Concrete driveways, Resin driveways and suds compliance
Are you Suds compliant? Are Resin driveways? Do you know what it means?
The following is an extract from a contractor who was discussing permeable paving on a forum
“I have installed 3 permeable paving jobs in last 5 years. One was for an Eco Development, the other two were on large flat courtyard / parking areas that had buildings on 3 sides.
On the above projects permeable block paving was justified and worked great.
However, installing permeable paving on normal domestic drives is total nonsense.
What is the point in spending an extra 25-35% for permeable paving when the water all goes to the same place. Let me explain – Traditional block paving – we install Aco Channels at bottom of driveway or at the lowest point, which are connected into a soakaway, with an overflow into surface water drains if the ground is not ideal for soakaways.. Permeable paving – water drains through the blocks and sub stone, drains to the lowest point and then into a soakaway.
How can anyone justify the extra spend when it does the same thing – if you comply with the regs.
Someone has installed a permeable drive locally. Its 2.5m wide by 6m long – single car driveway. Drive slopes from garage to the road by about 2m, there are walls on both sides of the driveway. There is nowhere for a soakaway, unless you are going to pump water up 2m in height. Where is the water going from the permeable drive? Its going to collect under the paving at the lowest point and drain slowly onto the highway.
I agree with Tony, that all commercial projects should be Permeable, where possible.
How many supermarket car parks have you been in where there are hundreds of puddles – either badly laid tar or drains cannot cope.”
The important thing with drainage and permeability is that it needs to be correct for the application. With Resin driveways as they are not porous, assessment needs to be made prior to any type of driveway resurfacing – that not only means Resin driveways but block paving, slabs tarmac and concrete. That does not mean that it has to be permeable paving. If a new hard surface is installed there are various factors to consider – the type of soil for instance can have a vast effect on surface water. Will it drain to your garden or to the main drain system?
