If your tiles or granite have been laid correctly, using a solid bedding of tile glue and screed underneath there will be no damage to your tiles. Problems usually occur when the tiler applies four or five “blobs” of tile glue to the underside of the tile and does not cover the full area of the tile. This is usually done to save on the tile glue but will cause a host of other problems. You will find you will have hollow spots on your tiles and in time the tiles will tend to crack and break. If the tiler has fitted your tiles in this manner, there is a chance that Steel Studio’s installers may break a few tiles, however, if the tiles are laid properly this will not be the case. Steel Studio makes use of the best possible machinery and equipment. You will find that our core drilling machines and rigs, are all the top of the range Swiss made Hilti machines. Our Hilti core drilling machines come standard with a vacuum based stand, with a sponge type base to protect tiles from been scratched. The core barrels we use are also Hilti barrels which have diamond tips to ensure a quality cut through the tiles. All of our installers have undergone strenuous training from Hilti themselves to ensure they are qualified operators. When core drilling, it is critical that the operators set the water switches correctly to allow the correct amount of water flow depending on what they are drilling through, such as granite or tile. Too much water or too little water will have disastrous effects and if the operator of these highly sophisticated machines is not qualified and competent, damage will be caused. At Steel Studio we believe that by using the best technology in the market and with the correct operator training, you will receive a world class product with no damage to your tiles or granite. Rather than worrying about Steel Studio damaging your tiles, make sure your tiler had laid your tiles correctly with proper bedding underneath and no hollow spots.
