Question 1

How should a geotextile be selected for project conditions?

Accepted Answer

Selection should consider soil gradation, flow direction, loading, installation stresses and design life together. Polymer, mass per unit area, tensile properties, characteristic opening size and hydraulic properties should be matched to the intended function and applicable specification.

Question 2

How should geomembrane thickness be determined?

Accepted Answer

Thickness is only one design parameter. The contained medium, subgrade preparation, overburden loading, interface conditions, welding process, durability requirements and governing specification all influence selection.

Question 3

Can samples and test documentation be provided before purchase?

Accepted Answer

Samples, routine technical data and releasable inspection documents can be discussed after the preliminary product specification is confirmed. The exact document package depends on the product, applicable standard and contract.

Question 4

Can dimensions and packaging be customised?

Accepted Answer

For selected products, width, roll length, colour, packaging or marking may be adjusted. Minimum quantity, production lead time, container loading and site handling should be confirmed before production.

Question 5

Can you provide installation and welding guidance?

Accepted Answer

We can provide general product installation, overlap, welding and quality-check guidance. Design decisions affecting structural or environmental safety must be confirmed by the qualified project designer and installer.

Question 6

How are export packaging and transport arranged?

Accepted Answer

Packaging and loading proposals are prepared around product dimensions, container utilisation, destination and unloading conditions. Marking and documentation requirements are confirmed before production.

Question 7

How is product quality controlled during production?

Accepted Answer

The control plan should cover raw-material identity, process parameters, dimensions, appearance and relevant product properties. Test methods, sampling frequency and acceptance criteria depend on the product, applicable standard and contract.

Question 8

How quickly can preliminary guidance be provided?

Accepted Answer

When application, specification, quantity and delivery details are complete, the team can first confirm the intended function and product family. Complex projects may require additional review of drawings, interface conditions or standards.
