As this winter has demonstrated the increasing rainfall this country has been receiving has caused misery for thousands of people across many counties.
There are lots of things that planners need to do to get Britain ready for the ever increasing rainfall that weather forecasters have been predicting for some time. One of those is the introduction of more SUD schemes countrywide.
A SUD (Sustainable Urban Drainage) scheme consists of drainage systems designed to alleviate the affects of flooding. One of those systems is Permeable Paving.
SureSet UK Ltd is the UK’s leading manufacturer and installer of Resin Bound Permeable Paving, which if used in conjunction with a permeable sub-base build-up, allows water to infiltrate back through to the subgrade, avoiding the type of surface run off which can cause floods, especially in extreme events.
One of the main advantages of using Permeable Paving over other SUD approved methods, such as swales, and ponds etc is that it doesn’t take up any extra space, as we need the driveways and pavements anyway, which makes it dual purpose product.
One local authority planner from a densely built up area in London recently told me that he saw Permeable Paving as a major advantage over other methods, especially in heavily built up places such as London. His reasoning was that the other methods would take up a serious amount space, and that meant using up lots of expensive land. In his words “Permeable Paving killed two birds with one stone”.
When speaking to local authorities, the relative low maintenance of Resin Bound Permeable Paving is also a major advantage when compared to other SUD schemes. Their major worry is that once SUDs comes into legislation they will be forced to adopt these flood prevention systems, and with no extra funding for the maintenance of these systems expected to be forthcoming , something low maintenance like Resin Bound Permeable Paving is seen as a major plus.
Although Permeable Paving is not the only solution to controlling the affects of heavy rainfall, it is increasingly becoming many people’s answer. You can even combine it with other systems, or a variety of systems to suit any situation and location.
Where soil conditions do not permit infiltration (clay based soil etc) or infiltration is not desirable, installing Resin Bound Permeable Paving onto a granular sub-base, which is itself installed over an impermeable membrane, can allow the water to be channelled off in a particular direction to a containment area for a delayed discharge, or to a swale to convey the water away from the local area into the desired discharge area.
SUDs will eventually be law, and this winter has shown many people that there is an urgent need to tackle the problem of flooding head on, and Resin Bound Permeable Paving supplied by SureSet UK Ltd is one way this can help.
