LAYING THE GRAVEL
Lay the gravel. We advise against moving loads across unfilled gravel sheets. Level with a shovel, brush, rake, and tamp. Do not compact the decorative gravel. Allow the gravel to exceed the plates by 1 to 2 cm (1cm for finer and 2 cm for coarser types of gravel). The gravel will sink slightly as a result of natural compaction. Eventually, there should be just enough gravel to hide the ECCOgravel® sheet.
For vehicular applications, we recommend a grain size of 8 to 16 mm (smaller types of gravel get stuck in tire treads, while larger grain sizes are aesthetically less pleasing).
For non-vehicular applications we recommend a grain size of 4 to 8 mm (smaller types of gravel will pulverise over time).
