How to waterproof a house/patio wall?
We are currently working on a terrace (construction). The house is still standing. The floor slab was built on a layer of gravel, and the sides of the floor slab were properly insulated. Now we have chosen patio doors, which should provide a transition to the terrace at ground level. The terrace must also be built on a layer of gravel. This raises the question of what a reasonable waterproofing system should look like.
We apply a pitted membrane in front of the existing floor slab insulation to protect the insulation. In addition, we implement a slope of <5%). What else needs to be done besides this? The exterior plaster has not been applied yet. So we still have all the options.
Answer
I assume the following:
1.) half of the red Styrodur is applied over the plaster.
2.) Then a waterproofing solution is applied on top of the plaster
3.) At the place where the plaster will be laid, a roofing felt is applied to the masonry, which is cut off flush with the plaster from above.
4.) Where there is no paving or only earth/gravel, it is only backfilled.
