Hi all,

I have planned to extend my wet kitchen. The area to extend is 18' x 5'.
The problem i facing now is do i need piling or not for single story 18' x 5' area.

My neighbor is extending his wet kitchen also. His contractor told him that the soil in our housing area is soft. And need RC piling to do extension.
If not , the wall will crack since the house will sink for a period. He also claimed that even use kayu bakau also cannot stand for it.

But the problem now is another contractor that i meet up, he told me actually no need pilling, using large footer then already can extend the area.

One of my cousin also is working as contractor, but he is not working in KL area. He also claimed that have no need piling for just 18' x 5' area.
If i worry about the sink, use thicker steel + larger foot is good than enough for it.



So i hope you all can share your experience to me.

Thanks a lot for your advise. Appreciate all the comments.

Do you plan to extend the 1st floor in a later date ? If you do, then you will need piling.

Else, a 3' x 3' x 4'D footing will do with a cross foot beam.

I did not plan to do 1st floor. Just ground floor with roof. So Is it means no piling needed? Thanks.

theoretical answer is do a soil investigation...

Best is have piling.
But key issue is also do ur current house hv piling?

If house sink but ext no sink, ur house still will crack...
The effort to attach ur house base and ext also inportant...

I think should have since my house is DS. If need , does i need use RC piling? Since my area only 18 x 5.

Thanks

Don't think is necessary

Is your front and back have many heavy vehicles passing by or not? If YES and no pilling will have high risk of crack.

I think would not have many heavy vehicle passby. Since that is residential area.

Mine did not do piling, just stronger footing. Because I told my contractor i need a base allow me to have 2nd floor in future. Sometime is good to overdo a bit

In most ground floor extension, no need piling. Footing is sufficient

Do a on site Soil Investigation like Mac Probe, one point only cost you few hundred, but it would mean a lot to justify the bearing capacity of your ground....

If diff to arrange, check what's your existing house footing design, best is for you to follow back, so that your extension can have a similar settlement as your current house...

Cracks always occur when there's differential settlement...

If your house new or old? Isit still settling? If you install pile and your current house still settling down (which I'm not sure), then crack would likely occur also...

Regardless of soil condition, for single storey extension it's illogical (read MAD) to be founded other than RC footing.
Piling will not only damage yr existing house but neighbours' too.

Where to get ppl that can do soil investigation ?

My house is new. Not sure is it settling. But just hear contractor told me that my house area's soil is soft.
Need RC piling only can prevent crack. Even Kayu bakau also cant prevent the crack. And the crack will continue happen non stop if use kayu bakau.

Ya. I also told by other contractor that piling will damage neighbour house.
But using grill to piling that is ok.

My cousin told me that using bigger footing and thicker steel is more than enough for single storey extension.

Just that 2 contractor whose renovated a lot my house area claimed that only RC piling can do for extensions.

can tumpang ask? I'm also planning to do a 20 x 12 extension for kitchen... need piling ka?

my contractor told me he will hack the existing double storey wall, then sambung the new footing with the existing double storey footing so that it can be more tahan. Does it work that way? piling expensive la...

If is just ground floor extension no need piling

Then no need to do pilling.

I'm planning to do the same wet kitchen extension for almost the same size. How much does it costs you?

Same size with me ? 18 x 5 ? Contractor that quote me use RC piling is RM35,000 for single storey extend.
