Heavy-Duty Water Drainage Geocomposite Mat Slope Protection Mat Geonet

Product Description

Product Description

It is a new type of composite reinforced geonet mat, which combines the three-dimensional geonet mat with the twisted hexagonal metal mesh of various coatings through special technology and equipment.

Specification
(1) The tensile strength of the mesh surface is 35KN/m, in line with the EN10223-3 standard
(2) coating adhesion requirements: The adhesion test of the plated Galfan layer adopts the winding test method, and should meet the following standards, when the plated Galfan steel wire is tightly wrapped around the mandrel equivalent to 2 times its own diameter for 6 circles, rubbing the steel wire with your fingers, the coating will not flake or crack.
(3) Steel wire rope: nominal tensile strength is not less than 1770MPa, AB class hot dip galvanized anticorrosive treatment.
(4) Bolt: A single double-strand wire rope bolt with a diameter of not less than Φ16 should be used, with the length of the upper anchor rod being 3m and the length of the lower anchor rod being 2m.

FAQ

1.Textured or Smooth hdpe Geomembrane?
A textured product is either needed or is not. This apparent truism needs to be remembered in many cases in which a product is specified for a project which clearly does not qualify to be designated as textured yet is designated as such, creating a huge confusion about the uncertainty of the client's needs.
If the client does not clarify they require, it is hardly feasible to offer the right solution in conditions comparable to any concurrent company.

2.Is a hdpe Geomembrane with a wider roll better?
There is a technical limit for manufacturing geomembranes. In high density polyethylene (HDPE), this is 7.5 to 8m. Beyond this limit, either the raw material is not an HDPE and is instead a softer material which enables the extrusion-header system of the machine to complete the geomembrane transformation cycle, or the uniform thickness or thermal treatment parameters of the raw material have been seriously compromised. Within these limits and exceeding a minimum width, under which it would be unreasonable to present a product for the Safe Containment application, the roll width is the choice of the manufacturer, usually subject to the presentation format and transport cost optimisation.
There is hardly any difference between the cost of machines for given widths.
Within these limits, it is true that a wider roll relieves installation costs in large projects by a small percentage; however it is always at the expense of a higher cost of handling bulk unit weight of the roll or overruns in the finishing of curves or corners.

3.Differences between LLDPE  and HDPE geomembrane?
Linear low density polyethylene (LLDPE) and high density polyethylene (HDPE) are raw materials which are similar in terms of composition, but very different in their behaviour, as has already been discussed in previous sections.
HDPE has become a global standard for Safe Containment applications precisely for its unique properties and marketing an LLDPE as an HDPE in these applications is tantamount to offering a substitute product without any benefit to the client. Differentiating them is very simple.
