Conventional infill
Many sports-turf systems use stabilising and/or performance infill as part of the tested field construction. Infill quantity, material, depth and maintenance remain system-specific.
- Can contribute to fibre support and surface stability
- May form part of the tested performance construction
- Requires an operating plan for distribution, decompaction, contamination control and top-up
Reduced-infill
Reduced-infill systems aim to use less infill while retaining the required field behaviour. They are not simply conventional systems with material removed.
- Turf construction may change to support lower infill quantities
- Maintenance requirements can differ
- Performance claims must relate to the exact reduced-infill construction
Non-infill
Non-infill systems remove conventional performance infill from the playing surface, but they still require complete-system review.
- Fibre and backing construction become especially important
- Shock layer and base interfaces may carry more of the system response
- Cleaning and fibre management still matter
What not to assume
A field should not be converted from one infill strategy to another by changing only one layer unless the complete construction has been reviewed for that use.
