    Advice Needed On Compacting Dirt.

    The missus just bought a two rai piece next to our (her) property where she now wants the house to sit. That's cool but I had already shifted a couple hundred 10 lor truckloads of dirt onto the other section and it's settled over the past three years. Ready to build on I think.

    My question is, what kind of earth-compacting equipment should I expect to find or what's available like in rural Suphanburi? I've got to get some more dirt in there and get it compacted.

    Thanks...

    Water lorry and a grader is enough, maybe a roller, they have roads there so must have graders etc, best if you could let it sit for a couple of years though.

    Also, a comapactor can help, but maybe not enough.

    It's also called a "whacker."


    It's like a mini-lawn mower and compacts the ground.

    Graders, roller, and compactors....bringing back the memories.


    Is just just dirt able to be compacted enought to build upon?

    Cheers DD & MM
    Looks like it maybe a couple years at this rate until I build the house.
    I'm sure I'll have to sink pilings even tho I'll be letting the dirt settle and will use a roller/grader/whacker before laying the slab.

    What's fill dirt going for down in Jomtien/Chonburi area, DD?
    Not the nice stuff - 'din dum' but the other that's used before topsoil is laid down?

    Cheers...

    I too am curious about this practice of raising the level of the building block. We plan on getting started on the new house next year. The (Thai) wife says we need to raise our 400 sq meter block of land by a meter to match the neighbours. OK, makes sense, even though we are on high ground, being the lowest spot around our plot could fill up like a small lake in heavy rain.

    She says we then have to leave the dirt settle for a year before we build. OK, make sense again.

    But then I see that the normal practice is to dig down through the new fill and put the foundations for the supporting posts into the now buried, previously existing original ground level. Thats OK too as labour is cheap and only a bit more concrete.

    But what really puzzles me is what I see in a lot of construction pics where they put more lose dirt fill in to support the floor slab. I would have thought this would lead to the slab cracking as the dirt underneath settles? Or do they use a mechanical compacter to ram it down? In Australia we use bedding sand under the slab.

    I wouldn't fancy doing 2 rai with one of them.

    Yeah wrong piece of kit for an area that size ! is used more often for back filling trenches and whacking down paviours on driveways that sort of thing .

    2 rai and you would have the permanent shakes for a month !

    Nor I.

    Just received a reply to the same question I posed over in CTH (coolthaihouse) forum and a guy in Phanat Nikhom, Chonburi says good clean red dirt goes for 650 baht for the large truckload and 450 baht for the small truckload. It seems it's coming from < 2km away so that must affect the price.

    Worked on a few of these things. They're alright for small stuff like a sidewalk where the depth of compaction is not too deep, but not for a build lot. I have seen "sheep's foot" rollers in use on some projects here, not sure of availability in your parts, the depth of the fill would dictate the weight of equipment and methods needed. Dumping dirt moving it around then waiting for time & weather to compact it is poor practice, although quite common here.
    Dump, grade, pack with sheep's foot, dump more grade & pack again finish with a smooth roller, is the best way. You can build right away. The equipment comes in varying sizes. The vibrating rollers are best both smooth and sheep's foot types.

    There's a company near my place that has all the requisite equipment in their yard. Being in Chiangmai I doubt hiring them would be cost effective. if you look around I'd imagine there were companies within 50-100k that could be hired.

    if the size of the lot was smaller The little Bobcats can have small rollers attached. It would work for a lot that size where the depth of fill is less than say 40cm or so, just take some time.

    Cheers Frankie - aside from DD's suggestion of the water truck which I know is available, not sure on whether a 'sheep's foot' can be had for rent in Samchuk. Probably in Ampur Suphan but I've got to do some homework on this. Thanks again for the ideas.

    Price comes down to the area of Thailand you are in, here in Pattaya it's 1,000baht for a 10 wheel lorry load.
