  • -On average $80-$120 per metre square. This cost can vary a lot depending on a range of different factors that could impact how long the job could take.

    -How many m2 to be undertaken? If there is any floor prep to be done first eg. levelling, repairs.

    -What is access to the job like?

    -What depth do we need to grind down to achieve the result the client is after.

    Is it mechanically polished concrete or grind and seal. This is merely just a guide to understand what we look for when quoting, we will always be upfront

  • Concrete can be a fickle material that can crack at any point in it’s lifetime, due to earthquakes or land movement but most cracks are repairable. This can be a natural response to any surface tension often created by moisture evaporation, once poured and temperature changes.

    The perfect concrete mix will go a long way in ensuring a flawless finish slab, too wetter mix and the concrete will over hydrate, causing shrinkage cracks and a too, dryer mix, will create weak crumbly concrete.

    There are actions that can be taken to mitigate against the extent, of cracking. From good subfloor preparation, proper curing of the concrete, and avoiding excess water in the mix but most importantly good foundation compaction.

    Control joints are designed to allow limited movement which relieves the stress caused by shrinkage of the slab and movement of external forces. This system can work firstly by understanding where cracks are likely to occur, narrow sections of slab, shower bases from corners.

    At the end of the day you can mitigate the chances of concrete cracking, but rest assured there may be cracks even if they’re not obviously visible.

    The great thing about polished concrete is cracks can be repaired. Whether it be fine hairline, to larger cracks. There is a product or system that will not draw your eye away from the attraction your polished floor creates.

  • Given the high glossy look that polished concrete creates it is understandable your initial thought is it looks slippery. Despite their smooth appearance polished concrete has great slip resistant properties. That is why it’s used in supermarkets.

    However like any hard floor surface if you add puddled water or mud it can become slippery and will need cleaning up. If non-slip concrete is required we can do a matt finish non-slip surface for external and wet areas.

  • Yes they can and quite simply. Unlike polyurethane or painted floors, polished concrete can be repaired, filled and re-polished in isolated spots, without having to re-coat the whole floor.

  • It can do, but like all things it requires maintaining and anything aggressive that spills on it needs to be wiped up immediately, ie red wine or anything acidic.

  • It can be, in old houses that are built at ground level with no insulation underneath and a high water table in winter, the ground temperature can transfer to the concrete floor. In new houses where the foundation is raised off the ground and insulated ie, polystyrene and plastic is used and the house is insulated with double glazing etc, after the new house moisture content has stabilised and the sun has warmed the slab, new home owners report that the concrete floor remains a stable temperature and does not fluctuate between summer and winter.

  • Yes very durable, the most cost effective, hard wearing surface there is eg. supermarkets.

  • Yes because it’s all made locally, not imported and lasts a long time. It’s using the original structure of the building and you don’t have to put anything over the top of it.

    When polished its dust free, fire- proof and flood-proof.
