Erosion Control


TERRAM Geocell 25/10, 25/15, 35/10, 35/15 & 22/20

TERRAM Geocell is a relatively shallow cellular confinement system, used to combat erosion on slopes up to 45 degrees. 

The geocell is fabricated using TERRAM permeable geotextiles, allowing water to flow freely between cells, encouraging drainage and promoting vegetation growth and is flexible enough to be formed around trees and other obstacles.

TERRAM Geocells are supplied as compact man-handleable panels ready to be expanded on site to 5m x 7m or 6m x 3m areas. Once expanded the honeycomb of diamond-shaped cells measure 100mm, 150mm or 200mm deep depending on the item specified.

The expanded panels should be fixed at every perimeter cell and at 1m centres throughout using steel fixing pins. Once secured on the slope, the geocell can be filled with soil or a mineral fill. The confined fill is able to better resist the erosive effects of wind and run-off. 

Seeded topsoil is the most suitable fill for less-exposed slopes, with small shrubs offering improved protection, whilst a granular material offers the highest protection.

The Terram geocell confinement system is suitable for:

• Cut or fill embankments
• Dams or spillways
• Revetments
• Abutment protection
• Geomembrane protection
• Soil-nailing cove
• Landfill capping
