How does interlocking a driveway compare to paving in terms of cost?

Asphalt now costs approximately $3.50 per square foot. It is usually sealed every year at a cost of $0.35/sq. ft., and should be replaced every 8 years or you will not maintain a kept look. Interlocking brick is installed once at a cost of $13.00 per square foot (commonly ordered brick). A sealer, which is recommended to reduce the time and cost of maintenance is $1.25/sq. ft. Yearly maintenance is minor and can be done for little or no cost. Repairs are covered under warranty for 2 years, following that, should you require a repair, we estimate it at no more than $1500.  more
