The installation site at Whitburn had a small footprint due to minimal verge space; numerous utilities were found subsequent to topographical and penetrated radar surveys. An uneven bedrock was identified, indicating different levels of installation would be required. However, this was an obstacle Hydrorock was able to easily overcome due to the flexibility of the system whilst meeting the design brief in terms of sustainability, efficiency in water management and ease of installation.
Unlike traditional soakaway methods and plastic crates, Aquifer Blocks provide a more sustainable approach to drainage systems being constructed of stone wool. Whilst their capillary action reduces hydrostatic pressure on the base resulting in a larger infiltration surface area. The modular system permits almost infinite configurations permitting flexible installation solutions within the confines of each site.
Super gullies were installed to rapidly clear the surface water from the road, through a filter towards the Hydrorock system for buffering and infiltration. The beauty of this project is that these works were undertaken on the side of the road, equalling minimal disruption to traffic and reducing road closures.
Lee Sergeant from South Tyneside Council explains “The thing that surprised me was how quickly it went into the ground.” Continuing to say, “I’m impressed with Hydrorock and I’m very impressed with how easy it was to construct in the ground.”
There are clear advantages to the Hydrorock system in all factors. If you have a surface water management project where a more adaptable design could help overcome site constraints, please contact us.
