Artificial turf follows the geometry of the surface underneath it.
If the foundation is poorly prepared, problems can eventually appear on the finished turf surface.
Uneven base → uneven turf
Local depressions or high spots can become visible through the turf, producing:
- Waves
- Low spots
- Uneven playing surfaces
- Localized water accumulation
Settlement → wrinkles and seam problems
If the subgrade or aggregate layer is inadequately compacted, differential settlement can occur.
This can contribute to:
- Turf movement
- Wrinkles
- Edge lifting
- Seam stress
- Localized depressions
Poor drainage → standing water
A turf system can drain well only when the underlying base and drainage system are properly designed.
Insufficient slope, blocked drainage paths, or an unsuitable sub-base can result in prolonged standing water.
Freeze-thaw conditions → additional stress
In cold climates, water trapped in the foundation can freeze and expand.
Repeated freeze-thaw cycles can contribute to:
- Heaving
- Cracking
- Settlement
- Surface deformation
Therefore, good artificial turf starts with good civil engineering.
