Bassosa Posted June 1, 2019 Share Posted June 1, 2019 My electrician is running conduits through some brickwork, non load bearing, but is basically destroying the bricks, leaving large gaps. I think the bricks might be fragile and/or too thin. Has anyone seen this before? This annoys me because I chose a cavity wall because I'm worried about sound insulation. I feel this is not going to help much with preventing noise coming through the wall, especially considering the design has power points on each side of the cavity wall, opposing each other. Can this be fixed and if so how? I was thinking of having them remove the conduits and replace all damaged brickword with a solid brick, then run the conduits down again.

sirineou Posted June 1, 2019 Share Posted June 1, 2019 The picture does not look too bad to me. Once the conduit is installed the cuts will be filled with cement. Link to comment Share on other sites More sharing options...

sometimewoodworker Posted June 1, 2019 Share Posted June 1, 2019 It looks pretty standard for those kinds of brick, they are cheap and you can now see why. It's a bit late now but building with something better would have been a good idea. Link to comment Share on other sites More sharing options...
Odysseus123 Posted June 1, 2019 Share Posted June 1, 2019 Yes. The ancient Romans tried to tell them how to do it..but,of course,they were 'farangs" and knew nothing. Try to think of your shoddy and illogical brick work as a lesson in ancient cultural anthropology. Link to comment Share on other sites More sharing options...
ballpoint Posted June 1, 2019 Share Posted June 1, 2019 The bricks also appear to have been laid on their sides, rather than face down. This will use fewer bricks, but makes the wall a lot thinner. Link to comment Share on other sites More sharing options...
Bassosa Posted June 1, 2019 Author Share Posted June 1, 2019 Thanks everyone. Solid input. Yes, the bricks being laid flat would've been preferred. I see now ???? This is how they fixed it btw. It's not a load bearing wall and they'll smear a ton of plaster on it but can't help feeling we're not getting the most out of the wall this way.

eyecatcher Posted June 1, 2019 Share Posted June 1, 2019 Too late now but next time You have paid 50x3bt for 1m2 of commons only 50mm thick. 75mm qcons will cost 170bt 1m2 75mm diamond is 136bt 1m2 100mm qcons maybe 200bt 1m2 Its a no brainer, I am convinced they use bricks and piles of sand and cement to overcharge customers and pan the labour out for twice as long.

bwpage3 Posted June 1, 2019 Share Posted June 1, 2019 That wall has no strength whatsoever. The mortar is all porous and was not mixed correctly. Link to comment Share on other sites More sharing options...
wisperone Posted June 1, 2019 Share Posted June 1, 2019 You gotta be f'n kidding. You will actually pay someone for that piece of work? Have them tear it down and do it right. The answer that they will smear it with plaster ...to cover up that crap is not good. One more case where they get away with substandard work because people are afraid to stand up to them and make them make it right. Link to comment Share on other sites More sharing options...

grollies Posted June 1, 2019 Share Posted June 1, 2019 Never mind the brickwork, I'd be more concerned about the wiring. Looks like blue and black wires, don't look to be big enough and where is the green earth wire as you have metal back boxes. Please put me right if I'm misinterpreting your photos, not hard to tell.

KittenKong Posted June 2, 2019 Share Posted June 2, 2019 That red brick wall isn't really a wall at all: it is a skin over the real wall behind it. As such having a load of patched-up holes in it isn't going to make it any less strong. But the real problem is the sound insulation aspect. For sound insulation you need to decouple the two walls, and ideally have some sort of resilient membrane between the two. Those red bricks seem to be touching the wall behind and so aren't going to help much for sound insulation. As the wall isnt finished you still have time to stick drywall onto the inner surface using green glue https://www.greengluecompany.com/, or use a mass-loaded vinyl membrane. https://acousticalsolutions.com/mass-loaded-vinyl-and-the-correct-uses-for-it/ In Thailand drywall/plasterboard with a bonded layer of polystyrene would be cheaper and much easier to find, though it works better for thermal insulation than for sound insulation. All will do more for sound insulation that that red brick skin, depending on the sort of noise you are attempting to reduce. Best option is to use resilient channels and install an extra stud wall. Good luck finding a Thai builder who has the faintest idea what any of the above are for. Link to comment Share on other sites More sharing options...
canopy Posted June 2, 2019 Share Posted June 2, 2019 That is surely the weakest constructed wall I have ever seen. I've always said god forbid the day they make a 1 inch thick block because everyone here will build their walls with it. And run chases in it too and your builder proves this. It should be noted even with AAC that blocks 100mm thick or less must not be chased yet everyone in Thailand buys the very thinnest 75mm blocks and merrily chase away in them. I am sure there are reasons for such guidelines and the owner will find out what these are sooner or later. Link to comment Share on other sites More sharing options...

We chased the AAC in our home 10 years ago and no evidence that being a problem. ?? Link to comment Share on other sites More sharing options...

Rimmer Posted June 2, 2019 Share Posted June 2, 2019 That has to be the worst cheapest pile of rubble I have ever seen. Get them to tear it down and put up double Q Con blocks if you want soundproofing. Galvanized steel conduit is usually only used on surface installations where it might suffer mechanical damage, maybe in this case it doubles as rebar to help strengthen the wall Link to comment Share on other sites More sharing options...
