DPC against pavers

[Pocster]

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 .....

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

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.
