Surface drainage
Water must be able to move through or across the playing surface as intended by the selected construction. Seams, infill, contamination and maintenance can all influence real-world drainage behaviour.
Base drainage
The prepared base and drainage network need to receive and discharge water without creating soft spots, ponding or trapped moisture.
- Review finished falls and tolerances
- Understand sub-base permeability
- Coordinate collector drains and discharge points
- Allow for local rainfall intensity and site constraints
Replacement fields
Replacing turf does not repair an underlying drainage problem. Existing-field projects should review historic ponding, blocked drains, settlement and base movement before the new surface is installed.
Tropical and high-rainfall sites
Heavy rainfall and high humidity increase the importance of drainage capacity, maintenance access and contamination control.
