Another common misconception is:
“Because it is non-infill, the turf can be used immediately regardless of the base.”
That is incorrect.
The artificial turf is only as stable as the system beneath it.
A properly prepared base should provide:
- adequate compaction,
- dimensional stability,
- appropriate drainage,
- suitable flatness,
- correct slope,
- sufficient structural capacity.
If the base has settlement, soft spots or drainage problems, simply waiting longer after installation will not solve the underlying problem.
For outdoor projects, the basic structure can be thought of as:
Subgrade → sub-base → engineered base → optional shock pad → non-infill turf
The exact construction should be designed according to the project.
