MG15 Grid

A special grade of GeoGrid that has been developed with the UK’s market-leading grid supplier, Marshalls MG15 Grid provides additional stability within the sub-base of a Priora permeable pavement.

Installed directly over the sub-grade, the profile of the ribs and the shape of the apertures has been specially developed to maximise interlock with Marshalls’ angular Priora aggregate, confining movement and improving the CBR of the ground by 1%.

This can drive cost from the system, or in situations where excavation depth is an issue (such as city centres), it could make a permeable system a possibility where it wasn't before.

For more installation information, see the specification page or speak to our design team.

  • Ideal size and shape to interlock with Priora aggregate
  • Can improve CBR by 1% to save cost
  • Can aid installation of permeable systems where excavation depth is an issue
  • Roll size provides coverage of 200m2

Ethical Risk Index

This Radar diagram illustrates the level of ethical risk associated with a specific stone. Ethical risk is plotted against the 10 ten measures of the ERI, with each value drawn from reports produced by independent ethical auditors, engaged by Marshalls to provide non-biased and honest reporting into levels of risk in that supply chain.

Each of the 10 measure is designed to recognise different and discrete sources of ethical risk. This produces a bespoke, fit for purpose framework designed specifically for the requirements of the stone industry. The radar diagram itself also compares the Marshalls supply chain to the wider industry in that stone, giving users a working comparison of Marshalls supply chain to the industry average, in the opinion of the auditor.
