my 5x5m cabin was erected on a 7x7m concrete slab 7 years ago(Ireland). Water is getting in from the bottom all around. The edges of floors are starting to rot and the wet is now seeping up the walls at all joins. How can I remedy this situation? Is it feasible to raise the cabin on car jacks or Should I cut the concrete close to the base. How can I repair the damage done. All suggestions appreciated. Thanks 🙂
