Hello! I have carried out a drainage with isodrän. On top of the isodrän plate and around the house, a plastic strip is placed and attached to the house's base. This is to prevent water from seeping in between the base and the plastic strip. The whole thing should last for fifty years and be buried underground.
My problem - I don’t know what type of sealing material to use between the base and the plastic strip, considering cold and moisture, etc.
Grateful for an answer!
Best regards/Gunnar
