Highways

Terram standard, non-woven geotextiles have been used for over 40 years in the construction of highways, car parks, haul roads, access roads, hardstandings, container port terminals and other loaded areas. These filter/separators maintain the integrity of the sub-base by preventing movement of subgrade particles into the sub-base.

Railways

The Terram PW range of geosynthetics provides the Permanent Way Engineer with established solutions for extending track life by preventing ballast contamination. Whether it's a simple filter/separator (PW1), a filter/separator with a more robust performance (PW2) or a filter/grid reinforcement composite (PW4-LA) for track construction over weak ground.

Landfill

Terram robust RG geotextiles provide protection to containment geomembranes by preventing their puncture by adjacent stone.
The choice of protector grade will rely on the type of stone that is likely to be used e.g. its size and angularity, and the depth of waste which will be bearing down on the geomembrane via the stone.

Ground & Grass Reinforcement

Plastic pavers and mesh products are ideal for constructing stable, natural-looking areas for vehicular and pedestrian traffic. These products ensure that soft grassed areas remain healthy and are able to recover from damage to the crown. Alternatively, the products can be used with gravels to provide a hard landscaped effect.

Foundation, Retaining Structures

Terram geocells are panels of interconnected, permeable cells which can be filled with site-won materials or imported fills to 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 have been used in major pipeline projects where they can be used to replace the thick sand collar that would traditionally have acted as a cushion to a steel pipe's coating. The mesh prevents stone in the backfill from abrading and puncturing the pipe's coating which would interrupt the cathodic protection system.

Coastal & Waterways

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

The growing need for geosynthetics

Within the construction and landscaping sector the use of geotextiles has become fundamental in solving an increasingly diverse range of global geotechnical and environmental problems.

Terram is a market leader in the design and manufacturer of innovative geosynthetics including geocomposites, geotextiles and geocells. Through a programme of continuous product development, Terram provides a unique range of value-engineered solutions that also help minimise the environmental impact of construction.
