Hey guys! Does anyone have experience in fixing concrete cracks on the floor? It's indoor so I guess should be easier to DIY and fix it on our own?

I came across few products in Shopee and was wondering if anyone have used it personally, or should i hire a contractor to assist with these cracks..

Thanks alot guys!

Get specialist tu inspect before repairs. Need to remedy the source not the symptoms..

Can this fix the problems at J Satine ??

Thanks asdasd, yeahh looking for specialist now and they mentioned that need to fill in the holes and repaint the whole place

Not to sure brother because I am not in the construction line

Actually, floors are constructed with two layers. The concrete layer and then 2" thick of sand sreeding. Concrete layer is structural and usually we don't see it. Sand screeding is the smooth surface that we could see before tiling and timber floor. This layer covers the concrete layers.

Usually, it is the sand screeding layer that will have crack due to the mix ratio for the sand and cement or the preparation work. Usually, before sand screeding, the concrete layers must be clear of dusk and should be wet. If all these are not done properly, you could hear the empty sound.

So, my suggestion before repairing, buy one drum hammer and do the tapping test to see whether there are other areas that have so called "empty". Usually, this type of empty (i.e. the cement and sand are not bonding) will cause the tidy gaps, which eventually develop into cracks.

After identifying areas affected, then better get the contractor to quote.
