Jilly Posted October 29, 2021 Share Posted October 29, 2021 My new driveway has to be SuDS compliant and I have been given some nice grey pavers which would do the job, but I don't think they are permeable. They are to go on a Type 3 Mot sub base, and onto sand and my understanding is that if there are gaps for the water, it would be SuDs compliant. Is this correct and any suggestions as how best to do it please? Thank you Link to comment Share on other sites More sharing options...
nod Posted October 29, 2021 Share Posted October 29, 2021 If the joints are sanded rather than pointed Water will soak right through BC will be fine with that 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted October 29, 2021 Share Posted October 29, 2021 (edited) There are special pavers that are shaped to leave a 3mm gap between. The system requires special fines free sub base and pointing with a kind of grit. All very expensive. If your BC accepts normal kiln dried jointing sand then that will be good, although not permeable / SUDS compliant. https://www.marshalls.co.uk/commercial/permeable-paving-and-suds Edited October 29, 2021 by Mr Punter Link to Marshalls added 1 Link to comment Share on other sites More sharing options...
