Highways

For over 40 years Terram standard, non-woven geotextile filter/separators have been used to maintain the integrity of the sub-base by preventing movement of subgrade particles into the sub-base.

Applications have included construction of highways, car parks, haul roads, access roads, hardstandings, container port terminals and other loaded areas.

Railways

Terram Permanent Way (PW) geosynthetics provide the Engineer with tried and tested solutions for extending track life by preventing ballast contamination.

The range includes filter/separators (PW1), filter/separators with a more robust performance (PW2) and filter/grid reinforcement composites (PW4-LA) for track construction over weak ground.

Landfill

Terram Robust Geotextiles (RG) range gives protection to containment geomembranes by preventing puncture by adjacent stone.

The grade specified will depend upon the size and angularity of stone used and the depth of waste bearing down on the geomembrane via the stone.

Ground & Grass Reinforcement

Terram Grass and Ground Reinforcement products create stable, natural-looking grass and gravel areas for vehicular and pedestrian traffic. They ensure soft grassed areas remain healthy and able to recover from damage to the crown and create desirable hard landscaped effects.

Foundation & Retaining Structures

Terram geocells are interconnecting, permeable cells which, when filled with site-won materials or imported fills, form ground stabilisation platforms and gravity retaining structures. They also provide a terraced facing for reinforced soil structures which provides an environmental-friendly appearance.

Pipelines / Utilities

Flexible Mesh products applied in major pipeline projects replace the thick sand collar that would traditionally have been required as a cushion to a steel pipe's coating. The mesh prevents stone in the backfill from abrading and puncturing the pipe coating which would otherwise interrupt the cathodic protection system.

Pipelines / Utilities

Coastal & Waterways

Terram Robust Geotextiles (RG) are thick, robust filters used below rock armour and pre-cast concrete revetment systems to ensure underlying soils are not leached out by tidal action and are far simpler to install than the traditional layers of graded stone.

The Increasing Need for Geosynthetics

Terram is an innovator and market leader in the design and manufacturer of geosynthetics. Through a continuous programme of product development, Terram provides a unique range of value-engineered geotextile, geocomposite  and geocellular solutions that help minimise the environmental impact of construction.

The use of geosynthetics within the construction and landscaping sectors has become fundamental in solving an increasingly diverse range of global geotechnical and environmental issues.
