French drain/ decking??

no keep drain in place if its working water will still go underneath decking boards

Hi Kirsteen In response to your question,yes.The ground level should be no higher than 150mm below the damp course ( two bricks ).This is standard practise. Many thanks James Fencescapes

Hi, removing of the soil/dirt at least 2 bricks below the damp course is a positive step in the right direction and then reinstate the french drain as an extra precaution. the drain may in fact be working but the damp may be also be that the original damp course has broken down and needs replacing. It is bad practice to have any soil or dirt near the wall as it acts like a sponge so remove it any way it can only help, then fit the decking and enjoy the summer as its on its way. regards rob

Hi Kirsteen, i am currently building a large rear garden decking for a customer who had the same problem as yours........i basicaly reduced the ground level 150mm below the dpc level of the house and installed a french drain running along the rear of the house.......the decking will come right up against the house so they are able to open the rear doors and step out directly onto the decking.......its the only correct way to do it.
