Keyblok Marker Block

With multiple applications, concrete marker blocks are a vital part of the Marshalls Keyblok range.

These 100 x 200mm blocks are available in a useful range of colours, perfect for delineation between parking bays and road lanes, as well as for permanent signage. Specially designed, these clear markings remove the need for overpainting and can effectively highlight specific areas for disabled parking, loading bays, electric car recharge points and other uses.

Available in both 60 and 80mm thicknesses, the blocks are slip-resistant and durable, with the colourtop range particularly suitable for highways and high traffic volume areas. Black and yellow or black and white blocks are often interspersed for effect such as at crossings.

The white reflective option is applicable for permanent traffic calming solutions – for example on roundabout chevrons. A coated layer of glass beads gives these blocks their reflective nature and ensures essential visibility.

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.
