Installing a driveway can be an exciting period for many households. One aspect that should be considered when choosing the surface is how will your driveway affect your local environment. The most direct effect is always the amount of runoff water from surfaces that are impermeable. Installations of tarmac and concrete driveways are the major culprits for this.
As urban areas in the UK have become more built up to cater for everyday city life, the amount of permeable materials has reduced considerably, increasing the over reliance on drainage being sufficient to cope with heavy rainfall. What we have seen is the rate of flooding increasing as the draining systems struggle to cope with the amount of water that is required to be drained over extended periods of heavy rainfall.
Households could play their part in helping to reduce this effect by installing driveways that are permeable, which means there is less run off water that has to go through the drainage system. Materials such as block paving, gravel and permeable concrete are the best to combat this.
