Sand is used as a bedding layer between the pavers and the compacted gravel base. The standard thickness of the bedding layer is 1 inch thick.
Putting sand over the river rock, eventually the sand will settle between the rock and will not settle in evenly making the patio or walkway become uneven.
Use the river rock in flower beds instead of mulch, as fill when making a drywell, anything else other than a base for pavers no matter what size they are
Thanks for the info. That makes sense.
What would you recommend instead of river rock (wondering if I have to purchase the bags of whatever expensive, compactable rock the local home improvement place tells me...or do I have other options)?
Could the river rock be used under concrete?
