Building Material

We're in the middle of building a new house. Before we started, I did a bit of reading on how to make buildings earthquake-resistent and I talked about the matter with the architect. Together we decided what to implement and what not. Many ways of strengthening your building have a trade off and some are aesthetically undesirable. Some can be costly too. The missus thinks it's unnecessary and a waste of money. We had a RS6.7 earthquake a couple of days ago not far away from where we live now. So I think it's a good thing to invest in.
What are you going to build, Anfooshi?
I am wanting to build a house, but based on my experience of renting homes here and visiting new home sites I think building a home can be a better option.

I do agree earthquake resistance should be considered, but a proper foundation is the key. I am not sure if they incorporate a Geotechnical engineer when building homes here. It's very important to know the type of soil in order to choose the correct foundation or the house will not resist the natural processes let alone a tremor.

I don't think a geotechnical engineer will be nesessary when building a one or two story house. An architect should be able to classify the type of soil you want to build on, maybe do a little bit of digging and then calculate what is required to make the building meet the minimum standards (SNI). From there it's up to you if you want to add more strength to the whole construction by enlarging the footplates and the foundation, or beefing up the columns, beams, larger rebars, make some changes in the design etc.
It's a bit like an insurance; it will cost you money while you won't see much of it nor will you enjoy it much. Until you need it.
 
Another place to find local available construction materials is from: tokopedia.

At this website, you can find all type of screws, nails, roofing, windows, paint, sealants, tape, fishers, ladders, hand and power tools, etc. However, don't expect great customer service and detailed specifications.

Since the covid-19, I have been shopping and buying a lot of construction materials from the above site and avoid going out to buy the construction materials.
 
Another large DIY hardware store in Indonesia is Depobanguan. The website is below:


Unfortunately, limited specifications on building materials. There is one in Sepong.
BJ Home, Bangunan Jaya Serpong and Depo Bangunan are all in Serpong area.
 
I need to waterproof and replaster a bedroom wall internally as i cant get access to the external wall (house built with only a small gap to next door house - why is that common here?).

Any suggestions on waterproofing materials? thanks

Depends on the current state of the wall, the quality of the original plaster. If it's really bad, you may have to remove all of it (around the part affected) until you reach the bare bricks. Then replaster it properly.

You can use Aquaproof Pro inside. But always use a roller for smooth results. This would be my choice. But, make sure you clean right away when you drop this stuff on the floor or elsewhere.

Or SikaTop 107 Plus.

Or Aquaproof Aqua Proof Cat Anti Bocor. The latter would not be my choice, but a lot of 'tukang kerja' will use it.
 
Shoot for 5mm total of aquaproof type paint plus fiberglass mesh plus additional layers of aquaproof.

You can use quality ready mortar mix, i.e. Tiga Roda TR 20, and add acrylic additive, for example, MP40. The additive will waterproof the plaster. After that, finish with TR 30 plaster layer.
