Block paving colour swatches
Colour variations can occur within packs, therefore:
Ensure your sample and blocks are from the same factory. Block paving should be ordered from the same batch number to avoid colour variation. Do not mix blocks from different factories. Bradstone cannot accept responsibility once blocks are laid from different batches. Best results are achieved through mixing from 3 to 5 different packs and from vertical columns rather than horizontal rows.
We recommend a neoprene faced or rubber sole plate on vibrating plate compactors to reduce scuffing (specifically on our Stonemaster and Woburn Original ranges). Light colours are susceptible to staining and care should be given when selecting blocks for driveways.
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. 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.
