I was having problems with penetration in my basement. It consisted of salt crystals that damaged the plaster, and if sprayed for too long, moisture penetrated the wall. I contacted several companies for a filler. Except for Kemo, all of them were stripping the interior walls, applying a layer, and then applying a special finish (which can only be treated with vapor-permeable paint; wallpaper is out of the question). Only Kemo suggested they could solve the problem externally by injecting (drilling through the wall). Ultimately, they opted for this solution, knowing that other methods were always possible. However, the injection worked perfectly. No more damp walls, no more cold bridges caused by condensation. Simply done. And covering the drill holes (Kemo has already filled them, but they still need to smooth them out) took me a day. I wholeheartedly recommend this company. They are professional, work cleanly, and keep their promises.

After initially receiving sound and expert advice, we made quite a few mistakes during the execution of the work. Ultimately, we achieved a reasonable result, and now we can only hope that the moisture is truly gone.

They did not solve the problem as promised and sent an invoice that was double the agreed price.
