Geocomposites are prefabricated drainage products which

directly replace conventional granular fill. They normally consist

of at least two different components; a three dimensional

polymer core, which acts as the transport medium, and a geotextile

filter fabric which allows liquids to pass into the core but prevents

the surrounding fill from washing in and clogging the core.

Geocomposites need to meet the following criteria

a vital requirement.

Geocomposites applied to slopes and loaded with fill material,

are subjected to in-plane shear forces; therefore the method

of bonding the core to the geotextiles is also an importantconsideration. All Terram Geocomposites are thermally bonded

to ensure the best join between the constituent materials

and to minimise shear failure.

Terram Geocomposites offer solutions in both landfill capping

and landfill lining applications, effectively replacing traditional

stone drainage layers.

Geocomposites can be used in either application and offer both

Terram Geocomposites installed over contaminated soils and

below clean fill, form a capillary break preventing contaminated

water rising to the clean soils; they also form a horizontal

fabric to the specific application means Terram Geocomposites

offer the perfect blend of drainage capacity and protection.

Quick, easy to handle, efficient and cost effective drainage

systems are necessary in areas of construction such as basements,

culverts, car parks, reservoirs and many other structural andsubsurface applications.

Slopes and Embankments

The drainage function in stabilised earth embankments is

as important as the reinforcement design; drainage at the

toe and crest as well as behind the structure is an important

consideration. Terram offer a range of products suitable for

reinforcement that work effectively with Terram Geocomposites

in the drainage application to offer a total solution for

slope stabilisation.

Retaining Structures

To maintain the stability of a retaining structure it is

important to provide an efficient drainage system behind it.

Terram Geocomposites reduce pore water pressures. This enables

threatening saturated ground conditions to be avoided. Simple

and fast to install, this system cuts the cost of conventional

drainage systems and gives superior performance.

Buried Structures

Terram Geocomposites installed against the external faces of

a buried structure will form a highly effective drainage system

for groundwater. They replace traditional free draining stone

backfills and allow excavated materials to be used as backfill

thus offering savings in terms of materials both imported and

exported from site.

The Terram Geocomposite intercepts groundwater seepage

between the rock face and the concrete tunnel lining which

is then transported away in a perforated drainage pipe.

Geocomposite drains are used extensively in a number of

applications within highway projects. They offer significant

savings to the contractor in terms of both cost and time.

Geocomposite drains directly replace traditional stone drainage

designs; these are increasingly expensive and cause damage to

the environment, as stone has to be quarried and transported to

site. The excavated materials are often carried from site, normally

to landfill; using space saving geocomposite drains means these

arisings can be used for backfill, offering further savings.

order to maintain the desired moisture content within the base

and sub-base layers.

The use of the geocomposite fin drain system in this application

provides a fast installation and saves on excavation and backfill.
