I posted here quite a while ago about the manky old concrete path in the front garden of my London terraced house ... finally got round to taking it up when, lo and behold, underneath is the original geometric tiled path (small, coloured tiles in a "Grafham" design). Over 90% of the tiles are fine, mostly still stuck down to the base, but the base/ foundation has cracked and shifted, so it's a case of re-laying the path on a new base.
This was confirmed by a pro company I asked to quote, who said it would be too labour intensive for them to salvage/reuse the tiles on my limited budget. So, in the spirit of UK d-i-y, I'm going to try to do it myself. I will need to remove the tiles, clean them and get some matching replacements, lay a new foundation, and re-lay the tiles. Any advice please on:
1) removing the old tiles which are still firmly stuck to the old concrete/mortar base layer ("gentle" use of hand-held cold-chisel?) 2) cleaning dirt and concrete residue from the top surfaces of the tiles? (Acid brick cleaner or a more "sophisticted" cleaner from someone like HG, followed by wet and dry abrasive? One old post here talked about using a carborundum stone and water) 3) removing big globs of concrete/mortar stuck to the bottoms of the tiles - i.e., can I chemically or otherwise break the bond between a tile and the old mortar it was bedded in, or somehow "shave off" most of the old mortar/cement? (Someone suggested to me using an electric tile cutting saw to get off most of this, but holding 2"x2" tiles vertically upright against a fast saw blade sounds rather unsafe) 4) do I need a DPM under the new concrete sub-base? 5) I also need a new York stone front gate step, which needs to have corners rounded at the front and also be notched to fit round the flanking brick pillars - is cutting this a d-i-y-able job, or should I make a template and pay a pro/supplier for a York stone cut to shape?Many thanks for any advice whatsoever.
