    Foundations - so confused

    Folks, can someone please, please help me. I'm designing a small, two story, house in BangSaray, about 7 km from the sea. What type of foundation do I need?. I intend to use lightweight roofing such as Onduline and 200mm QCon for the walls. I've been told everything from 8 metre deep pilings for every 3 metres of wall to a single 500mm concrete slab to 1m deep foundation walls. So effing confused.

    I self built

    There are many factors to consider

    Local geology

    Loadings

    Will your walls be for example

    Wooden

    Concrete slab/pour

    Q-Con aka Superbloc

    Aerated bolk

    Small Thai red Brick etc


    Welcome to pm

    If it is to be a main residence or you may wish to re-sell/insure it is worth spending the very little extra

    I used 5 tons of steel in total, my wife and local amateur builders considered mad

    When the earthquake happened , local temple collapsed my home didn't

    A competent engineer may well exist in local highway / land Office and it's amazing how cheap professionals can be.....

    pm if you wish.

    I used no wood in the external build for aesthetic and pest control reasons, I chose steel glass and 20cm thick Superblock and worth every penny.
    The extra cost per sqeare meter negligible when build speed relevant on 232sq m
    I chose Mae Makkan for fixtures harder than teak and seems insect proof after a decade
    I used to have a job at a calendar factory.
    I got the sack because
    I took a couple of days off.

    Hi and welcome... I did piling because... the OrBorTor engineer, who obviously knows a thing or two about the location advised me to do so. As has already been mentioned, it just depends what your soils are like... in my case there was a soft, springy 'upper' layer, but down below was a solid layer, and that's what we built off, hence the piles.

    Mine is also 2 story which also has an effect on the bearing (weight pressing down) of the building on the soils. Maybe a small single story home might be OK where a 2 storey would not.

    If you do pile, once the piles are in, in any case, you are still affixing the pile caps (same as your average spot foundation), then rigging a plinth beam around it all, and casting the plinth, again in the same way as if you had not done piles. Think of the pile as a foundation 'extension' to get your build on solid ground. (lol.. 'cos that's exactly what they are!)

    The OrborTor office is a good source of information and you will need them 'on board ' as ultimately they will be approving plans (unless of course you live in an area where 'approvals ' are 'not necessary'!!)

    All sound advice, just as I built on my 2 strey home.

    Orbor Tor also a good tip, need not be from local Office , I'd go by recommendation, ask around

    Every amphur should have geological maps for their area, go see your local or bor tor/town engineer and they would be able to tell you what you need. It's no good asking on the forums as different areas can and will be completely different geologically, so unless they live right next door, and have exactly the same sort of house, all these forum 'experts' are guessing. And that also applies to all the family experts as well ...unless they are qualified engineers ignore what B.i.L. Somchai says.

    The best, go around and see what the other do and make your own reasonable decision. Will you build a high rise tower?

    Clearly, despite the advice from members, he was so 'confused' by foundations that he decided not to go ahead?

    Still just that 1 post from over a year ago....

    Always remember there are two foundations...the overt group of mathematicians trying to accurately predict the future and the covert group using their mental powers trying to help mankind despite themselves.

    Sometimes Thais just totally confuse me on that lack of training given to staff.

    I asked a large company (Not CPAC who are very professional) for a price on 65 cube for a road of 280 KSC ready mixed concrete

    I get a phone call and some lady asked me and I kid you not....."can you tell me what this product is?"

    I said "WHAT!!!!!!!!!!!!!!!!!!!!!" you don't know what concrete is? said something in Thai and hung up on me LOL

    Obviously if you don't know then you don't have/need planning permission so I would side with Klondyke and ask a neighbor

    As for RM Concrete if it help you I found Siam City Concrete to be 220 baht per cube cheaper than the others I contacted

    I am confused ,Perhaps English is not your first language, .
    I don't see any samples.
    I dont even know if the above reply is a response to my reply.
    If it is , it is no excuse for being rude, the person at the other side of the telephone is not lust a voice , it is a person same as you, with dreams , aspirations, self respect, self esteem,a family etc.
    that person did not understand what you wanted and made the effort to call you back and try to understand. instead you insulted her. How would you like it if she was your daughter, wife or mother? How do you think she feels about farangs now? What do you think her demeanor would be when I walk in there to do business?
    Did she talk to you in English, or Thai. If in English, Perhaps her English was not good, if in Thai I am sure your Thaims not great.
    The simple response IMO should had being,tell her the name of the company that made your product, the particulars, and what you needed it for. I am sure she would had told you that they did not carried that product ,that's why she was not familiar with it , but had a similar product with a equal PSI .
    You would had got what you wanted, she would had got what she wanted, A Win, Win, situation.
    End of Story.
    The sooner you fall behind, the more time you have to catch up.

    No excuse for being rude is that why you insinuated I was a wanker? Now you are trying to tell me how to run a business I have been involved in for 21 years..and defend someone when you know nothing of the details.......are you a sweetie wife with nothing better to do with your time or what?

    Not that I should explain myself to you for being such a rude twat but I will

    After the first couple of attempts getting nowhere I sent her the URL for the product of their own website https://www.onestockhome.com/en/prod...mixed-concrete a map of the site location twice and she sent me two of these and asked me which one I wanted https://www.onestockhome.com/en/prod...ving-block_scg

    So I have since sent the whole thing again in Thai and guess what..........still no answer.


    Funny I found a few companies now who quoted without any hassle but you made your mind up I was the idiot without knowing the facts.


    Kinda makes you look stupid IMO
