|Construction in Thailand Is building in Thailand as bad as it seems? Can properties really be built and fitted out to European standards? Would you like to Build your own house in Phuket, or a swimming pool in Bangkok? Solar water heating in Pattaya? Or maybe you want to build a resort or guesthouse on Koh Samui? If you want to build a luxury house in Thailand then this is the forum for you.|

I have seen many videos about house construction in Thailand. I have never seen one where the build includes a damp course.
Is this a standard technique in Thailand or is it largely ignored because of the habit of building a house on compacted soil which is raised, please ?

I also have wondered about the lack of a damp proof course in the construction of Thai houses concrete framed houses, and it's long term effects.
From my own observations of my in-laws house with no damp course, you will have about 40 years before it starts to cause serious structural problems.
To try and stop the rising damp, my in laws had the floor and walls (upto 1/2 metre) of there semi detached row house tiled about ten years ago, all this did was allow the damp to travel further and faster up the walls and concrete columns, this has now had the effect of causing concrete rendering to spall off the walls above the tiles, and even some of the concrete columns are now showing the early signs of concrete cancer due to the rising damp corroding the re-bar. Interestingly the damage caused on the party wall is much more noticeable than on the other walls.
This is one of the major concerns I would have about the traditional Thai house building process, and would be also be interested to know how this could be avoided.

I think every house build will be different as to what approach you take to ensure you don't get damp?
We have never had a problem (4 houses) current house is about half metre raised above ground level (the reinforced concrete), the house level was originally raised about 2 meters, we used a very rocky soil that drains quickly, we are also on a slight hill which obviously helps.
If you were to build in very wet soil conditions it would be preferable to raise the house so you have no ground contact apart from footings?

I guess a visit to Thai Watsadu etc. would tell if they have any manufactured rolls for such a purpose.
If not, then it is not normal practice.
But you could use any heavy duty plastic sheeting between the footings/foundations and the walls and a gob of silicon around the rebar?
No one on TD is gay. If suspect, it was probably because of the way they were reared.
I apologize if any offence was caused. unless it was intended.
You people, you think I know feck nothing; I tell you: I know feck all
How much more grievous are the consequences of anger than the causes of it.

No damp course here. Floor is 80cm above ground. Well ventilated crawl space below concrete floor. I have wood floors so used a vapor barrier between concrete and wood. Comes in big rolls. Bought at Global House. No problem with moisture wicking up through concrete.

Thai rarely think beyond their next meal, so a 40 year lifespan for a house, well .............
Not many young farang building houses either, so in current practice, the house will likely outlive you.
See Norton's post above for palliative care.

Once you demolish such a wall you will experence the huge effort to break it.
That's why we never see any problem with the Damp Course, do we?
Wondering, how it is in the areas with houses standing for long months under flood water 1m high.
