How geocell confines soil and aggregate
HDPE geocell is a three-dimensional honeycomb grid that confines fill, increasing shear resistance on steep faces. Strips are ultrasonically welded into expandable cells, anchored on site, and infilled with crushed stone or vegetated topsoil depending on hydraulic exposure.
On Suki Kinari and Diamer Bhasha dam–related zones, geocell works with HDPE geomembrane lining and geotextile separation in staged construction—Petroseal supplies the package to contractors who need coordinated deliveries and technical familiarity with WAPDA-scale specs.
Selecting cell depth and sheet thickness
| Parameter | Typical range | Driver |
|---|---|---|
| Cell depth | 75–200 mm | Slope angle and fill type |
| Welded cell size | 330–660 mm | Panel handling and confinement |
| Sheet thickness | 1.0–1.5 mm | Durability until covered |
Deeper cells suit steeper dam abutments and stone infill; shallower cells may suffice on vegetated upper slopes above full supply level. Anchor spacing follows the engineer's stability calculation—not a universal rule of thumb.
Installation sequence
- Prepare subgrade; place geotextile separator if specified
- Expand geocell panel and anchor per drawing
- Infill in lifts; compact without displacing cells
- Protect from UV until cover soil or riprap is placed
