Pocster Posted June 21, 2018 Share Posted June 21, 2018 Hey all I know you are meant to have the final floor level 150mm below DPC But my DPC ‘wall’ is just an external leaf tied to the timber frame . On that basis is it ‘less important ‘ to maintain that 150mm distance ? My issue is the front pavers will be just 20mm short of the entrance threshold to keep architect happy . But on the side - keeping pavers at the same level means maybe only 30mm below DPC. Block work as I have said is really just a weather screen .....

Mr Punter Posted June 21, 2018 Share Posted June 21, 2018 The 150 DPC rule is to help prevent the bottom of the wall becoming saturated from rain splashing up. If it is only a small section and it is not facing the prevailing wind you should be OK. Sometimes you can just have shingle up to the wall to reduce spashing 1 Link to comment Share on other sites More sharing options...
Onoff Posted June 21, 2018 Share Posted June 21, 2018 I was always told 6" (150mm) is the height an average raindrop bounces. It's why all our lead capped plinths for plant atop roofs are this high as a minimum. 1 Link to comment Share on other sites More sharing options...
