During the electrical upgrade, several PEHD tubes were laid through a hole in the wall (60cm thick). I am not sure how to fill the hole - want to keep the water and the dirt outside. Insulation is not a requirement, since it is in the basement (c.a. 70-80cm under ground level). I currently do not think that the wall outside will get insulated. It is currently in a dry area, i hope it stays dry, but want to keep it watertight as much as possible.
I was recommended to use well foam to fill the hole. I am rather inclined to use the foam from the inside, and from the ouside use something fluidic, that sets and hardens (e.g. some kind of asphalt/bitumen?). I also want to have it rodent-proof/insect-proof. How to fill the hole?
