Geogrids: Installation

Geogrids

Where structural loads are anticipated or underlying soil is particularly soft, geogrid can be applied in conjunction with geotextile. Geogrid is a rigid geosynthetic material that can be laid on sub-grade to reinforce softer soils and provide a more even distribution of loads across the sub-grade materials.

  Geogrid Mirafi RS380i rolled out on subgrade surface.

• 

  Geogrid rolled out prior to installation.

• 

  Geogrid wrapped around Silva Cell® units to provide structural reinforcement along the walls of the LID feature.

Filter fabric that is installed to separate dissimilar soils and provide runoff filtration and contaminant removal benefits while maintaining a suitable rate of flow; may be used to prevent fine-textured soil from entering a coarse granular bed, or to prevent coarse granular from being compressed into underlying finer-textured soils.

Low Impact Development. A stormwater management strategy that seeks to mitigate the impacts of increased urban runoff and stormwater pollution by managing it as close to its source as possible. It comprises a set of site design approaches and small scale stormwater management practices that promote the use of natural systems for infiltration and evapotranspiration, and rainwater harvesting.
