Need advice regarding spalling concrete

[Jpquek]

Hi bros forumers,

 

Need some advice regarding spalling concrete and paint flaking in my kitchen. Have engage the town council maintenance people to take a look and was told that my neighbour on top had a leaking water pipe.....which causes all this spalling concrete and paint flaking......and was told that i need to pay 50% of the total bill to repair this. But the thing is that even my kitchen cabinet was damaged by this incident and also there are mould which are growing at the false ceiling in my living room.....now at the loss on what to do ....any advices would be appreciated....

 

Thanks in advance

its 50% bill on u n 50% bill on ur neighbour for the repair, me kena b4, i m the top unit n the unit below complain

 

even though its not affecting me

 

i think for your furniture u gotta engage a seperate carpenter to see if its repairable like changing the formica

dont think can claim this one

 

for the leakage repair costs

if u go see ur mp n tell them u cant afford, they MIGHT split it in some way. this is wad my mum did.

 

 

anyway i can dig up my contractor contact if u want

The steel bars used to reinforce the concrete do rust/corrodes while exposed to air/water vapour. The concrete it reinforce is slightly porous. Over time, the steel bars rust and expand, cracking the very concrete it is suppose to reinforce (the reinforcement can not be sustained/no-sustainable). During the British time, (more than a hundred years ago, they never used concrete pre-mixed at the batching plant and delivered to site) spalling concrete was never heard of. The batching plants need to add additives to the concrete for delivery without the concrete setting during the delivery trip (additives called retardant among suspected culprits for promoting steel bars corrossion). Some people thought hiding the issue behind thicker layer of concrete will do. Today, both public and private projects using steel reinforced concrete share the same issue. I am wondering if we, the consumers are all ignorant laymen/laywomen, of simply laymen/laywomen. The 'professionals' create problems to make themselves look indispensable at our cost/risks. To the 60%+, do wake up.

Solution: All steel bars must be sealed from corrosion be suitable sealant(s), not hide behind concrete, to create spalling concrete..

The rebar already weaken by the moisture, and rusted and thus exerting a pressure causing the concrete to crack.

Rebar weaken is danger for structural strength.

Patch up is just visual repair.

 

Will the floor last another 10years?

The correct solution is first to solve the water leakage problem then after that repair the spalling. to repair spalling all the defective concrete need to remove. the rust must be removed from the corroded rebar and the rebar treated with anti corrosion paint. the whole area then got to be restored by pressure grouting. as for the water leakage, if your cabinet is damaged, it must be quite serious already and should need an engineer to have a look

Patch up = repeat th same problem? Better to leave rebar xposed. Then coat with sealant like enamel paint (more effective measure, can last twice as long).

Once the problem started, all are temporary measures only. Anyone can be spectator, no need for engineer. A more durable repair is to re-construct the slab/beam where the spalling concrete is found. f cabinet is damaged, replacement cabinet to be ordered.

Obviously you are not one. if you reconstruct the slab and beam you still need an engineer else it is considered illegal or unauthorised work.

This is where the irony gets repeated.Iit is the engineer's defective design, and only legal or authorised work if repeated I meant the engineer will tell yu to repeat his defective design (so he get more futre businesses).

Anyone has any contractor to recommend for repair of spalling concrete at HDB toilet ceiling? Thanks.

[Holdenutessv]

50/50.

Same problem as well, water leaking from upstairs to my toilet n kitchen. Called up HDB then they contacted the contractor who was responsible for the renovation upstairs. Months pass, still no news from them to fix the problem when they promised they will...

 

Doubt can claim on furniture...

Why go town council? I called HDB and the problem solved in less than a month. Paid 25% of the cost. But the painting of the ceiling by HDB contractor is a very thin layer of paint which will start peeling after a year or so.
