Overview
Replace solid tiles with permeable pavers or gravel over graded base layers; optionally add storage crates beneath.
Pro / Contractor€€€High runoff reduction
Materials
- Geotextile separator
- Open-graded subbase (e.g., 32–63 mm)
- Open-graded base (e.g., 4–32 mm)
- Bedding layer (2–6 mm)
- Permeable pavers or gravel
- Edge restraints
- Optional: modular storage crates
Tools
- Plate compactor
- Laser level / straightedge
- Cut-off saw (for pavers)
- Rake, screed board
Safety & Risks
- Wear hearing/eye protection with saws/compactors.
- Dust control when cutting pavers.
- Mind underground utilities before excavation.
Maintenance
- Vacuum sweep annually to remove fines.
- Top up joint aggregate as needed.
- Fix settlement promptly to avoid trip hazards.
Permits / Notes
- Driveway changes often require permits and drainage checks.
- Consider accessibility slope requirements.
Steps
- Remove existing paving and excavate to design depth with slope to drain.
- Place geotextile; install subbase and compact in lifts.
- Install base and screed bedding layer level.
- Lay pavers with tight joints; fill with 2–6 mm aggregate.
- Compact surface; top up joint aggregate.
- Test infiltration; ensure edge restraints are secure.
