Beautifully natural

Concrete is made from natural materials, and this means the surface has character as it is naturally variable - one of it's key design benefits. From experience we know that the inherent natural properties of concrete are not to everybody's taste and it is important you understand the following.

Workmanship is a key part of the outcome and we encourage you to choose a reputable contractor.


Concrete has a characteristic mottliness or cloudiness and our colours often highlight and extend this. It is unlikely to be uniform colour but this is part of the appeal. This gives the space a natural element - one of the key design features of concrete.

Our colour samples are unlikely to match the final result

The colour of normal concrete, even without added colour pigment, varies with a number of factors like raw material colour, weather conditions on the day, how it is handled and placed, and how it cures and dries.

The colour we make is absolutely consistent but when it is added to concrete the same normal variations can occur as above - the tone is the same but the shade may vary.

Plus, our samples are cast in a mould so the texture will not represent the surface on site.


Shrinkage crack in concrete

Concrete shrinks when it dries - so Construction Cuts are made at around 4m spacings soon after placing to provide a point of weakness in the slab, and control where the cracks to occur.

But, there is always a chance that cracks can occur where they are not desired. A good concrete contractor will take steps to minimise the risk, but it is always possible.

Cut locations should be considered during the design phase. We offer a service to recommended where Construction and Decorative Cuts should be made and encourage you to use this - just email us your plans


Occasionally following sealing, some concrete surfaces may get dark patches when wet, that disappear upon drying.

This is called 'measling' and is caused by microscopic holes/cracks/high-points in the sealer that allow small amounts of water into the concrete. It only happens from time to time and is the result of concrete being concrete, not bad workmanship or faulty materials

Over time the effect will be come less and less. To fix, we suggest topically applying more coats of sealer - sometimes many coats - but be careful not too add too many over large areas as it may increase slipperiness.


Very occasionally a phenomenon called Pinto occurs in concrete, regardless of whether colour is used or not. It's not known the exact mechanism but it seems to be related to the curing of the concrete ie how it dries and how moisture moves through the slab.

Ensuring consistency of placing and curing across the slab should help to prevent it.

It's very difficult to fix, but sanding the surface then applying a light acid wash, may reduce the effects.
