Gripsure donated some Gripsure Aquadeck® boards for a bridge for Ramsbury Primary School's Rain Garden which was designed by Wendy Allen Designs and funded by ARK Action for the River Kennet. The purpose of the new Rain Garden is to slow the flow of rainwater, improve stormwater infiltration, and reduce sediment runoff into the River Kennet.
A new downpipe from the school's roof is sealed at the base so that it fills with rainwater. Like a 'Torricelli tube', water then squirts out of three holes in different size arcs.
When full, this overflows to a second downpipe which turns a waterwheel feature and outflow into stormwater planters, made from galvanised cattle troughs.
The stormwater planters are filled with plants that can tolerate short periods of waterlogging as well as drought. Each stormwater planter slowly drains (or overflows) to an underground pipe leading to the Rain Garden.
Above the underground pipe, a dry chalk stream symbolises the River Kennet and features both chalk aggregate and hazel faggots / chestnut posts, traditionally used to extend or reinforce river banks.
The new bridge is made from green Gripsure Aquadeck®, an innovative non-slip decking board that is SuDS-compliant and allows rainwater to drain through the board back into the watercourse below. The vibrant non-slip rubber crumb infills are child-friendly and ensure students stay on their feet when crossing the bridge on rainy days.
The Rain Garden is situated 5m from the building at the lowest point of the garden and allows rainwater to slowly infiltrate into the soil.
