Driveways & Paving

Driveway above DPC

Anonymous user 3 March 2024 - 3.46 PM

We have just had a new driveway installed replacing our front garden. It has been paved quite high and at the highest slope is covering the DPC. Our builder claims that the 150mm is just guidance and as long as the water is running away from the house to drain naturally that is fine (slopes to aco drains right at the bottom of the slope and edge of the road). Please could you advise if the work is indeed acceptable and safe? If not, any advice on how best to resolve this in the most efficient manner would be greatly appreciated. Thank you in advance.

The 150mm rule is best practice and should not be breached unless absolutely necessary and agreed by the customer. however where it is necessary and in this case a concrete channel should be installed against the wall where the breech would occur conformant to regulation with a fall of minimum 1.40 leading to a drain or soakaway system. it is worth noting that if the regulation is breeched it may well be picked upon in any future conveyancing survey and may attract a valuation decrease or a provision for remedial work to be carried out.
