GEOSYNTHETICS SOUTH AFRICA
GS HDPE Geocell
Geosynthetics South Africa supplies and installs GS HDPE Geocell cellular confinement systems for road bases, working platforms, slopes, channels and engineered infill protection. Expanded HDPE panels confine the infill, helping distribute loads and control movement within the designed layer.

What GS HDPE Geocell does
Geocell panels expand into a three-dimensional cellular structure. The cells hold selected granular, soil or concrete infill in position. Cell depth, weld spacing, infill, anchoring and the supporting ground determine the system’s suitability for the application.
We supply the GS445 and GS712 ranges with the specified panel configuration and accessories. Panels have a nominal expanded size of 3 m × 11 m (33 m²); confirm the expansion geometry and effective coverage for your layout.
Applications
- Road bases, haul routes, access roads and load-support platforms.
- Slope and embankment surface protection with the specified infill and anchors.
- Drainage channels and erosion protection works.
- Engineered cover layers above geomembranes, with a separately designed protection layer and installation method.
- Retaining and gravity structures designed for the actual soil, loads and geometry.

Installation and accessories
We can provide panels, joining components, specified tendons and ground anchors, with geotextile underlays where required by the design. Installation includes ground preparation, panel expansion, connections, anchoring, controlled infill placement and compaction. Avoid trafficking unfilled panels or placing infill in a way that damages the geocell or underlying liner.
