Quick Building Question

[Freddy]

Guys, I'm laying some artificial grass and going to do the job myself.

Can anyone tell me the Thai name for Sharp Sand as opposed to building sand.

Also, can I get small chip stone here. I've had loads of the stone for mixing concrete but not sure if I can get small stone/chippings.

and if anyone close to Buriram, Lam Plait Mat has or knows where I can hire a a wackier for the day

Never seen 'sharp' (that is to say, crushed) sand here. I reckon you read somewhere that you need sharp sand to lay artificial grass. You  need a nicely levelled layer of sand, which admittedly is easier to do with sharp sand and which is in fact what I used to use back home for this kind of job). Underneath that it would be nice to have a good drainage to stop too much water collecting in the rainy season to stop it going squelch. That's why you are looking for a finer grade of broken stone than is generally available as the sand will be washed away into the gravel. If you are likely to have a drainage problem then maybe you might think about a thin layer of weak concrete as a base, 2% slope to one side. Then you won't need a wacker.
Geotextile, available at Rueangsangthai, would also prevent sand trickling down into the gravel if you use that instead of concrete.

Davureborn.......your correct, I was purely after the sharp sand as it compacts better but if not available then not a huge issue. And yes, the finer gravel is for drainage and also it compacts better than the larger stone. I am intending to purchase the geotectile from Mr Pichai to hold the sand and also as a wed guard. Maybe overkill but I'm considering 2 layers, one between the sand and stone and the other between the sand and grass backing just as additional assurance against weeds growing through. I've found a good supplier of the artificial grass in Bangkok , not cheap but product seems good, very realistic looking and considerably cheaper than the crap they've got in Home- Pro and the like. Currently doing the ground work and my back is killing me,

Hang on mate, you don't need to compact three centimetres of sand. Can't be done I would claim. Just water it in and relevel if necessary. Two layers of geotextile is definitely overkill, unless you plan on driving trucks over it.
