What happens here
Following initial excavation and utility work, the final stage before laying pavers is the preparation of the sub-base. The narrator states this involves 'all the groundwork for the base before we start putting stone.' This typically includes applying a geotextile fabric, laying down and compacting layers of crushed stone or gravel, and then adding a bedding layer of sand or fine aggregate. Each layer must be carefully leveled and compacted to create a stable, well-draining, and durable foundation for the Unilock blocks.
Goal: Create a stable and level base for the paving stones.
Tools and materials
- Laser Level or String Line — Ensuring accurate elevation and slope of the base layers
- Plate Compactor — Compacting gravel and sand layers for a stable base
- Rakes and Shovels — Fine grading and spreading of materials
- Skid Steer Loader New Holland — Spreading and leveling base materials
- Bedding Sand — Providing a level surface for paver installation and aiding drainage
- Crushed Stone/Gravel — Creating the main structural base layer
- Geotextile Fabric — Separating the sub-grade from the base material, preventing intermixing and improving stability
