Re: Polished concrete disaster 9Sep 18, 2021 5:18 am Hi Sarah, I have just gone through exactly the same thing and would love to hear how you went with this as I have a tribunal meeting in a few weeks. Its heart breaking that a huge part of your home looks like this.. sarah452 We've recently had our lovely, expensive 32MPA slab with aggregate "polished" with disastrous results! Our project manager asked a separate polishing sub-contractor for a "polished concrete" finish but what we have actually received is a grind and seal. No one explained to us that there was a difference between "true" polished and a grind and seal. That aside, the finish on their so-called grind and seal is appalling. We have a dark oxide base with bluestone aggregate and the slab has multiple cracks through it (which we were told can occur and it seems we have been unfortunate). Without asking us, the polisher has filled the cracks with light grey filler. It is as if he has run a great streaks of white paint (up to 3 metres in length) all over our dark concrete. They have failed to fill most of the holes and pocks in the surface - some are up to 10mm in width and 5mm in depth and they are EVERYWHERE. To make matters worse, they have left deep circular grind marks around the perimeter of the space. Now that we have seen the floor, we've insisted to the polisher (and the project manager) that we asked for a "polished concrete" surface and have offered to pay the difference in cost between the two finishes. The polisher, however, is asking us to pay for the $4000 we initially agreed upon, and then wants to charge us an additional $140sqm (his "true" polished concrete cost) to grind everything off and start again! My question then is - is what they have done so far even an acceptable result for a grind and seal? I am loathe to pay them $4000 for a sub-standard surface that they are just going to grind off. We would love some second opinions - photos of the work can be seen here: http://hindsight.net.au/photos/ To my understanding early saw cuts are to control shrinkage cracks, so doing them now would be pointless. Control joints may reduce ugly cracking during periods of soil… 3 9829 Hi all I need a guidance on how far I need to space expansion joints in the concrete driveway and its type (keyway/foam.) Contraction joints are at 3m max for a 125 slab. Thanks 0 10921 |
