DURAFLOW™

 

Recommended Base Stabilization – one layer of DriveGrid™" stabilization grid (or as specified by engineer) between subgrade and base material. Use Permeable Base Gravel. Recommended depth 8” to 10” below pavers for maximum stability and performance OR as specified by project engineer. 

Permeable Base – Min. 6” – 8” of ¾“ clear (ASTM No. 57) open-graded stone compacted to achieve full particle lock-up and consolidation. (Clear open-graded does not compact but does consolidate slightly by rattling the particles together.)

Permeable Bedding Course – 1” thick of 1/4” clear open-graded chip stone – (ASTM No. 8 or 9) screeded over base.

 

Jointing Materials - 1/4” clear open-graded chip stone – (ASTM No. 8 or 9)

Handling – Always keep site clean during construction to prevent site debris from clogging up the permeability of the paver.

Edge Restraint - Always install an edge restraint around the perimeter of any paver installation not restrained by building structures. Spike-in edge restraints come in plastic and metal and work well for most applications. A concrete curb or a sub-surface concrete wedge can also be installed to retain the edge.

Paver Compaction - Always use a protective polymer pad on the bottom of your compactor when doing the final compaction of the pavers. An alternative is to use a rubber-roller compactor for the final compaction.  No compaction is required if installed on roof deck pedestals.

Cleaners – Any cleaner specifically designed for pavers may be used for color restoration or general cleaning. Follow manufacturer’s dilution rates and application procedures. Always test a small area to make sure the results are as expected.

 Sealers

  • Product may be sealed for aesthetic or cleanliness reasons but it is not required
  • Use any sealer approved for concrete pavers
  • Select type for desired aesthetics
  • Product must be cleaned before sealing
  • Always read and follow manufacturer’s application procedures
  • Always test a small area to make sure the results are as expected
