Driveways are constructed according to your area's building code requirements. We use Base material (crushed concrete) to make a strong and stable foundation for brick or stone pavers. Once the pavers are installed, they are rolled or tamped to help the pieces interlock with each other. The border course is laid on a small concrete footing and the outside edge of the driveway border course is mortared into place. Sand is again applied over the driveway and brushed into the interlocking spaces. The whole interior pattern is again tamped at this time.
