The length of time a brick driveway lasts really depends on what is underneath and what kind of base the original home builder installed. If done properly I have seen brick driveways that have lasted 30+ years. Underneath the bricks the base should contain a few inches of either bedding sand or limestone screenings (chips and dust) and at least 1 foot of gravel. Sometimes under pressure, hurrying home builders may skimp out on that foot of gravel, which weakens the base and length of time it will last. At the request of the customer we can look at adding more gravel to that base. Every driveway is different so generally we tell customers they can expect their driveway to last about the same amount of time it has lasted until now plus a bit longer.
