From maximum exposure to a polished lustre, there are a variety of
finishes that can be achieved with Geostone decorative concrete.
Geostone’s decorative concrete is a stunning
material to work with, for both indoor and outdoor applications. By applying various levels of honing, anything between a rough exposure and smooth polish can be achieved.
For maximum exposure of the coarse aggregates, the depth of honing should be approximately half the maximum nominal size of the coarse aggregates where progressively finer abrasives are needed to produce a ‘polished finish’ having a surface lustre.
Showcasing how architects around Australia have applied Geostone concrete to both residential and commercial projects.
Your questions answered
The process of exposing aggregate and grinding polished or honed concrete floors produces sensitive waste materials such as cement slurries, care should be taken to retain all waste on site and then dispose of it in a responsible manner. Contact your local council for more information.
For further information please refer to our Best Practice Placement Guide or contact your local Geostone representative.
The level of exposure can be controlled; light exposure reveals a few stones in the surface while heavy exposure creates a more coarse effect with more stones protruding from the surface. Make sure you discuss the options with your installer before starting your Geostone project.
We recommend resealing your Geostone concrete every 2 years to keep it looking the way you want it to. Keep in mind this depends on the amount of traffic and resulting abrasion on the concrete surface.
To protect your Geostone concrete, it is recommended to seal the decorative concrete surfaces. Read more on sealing here. Decorative concrete is quite easy to look after. Click here to read more tips for cleaning decorative concrete.
As concrete is a porous material it can absorb contaminants which can lead to staining if not treated. Not all installers include sealing as a standard so make sure you ask your installer about sealing at the outset of your project.Click here to read more on sealing your decorative concrete.
Control joints are placed in the concrete to encourage any cracking that may occur to happen in predetermined locations, allowing the customer to control to an extent where the cracking happens and reduce cracking as much as possible given the terrain.
We recommend that control joints be cut to a minimum of 25% of the concrete depth in order to be effective.
You can read more on control joints in our Best Practice Placement Guide.
We recommend that control joints be cut by trowel or jointing tool whilst the concrete is ‘plastic’, or by saw no later than 18 hours after the concrete is laid. While control joints can be cut by saw, this can introduce unwanted moisture into your concrete which can later produce a milky colour on sealed concrete. Saw cut joints may also introduce foreign material such as sand which can allow weeds to grow causing the edges of the concrete to crack. Commercial coloured seals are available to cover saw cut joints and prevent these issues. Alternatively, your installer may supply one of several commercial jointing products.
As concrete is highly alkaline, the steel will not rust provided that it is fully encased by the concrete. The reinforcing mesh should be placed a minimum of 25mm away from the concrete surface to ensure it won’t come into contact with the atmosphere.
You can read more on the risk of rusting in our Best Practice Placement Guide on page 2, linked below.
