SOLONAX GC
Strips of textured, perforated HDPE ultrasonically welded at regular spacing and expanded on site into a honeycomb mattress. Filled with topsoil, aggregate or concrete, the cells confine the infill laterally: the material can no longer creep down the slope or spread under wheel load, so a thin layer behaves like a much thicker one. Supplied in panels with tendons and anchors for slope work, and in plain panels for load support.
Why it is specified
- Textured cell wall raises the interface friction between the wall and the infill
- Perforations drain the cells laterally and let roots and soil bridge from cell to cell
- Ultrasonic welds tested to EN ISO 13426-1 — junction efficiency is declared, not assumed
- Cell depth selected against slope angle and the angle of repose of the infill, with infill depth de ≥ ½ d
- Tendons and anchor stakes transfer the down-slope load into the crest anchor trench
- On a geomembrane the interface friction drops sharply — anchorage is designed, never copied from a flat-ground detail

Variants
| Code | Description |
|---|---|
| GC-TP | Textured and perforated — the standard grade for slope protection and vegetated surfaces |
| GC-T | Textured, unperforated — where the cell must retain fines or sit on a liner |
| GC-S | Smooth wall — load support over geotextile where drainage is handled by the base course |
| GC-TEN | Tendon set — polymeric tendons threaded through the cell walls down the slope |
| GC-ANC | Anchor stakes and clips — J-pins, steel stakes and tendon clips |
