Hello everyone,
We are building our single-family house through a general contractor. Today, I noticed that the perimeter insulation was damaged during the excavation work (see attachment 1). Is this a serious issue?
Additionally, a studded membrane layer was installed on top of the perimeter insulation. It was attached to the perimeter insulation at certain points. Is this correct? As a result, many stones fell between the perimeter insulation and the studded membrane during the excavation work. Is this a problem?
Thank you very much.

If there is a large stone in between and it presses into the insulation, the effectiveness is lost.
The correct approach would be to remove the dimpled membrane once and check, but probably no one will agree to that.But only in that one spot. That would be manageable. However, if there are several spots, damp areas could develop in the basement.gamer456 schrieb:

The consequence is that during excavation work, many stones fell between the perimeter insulation and the dimpled membrane. Is this a problem?I understood this to mean that stones fell in at several spots. The original poster might need to clarify whether the stones are only in one location or spread everywhere.

Also, there is direct damage to the dimple membrane and the insulation. Is that less serious than the stones?

Also, there are direct damages to the dimple membrane and the insulation. Is that not as serious as the stones? The dimple membrane is only a mechanical protection layer. If it has some minor damage in a few spots, it’s usually not a problem. As for the insulation, it depends on the size of the damage. If a fist-sized stone has pushed into it, I would consider replacing that section.
I would have addressed the excavator operator myself. You can easily cut off the last 5cm (2 inches) of soil by hand with a spade instead of experimenting with the excavator bucket in that area.
