Definitely Not.
But thats what you get here for slab on ground the basic min standard
For polished concrete floors It would have to be upgraded..thicker slab and mesh, 2 layers of mesh, control joints ,etc

Re: polishing concrete - heaps of questions! 43Feb 28, 2015 9:19 am The issue we have with slab on ground is basically trying to determine what's happening under the ground (Stiffness, consolidation,shear,etc), but because the slab is on the ground then nobody really cares about strength,shrinkage, serviceability, ultimate cracking.Whats the worst that can happen..cracking->failure->collapse-> NO ( its not as if your ground slab failure is going to kill anyone). LOL I find clients are told to tolerate crackings in polished concrete but not in reinforced brickwork? So Say engineers gets paid $20/m2 to design (min cracking) while the polishers want $200 m2 and guarantees nothing? Go figure... IMO,the client's better off paying $220? When clients insist on no craking we (engineers) calculate (Simulate coupled physical) load effects on building elements , soil,slab,wall etc,etc. the results will dictate, amount, steel grade, locations, bar or mesh,etc, Clients should insist on the same service from the builders/contractors for polished Ground Floor slabs.... but they don't.my2c Designer,Engineer (Civil,Const & Envir),Builder,Concrete & Masonry Contract.Struct Repairs Re: polishing concrete - heaps of questions! 44Feb 28, 2015 11:44 am Umm why are you picking on 'following' trades? The engineer will be fully briefed, one would think of the vagaries of a specific building site. All things are considered by the builder, addendum's are signed off on by the engineer and by the floor finisher time, be it lino, tiles, timber or polished concrete, that the engineer did make the necessary adjustments to the design of the footing and slab detail. Cracking can be mitigated and to some degree if they eventuate will have released the tension in the SOG and once repaired correctly will perform well and also be a visual indicator of the slab movement. Meaning it can be repaired again if need be and is the only kind of floor that can easily be fixed due to access. Cracks in slabs will be mirrored in the tiles if the slab is not fix correctly, I'm sure you have seen such cracks. Around floor wastes and most slab penetrations that have not been 'lagged' cracks will happen. I don't know the cost of an engineer 'on the square', but I do know that at $200sq/mtr you will be getting an absolutely HOLLYWOOD finish. The time on site is enormous and the risk is omnipresent, the cost of diamond wear is huge and runs into the 10s of thousands on some jobs, there are no tutorials, templates, undo buttons and there are actual difficulties, anomalies and many years of training required to get to the end of the job. and sometimes you don't get paid. Every trade has it's own importance and none should be overlooked, most are willing to work together once a 'known' condition occurs.

But I was wondering anyone knew what Perth Builders allow polished concrete flooring? We have asked Summit and Dale Alcock. Summit came back with a flat no. And dale Alcock said we can do it post handover. Anyone else done it using these builders? I don't believe it is something that can be done post handover?.. Spam deleted Well Joe Unless you warrant/guarantee/insure your work then most people are sketical pariculary Engineers and Builders. I learnt a lot from old Grano workers too..particularly what not to do and what clients should be on the look out for. Here a few things they dont tell you but I will! 1.Specifications ie. Check site compaction, mesh, cover and grade of concrete get it in writing and check where's the data, 13 blows/300mm?, SL62?,25mpa, etc.etc 2. Check the middle of the slab it should be uniform thickness during the pour, Ive seen instances where sand mysteriously appears from no where. I'm guessing sand's free around the site while concrete costs $250m3 3. There is a whole book on analyzing crack patterns (plastic failure), I've often heard grano workers say to me (engineer), where's the concrete going to go, no-ones hurt, my rely is "I pour it to the correct speci's so should you"! 4. LOL ask him for 2 quotes one the ganno worker doing the engineering and another where the slab is going to be inspected and certified by an engineer..LOL, really they should be both the same ..but they maynot be?. 5. there is heaps more...Water content,compaction,concrete drying? Yeh i am passonate about concrete too mate, it is the cheapest and most widely used building material in the world..
