Paving stones contractor: designers, installers Long Island NY
By Giuseppe Abbrancati
Gappsi driveways are installed on 12 inches of RCA and 1 inch of sand. The RCA base is compacted with Vibratory rollers and heavy plate compactors. After the paving stones are installed joints are filled with regular or Polymeric sand and are then compacted again with a small mechanical plate compactor.
The last application allows the joint between pavers to fill and create the interlocking paving system; it also allows the pavers to be leveled by pushing any thicker paving stones down into the sand base below.
A Gappsi paving stone driveway can be used right after completion of the compaction.
