Seal quarry stone walls / virgin stone walls yourself

After the injection PERMAGEL finds its way into every hollow spot of the wall. Every stone is reached, PERMAGEL seals up against moisture up to 100%. No need to dig up outer walls, everything can be done from the inside.

Exactly for this application PERMAGEL was developed by us and the Frauenhofer Institute (our Partner). PERMAGEL is a volume-filling gel which perfectly seals up every hollow spot, joint, etc. inside the masonry. No need to prepare the hollow spots with something like special mortar or filling the hollow spots with hygroscopic silicone microemulsions or similar.

After checking the basic structure of your building together, the level of dampness, and the way to proceed, we tell you where and how deep to drill and how much material you need.

Please use our expert advice via phone or e-mail. It’s free of charge.
