Due to the selection of polymer materials and the addition of anti aging agents in the production process, it can be used in unconventional temperature environments.
It is commonly used for seepage prevention treatment of embankments, drainage ditches, and anti pollution treatment of waste disposal sites.
“Two cloths and one membrane” is an impermeable material made of plastic film as the impermeable substrate and thermally compounded with geotextile.
In terms of actual quality control, it is necessary to strictly understand the leveling requirements for construction parts, and the overall waterproof effect will also be better and better.
Of course, after being put into use, there has been a significant improvement in the quality of waterproof works, but related quality control needs to be done during the construction process of this material.
The fabrics used in two fabrics and one film include: short fiber geotextile, filament geotextile, woven fabric, etc.
After improving the quality control standards in recent years, this method should also be strictly mastered during construction.
Specification of two cloth and one film: width: 1-6m, roll length: 50-100m, mass per unit area: 300g to 2800g/m2.
Only after obtaining the relevant construction process permission can construction be carried out, in order to ensure the overall quality of waterproof engineering, it can be seen that the waterproof advantages of this material are increasing.
For construction sites, the composite geotextile material of two cloth and one membrane must be constructed on a flat and dense surface to have better waterproof and impermeable properties.
“Two cloth and one membrane” is one kind of composite impervious geomembrane.
What specific methods can be used for reference? Productive testing.

So, when promoting waterproof materials in the market, most customers also rely on quality.
Use of two cloth and one film: for various reinforced seepage prevention projects such as water conservancy, transportation, tunnels, airports, metallurgical tailings, garbage disposal sites, roof seepage prevention, etc..
.
No matter what kind of project it is When two cloth and one film materials are needed, production type tests are required.
Its impermeability mainly depends on the impermeability of the plastic film.
The joint methods of two cloth and one film include: ① overlapping: the overlapping width should be greater than 15cm; ② Hot welding: Suitable for slightly thick geomembrane substrate, with a weld overlap width of not less than 10cm.
