Bto owners. Can we replace drywall with concrete wall by ourselves

[matchy]

Do anything you want. Just don't get caught or kill anyone.

 

[FinchGuy]

Can put insulation in between.

Ya. Drill hole, spray in

 

[xllms]

Just curious...

loading definitely allow use of brick or hollow block walls. No issue at all.

as a general rule of thumb for layman, non structural elements can be removed.
For experts, some structural elements can be tweaked/adjusted if you know what you are doing. Of course HDB will think otherwise.
The higher the floor, loading required on the structural elements will be less. Hence if one check the structural loading calculations from structural engineers, one will find some columns on top 2 floors can be smaller or removed.

My friend's 6yo BTO already using drywall

Cannot drill and mount things on it

can, just need to plan in advanced and add bracing within the partition wall.

Aiya just check your floorplan la. The darker and bold colour is structured wall la. And others might be drywall.

The drywall does not give good protection against noise. But it's not so easy to kick la. More likely it will break your leg than you break the wall.

 

[ballastic90]

Don't think so

 

[xllms]

Cannot. The building design cannot take the weight. These days, even condo also use drywall.

don't anyway say cannot. HDB renovation is controlled at 1.2-1.5kN/sqm (cannot remember liao). Normal public buildings are usually done at 2.5kN/sqm (if my memory serves me well). At 1.2-1.5kN/sqm more than enough to use hollow block walls at strategic places add cement to support wall installation eg. TV. My agaration is probably use brick walls may not be an issue as well. Reno experts can prove me wrong since me no expert.
Even partition wall can install wall mount TV. Just apply 2 layers of 18mm chipboard (wardrobe material) and support 75" TV liao.

Dry wall can add insulation materials within to prove sound insulation. Of course interfacing detailings and workmanship have to be done appropriate to ensure minimum to no weak points for leakage.

mine reasle is concrete wall but still can hear upstairs party and sometimes when people talks can hear muffles sounds

 

[itangg12]

it ok lah now those new condor also dry wall, parc clementi, normanton pk

 

[keenklee]

Never hear of anyone’s flat have soggy walls. Mold yes especially toilet areas.

IMHO.
You see those HDB flats that the exterior the paint colour like different. Those are likely to be soggy walls.
So the consideration is not for new HDB is whether having wall mounted furniture is a good thing.

Actually only the top floor beams are thicker. Rest of the floors are same due to precast walls and modules.

The drywall that HDB used is rated for minimum 25kg load at each anchor point. With sufficient anchor point , you can mount most stuffs.

I personally havent seen soggy wall. What are the issues of soggy wall? I would imagine any structural impact from soggy wall is covered by building warranty.

KNN pay so much still use drywall.

Can. Have to use drywall anchors.

I suspect for those units at my block that have special paint outside, maybe water seepage.

 

[KnyghtRyder]

You sure the floor can take the additional load?

 

[KnyghtRyder]

What is the difference between dry wall and concrete walls ?

One is a wall.. the other like cardboard partition.

 

[1l92041H]

how to soundproof the stupid hdb drywalls?

 

[KnyghtRyder]

Should be ok. Just need PE approval for hacking usually.

u got check the cost.

Drywall need to hack?
Just cut and remove.
No hacking needed.
