Used in the majority of building, civil and marine engineering projects with a vast range of applications the functions of geosynthetics are as follows:
| Seperation |
The use of geotextile to prevent the intermixing of dissimilar soil layers. |
| Filtration |
The use of a geotextile to allow water to pass through whilst preventing the uncontrolled passage of water particles. |
| Reinforcement |
The use of the tensile properties of a geosynthetic material to contain deformations in soil structures. |
| Drainage |
The use of a geosynthetic layer to collect and transport fluids within its thickness. |
| Protection |
The use of a geosynthetic material as a stress reduction layer to offer protection and reduce damage to an adjacent surface or layer. |
| Erosion Control |
The use of a geosynthetic material to help prevent the loss of soil particles from water erosion. |
Woven Geotextiles
|
Manufactured in a range of different polymers, weave patterns and strengths. Woven geotextiles provide a cost effective solution for the separation of granular fill materials and for the provision of sub structure support.
Most commonly used for the separation and reinforcement of soil and aggregate layers, applications include road, railways, foundations, embankments and coastal defences. |

Non – Woven Geotextiles
|
Designed and developed to offer optimum performance per unit weight. Their resulting mechanical robustness and excellent hydraulic properties make them the ideal choice for applications where separation and filtration and erosion control are required. Non- woven geotextiles, due to there high elongation at break , offer greater resistance to installation damage.
Ideal as a separating/strengthening layer under access roads and areas of hard standing, filter surround for trench drains, separation to stop the intermixing of dissimilar soil layers. |

Geogrids
|
Geogrids provide engineers with a cost - effective solution for sub-base reinforcement and soil stabilisation where soft and unstable soils are present . Geogrids can be employed in single or multilayers and a range of aperture sizes are available.Typically used as ground stabilization under roads, railways, ports and paved areas. |

|
Access Protection Systems
|
Designed to allow the development and extension of vehicular access areas. Used for gravel retention and grass protection. Quick and easy to install allowing developers to build new access areas which are both pleasing to the eye and consistent with the existing enviroment.
Used for caravan/camp sites, overspill car parks, public and private driveways, access routes. |

Bank Stabilization
|
Erosion control on banks and slopes is a common problem faced by many contractors and engineers. It can be addressed by the use of structural engineering or by the use of erosion control mesh/matting.
Mesh has a dense three-dimensional structure that is designed to become a permanent and integral part of the slopes/banks vegetative structure. Natural fibre matting can be used in environmentally sensitive areas, these natural fibre products will eventually biodegrade after the protective vegetative layer has been established. |
