Geocells are permeable 3 dimensional cellular confinement systems that provide civil engineering and landscaping solutions for erosion control, slope engineering, load platforms and tree root protection.


Slope erosion control
The use of Terram Geocell for erosion control applications eliminates complicated and expensive construction techniques. Terram Geocells 3D structure provides a blanket of 'cells' on the slope surface which can be in-filled with a variety of materials depending on the application; either topsoil, aggregates, from sands and gravels to larger stones and cobbles. This improves resistance to erosive forces such as rainwater run-off on steep or unstable slopes, or slopes exposed to severe hydraulic or mechanical stresses.


Typical applications:

• Cut or fill embankments

• Dams or spillways

• Abutment protection

• Landfill lining, covers and drainage

• Steep slopes

• Soil nailing cover


Load Platforms
Terram Geocell’s  provide solutions to load support problems as it provides a permeable stable base for paved surfaces and surface stabilisation for unpaved areas. The cellular structure performs as a semi-rigid 'slab' when filled with stones or gravel, distributing loads laterally and stabilising the base materials. This helps to reduce sub-grade contact pressures and minimises surface rutting. Terram geocell also prevents the lateral displacement of infill and reduces vertical deflections even on low-strength sub grades.


Typical Applications:

• Stabilised drainage layer

• No dig tree root protection

• Permeable load supporting surfaces 

• Sub-base stabilisation for block paved areas

• Green access roads and temporary green occasional car parks

• Permanent and temporary access roads, footpaths and cycle paths.


Tree Root Protection
BS 5837: 2005 for trees in relation to construction and APN12

In recognition of the fact that trees are sensitive to disturbance the British Standards Institution has published recommendations on how to protect trees during development. In line with the earlier British Standard (BS 5837: 1991) the most recent guide, published in September 2005 (see further reading), recommends that there should be a 'root protection area' in which development should not be permitted.


In 2007 the Arboricultural Advisory and Information Service published Arboricultural Practice Note 12: Driveways Close to Trees (APN12) which suggested that driveways could be installed within the root protection area subject to roots and the soil not being damaged.


APN12 advised that driveways could be installed within the root protection zone provided that an above-ground, no-dig construction was used. This advice was incorporated into the recent British Standard which recommended that the most effective means of achieving this was through the use of a three-dimensional cellular confinement system, such as the Terram Geocell System.
