TEXTURED GEOMEMBRANE
Textured HDPE Geomembrane
An HDPE geomembrane family with textured surfaces available in spray-textured and column-point forms for seepage-control applications and project contexts requiring increased surface interaction.
PRODUCT OVERVIEW
Two Textured Surface Forms within the HDPE Geomembrane Family
Textured HDPE geomembrane is available in spray-textured and column-point forms. The two forms use different surface-forming processes and have distinct dimensional ranges.
Single-textured and double-textured forms are available. Models GH-2T1 and GH-2T2 are listed for the family; project selection should confirm the required surface configuration without assigning either model to a specific side configuration.
SURFACE TYPES & MANUFACTURING
Separate Processes and Dimensional Ranges
Review the surface form, thickness, width and project design requirements together before product selection.
Spray-Textured
A smooth HDPE geomembrane base receives secondary spray roughening using a geomembrane spray-roughening unit.
- Thickness
- 0.5–3.0 mm
- Width
- 4–8 m
- Length
- According to engineering design and customer requirements
Models: GH-2T1 / GH-2T2. Reference noted for the spray-textured form: GRI-GM 13.
Column-Point Textured
Special-formula virgin resin is processed through special flat extrusion to form a uniform-height column-point appearance.
- Thickness
- 0.8–3.0 mm
- Width
- 1–7 m
- Length
- According to engineering design or customer requirements
Models: GH-2T1 / GH-2T2. Please specify the required surface configuration with the inquiry.

SELECTION CONSIDERATIONS
Information to Define Before Product Selection
Align the requested product form and dimensions with the project design and installation context.
Surface Form
Confirm whether the requirement calls for spray-textured or column-point material.
Surface Configuration
State whether a single-textured or double-textured form is required.
Thickness
Provide the required thickness together with the selected product form.
Width
Confirm the required roll width within the relevant form’s listed range.
Installation Context
Share slope, stepped-slope, vertical or other project laying requirements.
Procurement Requirement
Provide application, quantity and project requirements for quotation review.
MANUFACTURING & QUALITY
Process Context for the Selected Surface Form
Spray-textured material uses secondary roughening on a smooth HDPE geomembrane base. Column-point material is described as being produced through special flat extrusion.
- Confirm the required textured surface form.
- Review thickness and width against the relevant form’s listed range.
- Align project requirements with the reference standards and contract.
