in the construction process, the polymer high score guild starts from the first row in the direction of thermal extension, which enhances the bond between the branches and realizes the compressive strength to catch up. Its elongation is only 10%~15% of the original single. If participating in geotextile anti-aging materials such as carbon black, it can make it have excellent acid resistance, alkali resistance, corrosion resistance and long-term anti-aging functions.

The anti-seepage geomembrane is made of high-count polymers, extruded into thin plates, then punched into the mesh and stretched longitudinally. In this process, the high-branched polymer develops in the linear direction in the future, resulting in an overall layout of a long oval grid with even distribution and high node compressive strength.



Geotextile is also called anti-seepage geomembrane. The custom of geotextile is called waterproof board. It is a kind of anti-seepage material made of polymer materials.
The prerequisite for the selection of anti-seepage geomembrane is that the geotextile can be adopted by the equipment before being poured into the concrete by the secondary lining form and will not be damaged. Durability of the material; the implicit seam of the board is close to reliable; easy to operate; economical.
In addition, in order to prevent the sprayed concrete from penetrating the waterproof board, a non-waterproof cloth pad is set inside the waterproof board as a protective layer, which is used for protection, filtration and necessary drainage.
The equivalent pore size and permeability coefficient of geotextiles are usually selected from the retained soil specification and the water transfer specification, and the correlation between the equivalent pore size of the geotextile and the characteristic particle size of the soil is constructed.
