Terram HDPE Geocell 200/356 is a high-capacity cellular confinement system designed for heavy-duty ground stabilisation and structural load support. With a 200mm cell depth, this variant provides maximum confinement and enhanced performance in applications subject to sustained vehicle loading or weak subgrade conditions.

Manufactured from UV-stabilised high density polyethylene (HDPE), the expanded honeycomb structure confines aggregate or selected fill material, improving load transfer and reducing deformation under repeated traffic.

How It Works

When expanded and secured using steel Geocell U-Pins, the interconnected 200mm deep cells provide significant vertical and lateral confinement. This improves structural stability and reduces settlement across weaker ground conditions.

The perforated cell walls allow drainage and prevent water build-up within the structure, maintaining long-term performance.

Key Characteristics

• Cell depth: 200mm
• Designed for heavy load distribution
• Expanded panel size: approx. 2.5m x 6.5m
• Manufactured from UV-stabilised HDPE
• Perforated cell walls for drainage
• Provides enhanced structural reinforcement on weak subgrades

Installation Overview

Geocells are supplied collapsed and expanded on site before being anchored and infilled with suitable structural material. Pavement design should be based on anticipated traffic loading, soil classification and required design life.

For challenging ground conditions, separation or stabilisation layers such as Terram T1000 or Terram Bodgrid GC30 may be incorporated within the construction build-up.
