We have a 12" drop from our patio doors & front door to an old concrete path.
I'd like to raise the path to the height of the doors so as you step out, there's no drop down, I'd create two steps further along the path to compensate for the height gain.
I'd like to build a small 12" high wall about 4' away from the house, backfill with rubble / MOT & then have a gravel / shingle finish on the top couple of inches. I may then add a deck the other side of the path, but that's an aside.
Is there an approved way of building this with regard to the finished path height being almost / equal to the DPC?
Cheers.
Ideally the DPC should be 150mm above the outside floor. This is to do with water splashing up the face of the wall and then breaching the DPC line.
It probably wont be an issue if you are looking at putting a gravel finish on it as the rain will just dissipate. I would however tank the outside of the wall with a tanking fluid, Thoroseal or Vandex to 150mm above the new path, make it a black stripe to not only prevent water ingress, but also to stop the dirty marks from the "splashback".
Thanks for your reply, it makes sense.
Ours is a 1960's bungalow with a lot of old concrete paths that surround the bungalow. One corner already has a sloping path within 1" of the DPC!!! I've already removed the north facing sides 6" of concrete that was up to the DPC & replaced with shingle to allow air movement.
Out of interest, what's the difference between water splashback hitting the exterior wall above the DPC & rain falling directly onto the wall above the DPC?

Doubly-soaked?
