Hi All,
I'm hoping someone can help me with a problem I'm having overlapping a new piece of DPM with an existing one.
The concrete slab shown in the photo's had sunk due to settlement of its deep (90 to 100cm) reject stone foundation. The area of slab and foundation from where the photo's have been taken has been removed and a new foundation put in place. The stones below the exposed visible slab have been consolidated by injecting pure cement/water mix, from the bottom of the stones up to the top, to form 7 or eight mini-piles (just visible capped with yellow sand/cement mix).
I can push the new DPM underneath or above the existing to give an overlap of about 60 to 70 cm and spread it out from side to side without too much difficulty. What I can't do is get it to slip up the sides of the existing slab.
Do I need to get the new DPM up the sides of the existing slab, if so, how do I it? I've considered cutting the existing slab along the dotted line shown in the last photo and then do the same for the other side.
Kind regards.
