snowy 36, the problem is that the basement was not sealed at two floor-to-ceiling light shafts - it should have been torched twice. the problem is also that now no one can guarantee whether the renovation can be made 100% watertight. we are currently submitting the amendment plan - according to the building financing, the authority will approve it. once approved, the building financing must renovate. basically, it means digging up on two sides again and applying tar twice and torching. at the moment, they are willing to renovate. possibly some injection will be necessary. we hope the company agrees to the renovation concept. otherwise, we are stuck. renovation costs are enormous and we have to complete the building for move-in.
