Concrete colour and maintenance

Colours may vary subtly, especially in blended shades.
Colours will appear different during varying weather conditions such as sunlight and rain.
Please check colour samples in dry conditions and in full daylight. Where possible, products should be selected from the same product batch.
Our Peak paving should not be used for patios or areas where aesthetics are important.

Slurry Primer

The British Standard recommends that a slurry primer (should as Bradbond) should be applied to the underside of all paving prior to laying to improve adhesion

Differential Weathering

Differential weathering can cause patchy dark discolourations on the surface of individual units. Again this will generally diminish over time and will not affect long term
performance. This is due to differential weathering where the surface of the paving has cured at different rates. All decorative products will weather and change appearance
over time.

Efflorescence

Efflorescence can appear on all paving products as white patches or a lightening of the surface colour, but seems to disappear when wet.
It is formed by a normal chemical reaction which causes calcium hydroxide (lime) to migrate through the damp paving surface and then react with carbon dioxide in the atmosphere resulting in a deposit of calcium carbonate crystals. Efflorescence is very unpredictable in its occurrence and can happen at any time of the year but is more prevalent in winter.

Although there are cleaners available, efflorescence is a natural phenomenon and will generally disappear with the natural weathering process and the passage of time. It does not compromise the integrity of the paving. Aggregate Industries cannot accept responsibility for the effect of efflorescence which can be a characteristic of all good quality products with a high cement content.
