Application

Suitable for outdoor environments subject to heavy footfall such as leisure complexes, theme parks, holiday resorts or other public points of interest.

IMPORTANT: All specification information must be checked against the individual site requirements. Flowcrete advises that specifications are confirmed with their technical experts.

Description

A slip-resistant bonded gravel system, used primarily to surface outdoor areas, whereby a range of natural stone aggregates are scattered into a solvent free polyurethane resin binder. It offers an alternative to block paving eliminating the cracks where weeds can grow and dirt can dwell.


Features and benefits:

  • Slip resistant profile.
  • Capable of withstanding heavy footfall and vehicular traffic.
  • Available in a range of natural stone aggregates.
  • Alternative to loose stone and/or gravel.
  • Easily cleaned and maintained.
  • Chemical resistant: high resistance to tea, coffee, cola, fruit juice, soaps and bleach.
  • Capable of installation over ‘green concrete’.
