HDPE Geocells
NEW robust 3D cellular confinement system designed to improve soil stabilisation, control erosion, and increase load support.
Overview
Terram HDPE Geocells are our latest robust 3D cellular confinement system designed to improve soil stabilisation, erosion control, and increase load support.
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.
Product Benefits
Soil stabilisation, erosion control and load support
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 subbase materials.
Sustainable solution
HDPE Geocells can help reduce the CO2 footprint of a project by limiting the transportation of imported infill and 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.

Frequently Asked Questions
What is Terram HDPE Geocell?
Terram has developed HDPE (High-Density Polyethylene) geocells in addition to their permeable nonwoven geotextile geocells. HDPE geocells are another type of geosynthetic product used for soil stabilization and erosion control.
Terram HDPE geocells consist of a series of interconnected cells or chambers made from high-density polyethylene. These cells are typically filled with soil, aggregate, or other fill materials to create a stable and reinforced structure. The HDPE material used in Terram geocells provides strength, durability, and resistance to various environmental condition. The HDPE geocells are designed to contain and confine the fill materials within the cells, preventing soil erosion and promoting load distribution. They are commonly used in applications such as road and railway construction, slope protection, retaining walls, and load support.
What grade of Terram HDPE Geocell do I need on a slope?
Generally, for slopes up to 30 degrees, grades TG356, TG445, TG 356. For slopes between 30 and 45 degrees, grades TG356, TG445. Please see the Terram Geocell erosion control SDI (specification, design, and installation) guide for more details.
