Hello,

we are currently building. Next to the residential house, there is a basement room that serves as the foundation for the garage above. The ceiling of the room (i.e., the floor of the garage) was cast with in-situ concrete C25/30.

We will build the garage itself at the earliest in one year, maybe only a carport. Until then, the concrete is exposed to the weather and has already been like that for 2 months. I have now been advised that this is not good and that I should apply a seal. UV-resistant pond liner was recommended.

Can someone here confirm this or suggest alternatives?

Hi,

I also sealed my terrace with pond liner. It works perfectly. It’s basically the same material (EPDM) that is used for flat roof waterproofing. It just doesn’t have official approval for that, but who cares if it’s only a temporary solution.

Just make sure that no water can run underneath. I put a slope insulation made of Styrofoam underneath for a few euros and screwed an aluminum strip to the wall connection to the house so that the liner stands up there and no water can get in.

It has been working perfectly for 2 years!

Regards, Tom

Pond liner is quite expensive and not drivable, right?

I just got a tip for silo foil. Does anyone happen to have experience with it?
