Secure an island in the kitchen

[Arjay12345]

Hi am installing several units in the centre of my kitchen that will act as an island. The floor has been tiled. I have installed electric loose wire underfloor heating though not in the area under the island.

Any suggestions on how I should fix the units to stop them from moving around? I was going to screw some wood blocks into the floor which the units could sit around, but I'm afraid of cracking the tiles (just in case even though they're tough old tiles). Or I could screw in grout lines or corners

Is there are glue substance I could use?

Thanks

Use a tile drill to drill through the tiles

An ordinary masonary drill on the rotary setting will happily go through tiles, but remember to keep dipping in a pot of water to keep it cool; use a screw with a sharp tip, and knock it with a hammer to crack the glaze for the starter hole. You've obviously got standard plastic legs in the carcases, but if you try and fix these down, then any pressure on the units would snap the legs, so you need a bracing system that goes up in to the carcases. How many are there in the island configuration.
