Priora Permeable Flag Paving

Part of the UK’s best-selling permeable block paving range, Priora Flag Permeable paving offers creative freedom with 3 sizes which can be laid freely in single-size or multi-size random course patterns, making for modern designs and unique finishes.

The patented Marshalls Priora nib provides 40% more interlock than standad blocks, combining excellent infiltration rates with superior structural performance, meaning increased longevity and a reduced need for maintenance.

Priora Flag Permeable paving is the perfect option for pedestrianised areas, while expert engineering means it can withstand occasional heavy traffic and loads of up to 7.5 tonnes. Its complementary colour palette of Charcoal and Natural provides truly creative design options, as they can be mixed and matched to make unique designs and styles.

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.
