The best type of block paving is very subjective since it not only depends on your particular taste but also the function for which the block paving is being used.
What we can say is that the most popular type of block paving is 200 x 100 x 50mm and is the most common type used on driveways throughout the UK.
It is generally laid in a herringbone pattern in either 45° or 90° degree angle from the house. This is achieved by pulling a 90° string line off the house and laying the paving either square off the line or at 45° (V Shape).
The same applies to the best colour for block paving where it depends on your own particular preference and the style of your house. The most popular block paving colour is the brindle colour where a charcoal block paving is used as the border for it.
As for manufactures, the most common and popular block paving manufacturer in the UK is Marshalls, followed by Brett and then Tobermore. Each produces a high quality paving product and similar variations of colour and products.
