| Step 3: | Base course Add a layer of 20mm (3/4") graded base course metal in between the edging boards. 20mm (3/4") graded means the metal is graded to 20mm (3/4"), and everything below this size is included in the product. Add and compact the base course with a mechanical plate vibrator until the finished height is 85mm (3 1/2") down from the top of the edge boards. At the same time compact the soil against the outside of the edge boards thus ensuring they stay in place parallel. You can hire a plate vibrator from your local hire center. |
| Step 4: | Bedding sand Add a 35mm (1 1/2") layer of bedding or paving sand, and level with a screeding board so the finished height is 50mm (2") down from the top of the edge boards. |
| Step 5: | Laying the paving stones Commence laying the pavers from one end of the path. (work uphill). Space the pavers approx 3 mm (1/8") to allow filling sand to penetrate around the pavers. Kneel on a board across the area you have already laid. Use full pavers only, go back later and fill in with the cut ones. |
| Step 6: | Compacting and putting in joint sand The pavers should now be, prior to compacting, 10mm (3/8") above required finished height. Compact the pavers consistently with the plate vibrator. The final step is to brush jointing or filling sand over the surface. This fills the joints and binds the pavers together. Vibrate again. |
