How to remove a concrete plinth in kitchen?

Anonymous user 16/03/2024 - 2.31 PM

We have removed an old oil Aga (oil disconnected) and we are left with a 100 x 67 x ?? cm concrete plinth that we need to get removed (and then levelled) to make way for a more modern range cooker that doesn't need the plinth. I tried to break this up using an SDS drill with masonry chisel but it just channelled 2 or 3 inches and the slab didn't break up at all - it also looks like the "slab" might be more than a slab as it seem to sit lower than the bottom of the adjacent wooden boards. The people who removed the Aga think it's block and beam flooring but I can't be sure (it's not solid concrete as it's above ground level but it's not springy either). Can anyone suggest the best way forward? It's very hard to get any local trades where I am (Dartmoor), but it's beyond my skill level! If I get the adjacent board removed to see what's there it might be clearer but I'm concerned it's a much larger slab of concrete - ultimately it needs to be removed but left strong enough for a 320kg range.

Are you a tradesperson and able to answer this question?

I would hire a larger kango from like your local tool hire store. Using a spade peice gradually chisel away at the edges until you go just below the floor level. Once all floor is level use screed to level the flooring out underneath them I would say get it tiled underneath just for the extra support

Clear the room and seal doorways up open window then I if it’s as hard as you say I would use my stilh saw with diamond blade in it and cut length ways down to the depth of the underside of the floorboards adjacent to it at 2 inch spacing then use a 9 inch angle grinder with diamond blade in and cut into the base of the plinth along its length until the first 2” strip cut free and continue until all strips are up. Also a heavy duty breaker will do it both noisy and dusty options but if You think you have a block and beam floor I’d steer clear of the heavy duty breaker as you could do more damage to the beams

Depending on the depth of the plinth to be reduced, i would strip cut into the top of the slab and break of the strips. This may seam like a long winded way of reducing the slab but it would make the breaking much easier and quicker in the long run. You can then reduce the slab to just below the kitchen floor and then use a self levelling product to leave the area smooth ready for the arguer. Then tile the plinth for a detailed, traditional finish if preferred. Hope this helps. Mark
