We had the pleasure of welcoming Marshalls into our hub in Hebden Bridge this week, we have a lovely new display for you to see which demonstrates simple examples of sustainable drainage systems that we can adopt in our homes and businesses.
One side of the display houses a block of permeable paving called Priora, it looks like normal paving but it has larger gaps so the water falls between the gaps into a specially prepared sub base, the sub base holds the water allowing it drain slowly at a controlled rate which ultimately helps to prevent flooding.
The other side of the display shows a Drivegrid, a plastic honeycombed cell that is filled with gravel, it works in the same way as the Priora paving, allowing the water to soak into the ground where it can drain slowly away.
Both methods mimic natural drainage processes by holding water where it falls, stopping water from rushing off surfaces at high speed.
Marshalls are supporting Watermark by donating £1 from every sq metre of permeable paving sold in the Calder Valley.
Pop down and see this educational display at the hub in Hebden Bridge until the end of November.
