Dry laying on gravel mixed with cement can be used for applications such as garden landscaping, patios, courtyards, walkways and terraces for a more stable surface than a completely dry installation, but it will not be possible to easily lift and replace pavers.
1
Step One
After defining the area to be excavated, mark the perimeter using wooden or steel marker posts connected by a string. Note that the excavated area should be extended on all sides by approx. 6”-8” to ensure stability at the outer edges of the paved area.
2
Step Two
Remove the soil inside the marked area using a shovel or excavator. The depth of excavation will depend on several factors including the anticipated loading, the drainage capacity of the soil and the soil conditions in general.
3
Step Three
Using a rake or shovel, level the excavated area and ensure there is at least 2% slope for good drainage. Compact the soil with a vibro compactor.
4
Step Four
Fill the excavated area to a thickness of 8”-12” with a layer of sand or fine gravel, depending on the planned loading. Compact the sand/gravel with a vibro compactor and ensure that the 2% approx. slope for drainage is maintained.
5
Step Five
Mix gravel of size 3/16”-1/4” with 5% cement and a small amount of water and place over the compacted gravel layer to a thickness of 2”-4”. Use a trowel to level the surface and if the joints between the pavers are not to remain as permeable, ensure there is slope of approx. 2%.
6
Step Six
For optimum adhesion of the pavers to the bedding layer, specialized thinset mortar can be applied to the underside of the pavers.
7
Step Seven
Carefully tap the pavers with a rubber mallet to ensure they are bedded properly into the gravel/cement mix and that they are level with each other.
