Anyways :
You can find geotextile there : http://www.premierlininginterplas.com/

Here is a price example :

two rolls (800 sq. meters). Cost of two rolls and delivery to KK site from BKK: 24,500 baht for two rolls, delivery to KK 1,000 baht, 7/1/09

So delivery might be a bit more to your place, but that's the idea.

I assure you I'm not gay, but I would kiss you for this post!
Thank you.
I wrote right away to request quotes on geotextile, liner and a membrane I dreamed about for my biodigesters.

you can make the pool in concrete then line it with epoxy resin, something the pool guys do

quite expensive but very effective

a cheaper method would be to lay wet sand as a base and line this with heavyweight polythene- stick the edges of each roll to stop leaks to make a large liner

more wet samd on top to protect it, then rocks or pebbles or whatever

this method may not be 100% waterproof unless you do it perfectly, but probably good enough

Yes, I wonder why it's so important to be 100% waterproof. There will be a need for more replacement water, but this is not a problem in my situation, there's lots of water available. Would this water risks destabilizing the base of the pond?
It's solid rock under more than one half of the surface.
For the last few days, I became convinced that the white rock wall was a mistake. There should have been a liner put there before the building. At the time I did not have a liner, and I thought I could use epoxy on the whole thing. Went to Global today, medai, no have epoxy, except for small cans of 2 part putty!
Then I thought I would cover the wall with the liner, with an underlayer of geotextile and get a third row of white rocks on top of the liner. But like you said "probably good enough".
Workers are back, preparin to mix and pour the ground lever concrete floor. More pictures tomorrow.

Have you got any photos of examples of what your doing ? Would like to see.

I looked up my book the other day and it is not a book on eco pools entirely, it just has 3 or 4 eco pools in it.

The folks at Premier have not answered me yet. I'm going to call them. I had 2 water tanks built behind the house four years ago, they rendered them with pure cement. One of them is dry, the other one 'humid'. This can be done, like you said, Paul. I will still use a liner for the filter zone with plants. For the swimming part, I like the idea of a tiled pool. I'm thinking of putting the liner inside the concrete, I mean one layer of concrete on the bottom and sides, liner, concrete with steel and tiles.. The liner would be continuous all the way, including over the actual wall, after enclosed in cement... A loss of energy and time. And a row of white rocks on top of the liner. The whole thing stays under water...

With pleasure, Nawty, what exactly would you like to see?

Had an interview today with a local roof contractor. The first. He insisted I use wood for the whole thing. I started considering the idea, but I did not feel he could do my roof the way I want it. All his examples are pretty straightforward, and straight! I want a rounded shape! He claimed he could do it, maepalai...
Back to the drawing board. I keep searching. I think it should be metal, and I was seduced by Dr Andy 's roof he built in Chiang Mai, I like those tiles. Now I need a bit of luck, find the right team.

Anything good and relative.....I am easy to please.


What is the idea of the liner if you are building the swimming bit just like a noral pool....but under water level ?

Here is a picture of the water tanks behind the house. 4 years, rendered with pure cement, pretty watertight, one on the right 100%, the other 98%...

As for the wall, it is just used to separate the regeneration zone from the swimming zone, so that plants and substrate stay away from the swimming pool. Water flows freely above the wall.

Thursday, 22 April, Ground floor concrete pouring, all should be done in one day!
Home made chute, ready to go at 8:30.


The steel reinforcement, the level markers, the side forms.

We will pour this section alone another day, it will need a stronger base, there will be a round tank with 40 000 litres of water.

So, 6 Lisus on top for cement mixinq and one Thaiai on the mixer, 4 more thaiais downstairs. I figure it's a bit slow, we'll add overtime at the end of the day.

At 10:00, all stop, syndical break! Normal, I go back to the house. At 10:30, everybody is sitting down! No more water. The pump quitted.
Coitus interruptus.

Sorry, I made a mistake and repeated the image!

We sent the Lisus to carrying compost, another job... In fact, the wire to the pump was a very small one, big enough for one reading lamp:-).
After lunch, like we say in Quebec, "on s'essuie et on recommence!" We dry ourselves, and we start over!

free publicity, thanks

and yes, the tiles look good and will weather well

the effect of the diamond/triangle is nicer than the normal square look too

they come in three sizes

Not surprisingly, at five o'clock, it's not finished!

So OT is called, Over Time, with a bonus of 80 tb and a meal!

At sunset, it already looks good, the middle passage is shiny like a mirror.

The cement is thin for the last part, there was a bit too much land fill...
The mixing crew leaves at 7:30, and my two masters in concrete keep on shining the hardening cement, after having sprinkled a mixture of cement powder and fine sand over the still humid surface. I stay with them and a shared small bottle of rhum, at the rythm of music from a phone. The atmosphere is peaceful, it reminded me of "corvees" we had in my home, where all friends shared a hard day of work for one of us, shared a meal and some drinks while finishing the job. Often, we ended up in a crazy jam session, found memories of a wonderful period.
I wish the same to all young life starters who decide to build their own house.

Friday morning, this looks good, the job was well done, with a little light from 3 bulbs!

The base for the water tank is planned and the digging starts, a drain must be put at the bottom. A group of Lisus are digging a new septic tank, better placed, the first one was filled uo earlier.

Yes I know it's confusing! It's just that I'm confused
At the planning stage, I study my options. This potential liner, when I have the cost from Premier, and have this compared with others, like Firestones', is only one option, and a new one, I was afraid that I would have to buy a whole roll, with plenty, enough to put it sandwiched between two layers of cement. Thinking about it now, I see that's overkill.
But to answer your question, I read so many things about this that I got less and less sure about making this watertight. And this thing about cement giving out phosphorus, an algae promoter...
Your good question, and the rain we had today, which showed me that the second floor was watertight, without rendering! These clarified my confusion...
I will keep getting info, but I'm inclined to do all in cement, probably cheaper. The waterproofing should lower the contact between water and cement.
I see this tread as a moment of confusion. It must be the moon

Is that forever, or just when the cement is new?

If you do it just in cement, you can add waterprofing compound to the cement; that would help keep it watertight enough for your purposes, as long as the cement is properly poured

The recommandation I found was to fill up, let stand for 3 weeks, then empty. Do this 3-4 times, then OK. I will do that. When I'm gone, mid june, I will request that it be emptied as soon as algae appears.
For waterproofing, I remember my first house, I had built a tank inside to raise trouts. I had found asphalt emulsion, 2 45 gallons drums, and this had replaced the water in the cement mix. This worked very well, never leaked. This emulsion is used industrially to stabilize soil before asphalting a road. I remember it was cheap, because I was very broke at the time. I wonder if this could be found in Thailand. They're building lots of roads around here.

Safety, anyone? Only one worker wears a hard hat. In Global, I bought 5-6 hard hat, as a gift. It was cheap, 49 tb, but my wife kept protesting that I was spending money for nothing! I gave the hat to the workers, insisting that the white one was for the boss... They were never worn! They stay there!

Footing for the round fish tank. This will be interesting. I found a factory in Chiang Mai that can bend metal sheets. They made 4 pieces, 4 m diameter. I will use this to build the koi tank.
