Driveways · Practical advice
Driveway construction process
See what goes beneath a block-paved driveway, from excavation and a stable sub-base to edge restraints, drainage, laying the blocks and finishing the joints.
Design the driveway before choosing the pattern
Start with the way the space will be used: parking, turning, deliveries, walking to the door and access to bins or a garage. Establish finished levels and drainage before excavation. The paving pattern is a visible design choice; the supporting construction determines whether that pattern stays even under use.
A written specification should identify the blocks, edge details, supporting layers and drainage approach. The depth and materials need to suit the ground and expected loads, so a single standard build-up is not right for every property.
Prepare stable support
Excavation removes material that cannot provide suitable support and creates room for the specified layers. Soft areas, old trenches and variable ground should be assessed before they are covered. Adding more paving above a weak patch does not remove the weakness.
The sub-base distributes vehicle loads. Suitable aggregate is placed and compacted in controlled layers. Access for equipment matters: edges and awkward corners need proper attention too. Keep a photographic record of these stages, because most of this work will disappear beneath the finished surface.
Restrain the edges and lay the blocks
Edge restraints hold the paved area together. They need to be established securely and coordinated with borders, thresholds and drains. The laying course then provides the specified bedding for the blocks; it is not a substitute for correcting an uneven sub-base.
Blocks are laid to the chosen pattern with suitable joints and carefully cut boundaries. Conventional block paving and permeable block paving use different jointing and supporting materials. The specification must identify which system is intended; ordinary sand-filled paving should not be presented as a permeable system simply because it has joints.
Finish, inspect and hand over
The appropriate joint material and compaction procedure complete the surface. Inspect edges, cuts, cover levels and drainage, and confirm when vehicles may return. Ask which jointing material to use for future maintenance and whether a follow-up check is advised after initial use.
A useful handover explains routine sweeping, spill treatment and drain maintenance. It should also tell you who to contact if movement appears, rather than encouraging repeated sanding over a developing dip.
Common questions
Can existing blocks be reused?
Often they can, if their condition and suitability allow it. Budget for cleaning, breakages, replacement pieces and the supporting work beneath them.
Can the driveway be laid over the old surface?
Only after assessing that surface and the complete design. A new finish cannot make an unsuitable base, poor levels or inadequate drainage sound.
