Flood Prevention with Permeable Paving

Posted: Monday 26th November 2012

June and July saw large areas of the country experience record levels of rainfall, with a number of communities, such as Hebden Bridge in West Yorkshire and Croscombe in Somerset, suffering the devastating effects of flood.

Climate change experts suggest that these extreme weather incidents will become more commonplace, and it is now widely agreed that flood prevention solutions must be sought and implemented.

Permeable paving is proven to help prevent flooding as it is specially designed to allow rainfall to infiltrate naturally back into the ground, rather than driving increasing volumes of water runoff into already overburdened sewers.

Marshalls has been supplying their market leading Priora Permeable Paving system to for over a decade. Marshall Water Management expert, Chris Griffiths, said: “Climate change means that extreme weather conditions are happening more often, unfortunately there’s nothing we can do to stop it from raining, but we can control the surfaces that it lands on.

“This summer the people of Hebden Bridge and Croscombe experienced firsthand the devastating effects of heavy rainfall entering overburdened and antiquated drainage systems. The use of Priora Permeable Paving is a key strategy in minimising the effects of increasingly heavy rainfall and flash flooding.”

Chris concludes: “Many people wrongly believe that permeable paving is too expensive or difficult to install, this simply isn’t the case. The fully installed cost of a Marshalls Priora pavement is equal to, or even less than the cost of an equivalent Tarmac surface with sufficient channel drainage, and our Priora block is engineered to make installation simple.”

Mary Dhonau (OBE), Chair of the Flood Protection Association, said: “Extreme weather incidents are becoming the norm rather than the exception.

“We can’t stop it from raining, but we can plan for these events. Making permeable paving the first choice for any hard standing requirement is the very least local authorities, planners, architects and homeowners can do to help to alleviate this growing problem.”

Recently Mary Dhonau visited Hebden Bridge to see the aftermath of the floods for herself. To see the video about Mary’s visit, and to hear advice on how to minimise the risk of flooding, and also how to cope with the effects, please visit www.youtube.com/MarshallsGroup.
