Orton Rd Posted January 10, 2021 Share Posted January 10, 2021 Never used either but need to patch up some first class building work ???? done a few years back. Lot of deep uneven cracks, all needs ripping out and re done but Mrs against - too much dust! Soudal foam and others like it look easy to use but maybe not as good as the ads suggest?

Popular Post Backslider Posted January 10, 2021 Popular Post Share Posted January 10, 2021 crickey, i'm very much a DIY amateur, but it looks like the problem goes deeper than filling in a few cracks. for sure i'd start again, and make sure the foundation was solid. i'm sure experts here will give you more technical advice on what's necessary . 3 Link to comment Share on other sites More sharing options...

Don't worry about foam, just use some gaffer tape ???????? 2 Link to comment Share on other sites More sharing options...
liddelljohn Posted January 10, 2021 Share Posted January 10, 2021 Id be worried that looks like foundation settlement and water influx during rain under the building ,, really needs serious investigation ,, 2 Link to comment Share on other sites More sharing options...
HighPriority Posted January 10, 2021 Share Posted January 10, 2021 That’s two different locations ? slab is seriously defective. A floating floor of some sort is the only 1/2 feasible option if not pulling up and starting again. If you’re intent in NOT trashing it and starting again I’d rub a bit of sandpaper over the broken edge to remove the sharpness and fill with silicone (spray with soapy water/detergent and wipe to remove the excess silicone) 2 Link to comment Share on other sites More sharing options...

The extending part cracked away due to subsidence and a bit of help from poor construction. Never thought of silicone just garden underneath it. They did not use proper hardcore or any rebar to join up to the existing base. 1 Link to comment Share on other sites More sharing options...

It MIGHT just sit like that forever or keep opening and closing with the moisture levels in the ground. Demolition of tiles and the new slab, pin and pour new slab, let it cure for 6 weeks and retile is what I’d do @ my place... sorry for the bad news. 1 Link to comment Share on other sites More sharing options...

I wanted it done like most of the others not built up as we did but like this, though ours is a bit higher 1 Link to comment Share on other sites More sharing options...
HighPriority Posted January 10, 2021 Share Posted January 10, 2021 The intention of what they did was ok, sadly the execution sucked... steps are ok as such, but a level floor is superior imho. Link to comment Share on other sites More sharing options...
