Naturewalk System
Verified by manufacturer over a year ago
Seamless and slip-resistant bonded gravel system.
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’.
