Thought I'd heard/read on here that in certain instances it is acceptable to install pavers directly onto screeded bedding sand with NO base...true? I've got a 1600 sq/ft pool surround/courtyard built on pure sand...it's literally like being at the beach. There is no end in site to the sand depth...sideyard looks like a dune etc... I've already quoted/signed the job (factoring my standard 4" compacted base)...but now I'm wondering if I can provide a warranted, quality installation with this alternative installation method...if it exists. Also - if true how does the edge restraint perform when the base is pure sand? Seems shaky to me. I'm very curious what the more experienced guys - especially guys in the Florida and southwest are doing. I'm not going to do it unless there's sufficient supporting evidence. Thanks.
