RC Walls
RC Walls
(OP)
An architect would like to put his radon barrier (DPM) through my RC wall. THey will seal around the bars with a bithutene.
I have not seen this before, but he said it is common.
IS he correct, the wall is all vertical no wind or moment loadings.
His argument is that it should be treated as a block wall ! I understand this but am concerned at interupting the bond of the concrete.
Any advice out there..
Thanks

The wall is load bearing with precast floor slabs on the next two levels.
My prefered detail is for the radon barrier (DPM) to dress down the internal face of the wall.
This would cost more due to the increased labour and materials.
I made the argument that we would lose a bond in the concrete but he argued that they do it in blockwork and precast concrete buildings?

it is not an opening, it is a damp proof membrane that runs under the floor slab and the architects wants to terminate it out side the building, it would be about 1.5mm thick so it will act as slip plane alone the full lenght of the wall

If you have an effective lapped and jointed DPM beneath the floor slab, why would you require an additional barrier within the wall construction?

Ask him this:
1. what is going to keep your wall from walking off when you back fill?
2. how are you going to apply your rebar from the slab/footing into the wall without putting holes in the barrier in the first place? What's the point?
3. And if it's done all the time ask him where? Prove it.
Good luck
