Block paving is very durable and is expected to last reliably for at least 20 years. It is a great material for a driveway or patio as it is incredibly hard-wearing and, as such, can easily cope with lots of motor and pedestrian traffic. In fact, it is able to withstand so much pressure that it is commonly used in airports and docks – a testament to its capabilities. Additionally, it is unaffected by frosts, salts, oils and most chemicals, making it a popular choice in heavy industrial sites.
