<p>The system consists of cutting small pieces from the face of a tile and making holes through the tile and in the wall. Plugs of a non-degradable material are inserted between the tile and wall round an inclined tube used as a guide for a fixing dowel, e.g. of carbon or glass fibre, and filled with a sealing compound. After fixing, the small pieces of tile are replaced in its face to conceal the dowel ends.</p> |
