Of course in Thailand people do as please and they don't care about rules. But if one want to do AAC correctly, 100mm blocks or thinner must not be chased, ever. Now even if you do have 125mm (5-inch) blocks or thicker below are the rules from Hebel, the company that brought q-con to Thailand: "The depth of the chase must not exceed 25mm - The width of the chase must not exceed 25mm - The maximum number of chases allowed is 2 chases per 1 metre length of wall. - All chases must be backfilled with a material that will adhere to the wall". Also the minimum thickness required for exterior walls would astonish people and maybe even moreso the typical block thickness in many developed places is 37.5mm (15-inch thick walls). But in Thailand of course no one cares about durability, r-value, or noise abatement and just get the cheapest blocks they can find, call it a day, and get to that bottle of chang and life goes on. It's just a totally different approach to building. Link to comment Share on other sites More sharing options...

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 I have to agree. They could have at least laid the 'little itts' flat. Link to comment Share on other sites More sharing options...

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. Plaster....are you posh....?...???? Link to comment Share on other sites More sharing options...

shaurene Posted June 3, 2019 Share Posted June 3, 2019 They have been cut nice and tidy, you are lucky, looks like a decent Thai Electrician, most others would just hammer the spaces out. And those bricks are shit, all hollow and no real strength, cheep cheep. Would have been better and stronger with breez block. Looks good to me. Kep his phone number.

zyphodb Posted June 3, 2019 Share Posted June 3, 2019 Thai builders are great at building using bamboo & small trees, as far as using even semi modern materials go though, the vast majority of them haven't a clue and just make it up as they go along... This is probably one of the reasons, (as well as ghosts of course) why Thais don't like buying secondhand buildings Link to comment Share on other sites More sharing options...
rocketdave Posted June 3, 2019 Share Posted June 3, 2019 I've always been amused by Thai construction methods after I saw some 30 years ago a sea front bar being built with similar bricks but using sea water the mix the cement. I was an aerospace quality engineer prior to retirement but I know that you don't use salt laden sea water to make any lasting structure! Link to comment Share on other sites More sharing options...

This will use fewer bricks, but makes the wall a lot thinner. But it's worth checking that you didn't pay for the total number of bricks that should have been used the correct way, ie., laid flat. They have used less bricks this way - did they by any chance pocket the difference? Link to comment Share on other sites More sharing options...
eyecatcher Posted June 3, 2019 Share Posted June 3, 2019 Even the bagged cement here offers huge 15bt discounts. First time i was faced with a cement choice "well poon thammada is not strong, have not much portland cement" But it was 15bt a bag cheaper.....thats the key Link to comment Share on other sites More sharing options...

Pedrogaz Posted June 3, 2019 Share Posted June 3, 2019 Fore the electrician. Knock the wall down and start again but first do it with a large firm, someone you can sue and get a written contract. Pay what they ask but give little upfront. Any work they do that is shoddy, tell them to repeat it. It will be a headache for you, and especially for your wife who will have to tell them 'no money until it's done right' but it will be worth it.

I will never understand why red for live and grey for neutral wasn't the obvious choice the world over. As for green, don't you know you don't need that in Thailand? Not same America. ???? But seriously there should be an earth line. It is now PEA policy for connections to new buildings that an earth be installed. On existing buildings already on supply it is not in question. The brown and blue and yellow/green that are more than less the international standard was chosen to overcome the most common form of color blindness which in many instances prohibited sufferers from becoming trade electricians (or so I was once told ). My transition from red, black and green was to see brown as in the family of red, blue in the family of black and yellow green hybrid of green. lol Have never ever understood why black is used as the phase wire in single phase circuits!

Depending on the specs you are used to blue and back are standards for wiring in some countries and the conduit being metal acts as the earth so long as it is all joined back to the circuit breaker box and earthed there.

Like the overwhelming majority of walls in Thailand it is not load bearing. The posts and beams are the load bearing structures. It is just an infill wall. It seems that you don't understand Thai building systems at all. Correct, the (double) wall does nothing more than separate two rooms. Infill, not structural. However, soundproofing is important to me so have a meeting set with builder & electrician to address the fact that holes have been made in the brickwork. Btw, the brickwork has indeed been tied into the sides and there will be more reinforced concrete work on the top to "set" the top row of bricks. I will look at the electrical work closely to see if there's an earth wire. Thanks everyone for chiming in. Link to comment Share on other sites More sharing options...

Its not baseless mate , sooner or later it will start to shift and crack because of rain , soft ground , hard wind , so then the plasterwork will crack 100% . He says you won't see anything of the bad brick when it's plastered , thats treu . Untill your plasterwork starts to crack and that will be very soon after it's done you can count on that more then you can count on these unlisenced crap workers .

Bassosa Posted June 3, 2019 Author Share Posted June 3, 2019 I should also point out the my builder is going to use some sort of mesh, much like chicken mesh to cover the concrete in some areas, I believe around the power points, door frames etc Is this to prevent cracking?

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. And don't let any bad falangs graffiti on it. These are the worst building material you can buy here as far as I'm concerned, even the concrete blocks (5 baht) are pretty thin, the aerated ones are better but the "standard" size at 7.5cm is still way too thin, best lay them on their sides to get a decent thickness or buy the thicker ones.

Nah 20 parts sand to 1 part cement is "just fine", and don't forget to keep adding water as you go especially after the 1 hour lunch break, good as new.
