If you are renovating your home and planning on building a house extension to add more space then it makes sense to also consider the type of flooring you will have for your interior design. Haynes Polished Concrete is a concrete floor polisher in Melbourne that can provide either a grind and seal service or mechanical polished concrete floor polishing for your existing slab.

This home in Bendigo, Melbourne had an existing concrete slab foundation and instead of using floor boards, carpet, tiles or lino the owners chose to get all the concrete flooring in the home mechanically polished. They did consider tiling or installing floating timber floor boards but after doing their research they discovered the best choice for their home renovation was to get their concrete floors mechanically polished. 

Choosing to get mechanical concrete polished floors is a premium choice over a standard grind and seal, even for existing concrete slabs. You end up with a beautiful smooth floor that is suitable for a museum or high end luxury retail store. It is very easy to get your concrete polishing for an existing slab in a home, what we do first is a concrete grind on the whole area to make sure it is level, smooth & all free from any blemishes. If we find any cracks we will repair them as best we can before we do any polishing. Once we complete that process we can then begin the mechanical polishing process using our machinery to polish the surface to your chosen gloss level.

The cost to get mechanical polished concrete in Melbourne for this type of site was approximately $9,000 ex gst which works out to be roughly about $110 per square metre for the 90 metres of floor space that had to be polished. As you will see in the photos all the living, kitchen and dining area had polished concrete floors done.

Concrete slab floor polishing for home extensions in Bendigo, Melbourne

More and more people are getting their existing concrete slab floors polished in Melbourne. It continues to increase in popularity as people realise all the great benefits this service can provide. Polished concrete floors were used in this home even though the slab was old, it’s possible to convert existing floors to be polished concrete. You can remove the carpet, lino, floor boards or even tiling to then work on the concrete surface underneath. For homes in rural areas one of the other big benefits of polishing all the concrete floors instead of covering them with other materials is the improved fire resistance the structure will have.

As you will see in the photos there are imperfections in the surface like small cracks or slight changes in the amount of aggregate that is exposed and this is due to the the way the existing slab was poured & has aged over time. Once we grind the surface we can make it as smooth as possible but you may still see slight imperfections which is normal.

Concrete floor polishing for a kitchen or living area

There was a time when it was unusual to see a polished concrete floor other than in an art gallery or a retail showroom, but times have changed and this good-looking, hard-wearing flooring service is now more commonly used in family homes, especially when they are getting renovated or extended.

Polished concrete floors are suitable to have either indoors or outdoors in residential, commercial or industrial locations. It is a very versatile flooring choice as it can cater to so many different applications and has the longest lifetime. The salt and pepper grind in this home was finished off with a satin polish so that the old and new parts of the home will match well together as people walk from one room to another.

Polished concrete floors can be installed in wet areas like a bathroom, laundry or kitchen just as equally as they can be used for outdoor areas like a patio, undercover dining area or even your car’s garage. Different finishes will suit different locations around your home. Polished concrete floors work well in contemporary, open plan spaces (as you can see in the photos from this job site). It may not make so much sense for an older property as it may not fit the character of the building, although as ‘The Block’ has demonstrated, it is possible with the right interior design choices. The only consideration is that polishing concrete in smaller rooms with lots of small corner details such as skirting boards can be time-consuming and therefore a bit more expensive to get installed vs larger, opan plan rooms.

For a home getting an extension with an existing slab, there are two main types of polished concrete floor to choose from; 

1) A Grind and Seal involves grinding back the top layer of concrete and then sealing it with a matte, semi- or high-gloss sealant over the top of the existing concrete surface area.

2) Mechanically Polished Concrete floors are ground back, densified/hardened and then polished to the required level of shine which does take longer to do, so is a bit more expensive, but this method is more durable and will look good for a lot longer without much maintenance required.

The aggregate mix for this concrete slab enabled us to provide a salt and pepper finish. Different slabs will produce different results because concrete is made from cement, sand, water and aggregate which is usually crushed stones or rock. The type, size and quality of the aggregate in the slab will affect the strength, durability and weight of the finished concrete as well as things like shrinkage & colour.

Depending on the aggregate mix in your existing slab & the choice of concrete polishing service you choose the results will vary in terms of colour or texture. The only way to control this is to pour a brand new concrete slab where you specify the aggregate mix.

Husqvarna Hiperfloor concrete floor polishing in Melbourne for home extensions

Our company is a Husqvarna Hiperfloor concrete floor polisher. The Hiperfloor system is the true form of polished concrete which is the easiest to maintain. It combines beauty and strength which means that over the life of the floor it becomes the least expensive flooring option available on the market. 

Hiperfloor can be applied to new or existing concrete slabs.

The Hiperfloor process of polishing concrete by Husqvarna is a form of mechanically polished concrete that is backed by a long warranty. There are not too many contractors in Melbourne that can produce a floor to this standard. Like all polished concrete, you can choose to have a Husqvarna Hiperfloor in a matte, semi-gloss or a high-gloss. By mechanically refining the hardened concrete surface through grinding, polishing and chemical treatments, Haynes is a skilled contractor that can transform virtually any surface to a whole new level of beauty, functionality and strength.

Hiperfloor is available in three distinctive surface finishes: Premium, Commercial and Industrial with each one having its own well-defined specification for the working process,  selection of grinding/polishing tools and chemical to be used. You can have minimal stone exposure or you can choose to grind down further to get a more decorative full stone exposure finish. The cost to get Hiperfloor does vary slightly depending on how much stone you want to see, and the desired gloss level. This is simply due to the extra labour involved to achieve the finish you would like.

For this new home build we fully exposed the concrete aggregate to deliver the most aesthetic appeal. Floor flatness, reflectivity and shine are always our biggest priority when we are polishing new concrete floors. There are so many great benefits;

  • Reflective and decorative finish choices
  • Floor flatness 
  • Extremely high quality and durability
  • Hygienic and easy to clean
  • Exceptionally resistant to abrasion from furniture or foot traffic
