VABREN supplied geosynthetic clay liner (GCL) for an artificial lake seepage-control project in Guang'an. Project photographs dated 14 August 2025 record panels across the basin, workers fitting liner around a concrete structure, and night-time earthworks and cover placement. The broad lining area and the more detailed work at a local structure appear within the same set of site records.
An artificial lake brings these tasks together. Rolls cover the open basin in adjacent panels, while seams and structure transitions need their own place in the installation sequence. Considering these areas alongside the cover works helps procurement and construction planning work from the same basin layout.
Building the lake lining with adjacent GCL panels
The wide site view shows white GCL across the basin, with panel edges and seam lines visible. Roll supply allows the open lake floor to be organized into installation areas. The same layout also needs to show how panels continue at boundaries, corners and the structures within the basin.
GCL combines bentonite with geotextiles. Under suitable water and confinement conditions, the bentonite forms a barrier with low permeability. During placement, the overlaps between panels are part of the continuity of that barrier. Panel direction, side overlaps, end overlaps and seam treatment therefore need to be defined before deployment and checked as the panels are positioned.
For ordering, the lake's plan area is a starting point. Material quantities also need to account for the basin and slope surfaces, overlaps, boundary terminations and cuts at structures. Reviewing roll dimensions against the layout helps identify where additional pieces are needed and where cutting allowances arise.
Fitting GCL around a concrete structure
A closer night-time view shows workers positioning GCL around a concrete structure in the basin. As the panels reach this local detail, the working space becomes tighter and edges, corners and connections come closer together. The fit at the structure and its termination need to be considered alongside continuity with the surrounding panels.
When preparing a similar detail, identify where the liner meets the structure and how the cut panels connect to the surrounding lining. Sealing materials, local reinforcement and fixing arrangements need to suit the selected GCL and the connection design. Listing these items in advance also brings the required accessories into purchasing and delivery planning.
Coordinating seam checks with the earthworks
The Guang'an photographs place the lining area alongside the earthworks. While panels are exposed, their seams remain accessible for inspection. This is the stage to review overlap continuity, clean the contact areas and check structure connections and local repairs before they become concealed.
Cover placement changes what remains visible and introduces the movement of soil delivery and spreading equipment. Identifying the areas laid, awaiting inspection and awaiting cover helps organize equipment routes and the handover between tasks. At night, lighting should reach seams, corners and the cover front so panel edges and equipment movements can be seen clearly.
Placing cover over the GCL lining
Another night-time photograph shows a loader placing cover over part of the lined basin. Cover protects the material and provides confinement for the GCL. For construction planning, the cover material and equipment working method need to be considered alongside the liner deployment schedule.
During spreading, keep panels and overlaps in position and keep soil out of open seam areas. Equipment needs to work on the protective layer required for the project, using suitable delivery and spreading routes. Define cover thickness, soil requirements and equipment access in the project cover plan so material protection is carried through into the working method.
Preparing GCL supply for another artificial lake
The Guang'an site brings several typical lake details into one view: the open basin, panel seams, a concrete structure and the advancing earth cover. For a similar project, organizing drawings and details around these locations helps connect roll supply and accessory requirements with their use on site.
For panel deployment and overlap preparation, continue with the GCL installation and overlap guide. The Baiyun District supply project in Guangzhou focuses on delivered rolls, field sampling and testing records. It adds a further view of the material procurement process for an artificial lake.

For artificial lake GCL supply, send VABREN the basin plan and sections, water conditions, structure details, cover design and estimated quantity. These documents provide a basis for discussing liner construction, roll dimensions and delivery requirements in relation to the installation layout.
