Hi. I am a first time self builder. Building an ICF house near Watford. Structure is up, roof is going on soon. Planning on putting thin coat K-Rend directly on to the ICF.

The builders that built the walls have put 110mm soil pipe through the walls before they poured the concrete. The plumber has come today to look and has had a wonky one because they used underground pipe that isn't UV stabilised and they say there will be a problem with fitting to the pipes after the rendering is done. If we take away the insulation then the pipe can be joined but then they said the krend can't be [patched to make it look good. So I have come here looking for suggestions. So far I have seen some collars that go on after is that the best bet?
