Terram HDPE Geocells are a robust 3D cellular confinement system designed to improve soil stabilisation, erosion control, and increase load support.

Terram HDPE Geocell are APN 12 compliant by UK Arboricultural Associations for tree root protection.

Compared to traditional construction methods, Terram HDPE Geocells are a cost-effective and sustainable solution, enabling significant cost and CO2 emission savings, by reducing construction depth and granular infill importation by approximately 50%.

The robust design of HDPE geocells allows for fast installation, eliminating the potential for cracking and deformation of the structure, consequently reducing maintenance costs and ultimately extending the design’s life.

They can be used for multiple applications, including slope erosion control, construction platforms, road sub-base stabilisation and tree root protection.

Features

Terram HDPE Geocells are designed to provide a long service life.
They are manufactured from high-density polyethene (HDPE) and other special additives to sustain dynamic installation methods.
HDPE Geocells have been tested to offer >5000 hours of ESCR (ASTM D1693) and high UV resistance.

Geocells soil stabilisation, load support and erosion control properties make them suitable for multiple applications, including the below:

Slope erosion control
Load platforms and road sub-base stabilisation
Tree root protection

Benefits

Extended design life

Terram HDPE Geocells reduce the risk of structural failures, by improving soil stabilisation, load transfer, and erosion control. Geocells prevent platform settlement and deformation, and improve slopes resistance to erosive forces.

Cost-effective

HDPE Geocells support a rapid installation and allow you to half your spend on infill materials and reduce time and money spent on excavation works. They reduce the required construction and excavation depth by 50% vs. traditional construction methods, whilst enabling the use of available local infill, such as sand, removing the import cost of traditional pavement sub-base materials.

Sustainable solution

HDPE Geocells can help reduce the CO₂ footprint of a project by limiting the transportation of imported infill, the amount of infill required, and prolonging the design’s life.

Geocells also foster tree development and slope vegetation growth, which ultimately contributes to CO₂ capturing, by preventing soil and vegetation erosion on slopes, protecting tree roots from the damage and starvation caused by compacted topsoil.
