got 5 pictures, probably load slow..

total is 14 step (maybe 13)
5th step from picture should be actually 8th-9th step.

if anyone here have the knowledge..


as above, is it dangerous ?
can it be fixed ? thanks ! smile.gif


October update:

*tried with filler from ace hardware..cracks will come back in time...(3-6 weeeks)
*tried cement patch, i sapu the whole area nearby the cracks...cracks come back too but in longer time..(2-3 months)



any contractor or tips to recommend ?even it will not collapse, i would like to fix it as it looks ugly, can be see directly at my living room.
and issit possible to change the stair rail if i want to ? if not probably i can opt to remake the whole staircase.

QUOTE

your stairs will not collapse easily. try seal it with some semen will do.

if its like 50mm+ u might need some advise from contractor.

try to seal with cement patch or filler bought from hardware shop alrdy. but cracks still come out few weeks later.
will try with cement, but that will make it become ugly..no choice..
btw, semen....=.=""""

pls take some photo and post it here, if those cracks only occur at surface (plaster cracks) then u can fix it use semen... laugh.gif  laugh.gif hack bigger area then redo the plastering with some fiber mesh.

if the cracks is structure cracks ( cracks on concrete) then u need someone to check on the stability.............. do u feel any vibration while walking on the stair, u may want to stand at the 5th step, ask your wife/son to jump on 7/8th step , if u can detect vibration then u better move out..until u verify the house structure is sound.........LOL tongue.gif  tongue.gif

wa so scary..omg


QUOTE(wschan @ Feb 2 2010, 09:18 PM)
the crack happens at the middle of the staircase (at the waist) is because of the bending moment n deflection behavior..meaning to say ur staircase is failed in term of structural...normal concrete crack is allowed to 0.3mm...
putting cement or paint is no help, the crack will become bigger in future...
*
so any idea to fix it ? cost ?

Hi, just to share my view...

Most likely the crack is structure crack, suspected due to under provide of steel reinforcement.

I suggest you to ask your neighbour if they have the same problem. If it happens to all unit at the same location. High percentage there are problem with the design and you should inform the developer for rectification/varification.

If you happen know someone who is engineer and if you manage to bought the structure plan of your unit, can ask them for help and give you their professional view.

Once the root cause identified. the rectification would be simple.
Hope it helps

it is second hand old house, so every house different..cos last time staircase is kayu with lubang lubang one..
if not enuff steel so must remake ? can fix ? remake will cost a lot of time and how i can go upstair.
checked last night, the crack was 1mm or less..

U have to check whether there's displacement on both sides of the crack. If there's displacement even for 1mm, the stairs is not stable and will collapse! if not, treat it like hairline crack. Since each time u walk on the stairs, there's going to be vibration, solid filler may not work for your case, as the line will reappear. U can try mixing silicone base filler with cement (or some flexible filler), and fill the gap accordingly, it will work.
*
already used it for about 1 year, will the displacement show up ? (if it is showing up)
will find the silicone base filler and try...thanks

QUOTE(khoodennis @ Oct 27 2010, 02:13 AM)
It all comes down to the word CASH...
Sorry for being direct. If U ask here no one have seen it. Want a real advice get pro's advice on site viewing. As for me, you're repairing your doubt more than the stairs.
If U used MRR2 when it's known of being cracked then U got the guts not to repair ur staircase

If U got de CASH then just take it as you're buying a sleeping pill to help U sleep better at night.
*
cash i have a lot, and i want to sleep real better without sleeping pill. sorry to being direct.
i just dont want ppl to dirty my house and move my furniture here and there if possible.
as for me, you are not helping but telling me you are clever with guts.

QUOTE(alex_cyw1985 @ Oct 27 2010, 11:38 AM)
agreed with khoodennis

you have been asking for opinion since february, but until now still not yet fix / get any contractor for quotation?
*
thanks bro, i had been looking for a real good one who can fix it permanently, not those who only talk bullshit.
if you renovated your house before, i'm sure you know that most of them talk and look so promising/reliable and it became totally different when the project/payment is almost complete.
my purpose is to hide/fix those cracks permanently, not only staircase but also wall.

if u have good/skillful contractor please share.
