Does Non-Infill Turf Need a More Precise Base?
In many applications, yes. But the reason should be explained carefully. It is not simply because “non-infill turf has no infill.” Rather, non-infill systems rely more directly on the engineered turf structure and installation system to provide the required surface characteristics. Therefore, deficiencies in the underlying foundation can have a greater effect on the finished surface. For…

What About Expansion Joints and Cracks?
Concrete bases naturally require careful joint design. Existing joints should not simply be ignored when artificial turf is installed. The project team should determine: Covering a structural problem with artificial turf does not eliminate the underlying movement. If the base continues to move, the turf system may eventually reflect that movement. 12. Base Acceptance Checklist…

Don’t Install Turf on a Wet or Unstable Base
A good drainage system is more than simply giving the surface a slope. The complete system may include: surface slope + permeable layers + drainage channels + perimeter drainage + subsoil drainage Depending on the design, surface gradients around 0.2%–0.5% may be encountered in sports-field projects, but the actual slope must be determined by the engineering design…

Asphalt Base: What Should Be Checked?
For asphalt foundations, contractors should pay particular attention to: A high-quality asphalt surface can provide a suitable foundation for artificial turf, but the asphalt must be properly compacted and sufficiently stable before turf installation. Again, a generic “95% compaction” figure should not replace the project’s engineering specification and testing requirements. 8. Flatness Is One of the…

Concrete Base: What Should Be Checked?
For concrete foundations, commonly specified considerations include: Concrete strength A project may specify a strength class such as C25 or higher, but the correct concrete grade should come from the structural and civil design. Surface flatness The surface should be checked systematically before turf installation. A specification such as ≤3 mm deviation over a specified straightedge length may…

Prepare and Compact the Subgrade
The first layer is the natural soil or engineered fill. Before installing the aggregate layer, contractors should address: The subgrade is then compacted using appropriate equipment. A commonly encountered project specification may require a compaction level around 93% or higher, but this should not be treated as a universal requirement. The appropriate target depends on the…

Why Is the Base So Important for Non-Infill Artificial Turf?
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: Settlement → wrinkles and seam problems If the subgrade or aggregate layer is…

Children’s Areas and Kindergartens: 20–30 mm
For children’s areas, pile height should not be treated as a direct indicator of safety. The critical question is whether the complete surface system achieves the required impact attenuation, vertical deformation, drainage and other safety requirements. Depending on the jurisdiction and project type, standards such as EN 1177 and applicable national playground or sports-surface requirements may be relevant. For…

Why Pile Height Should Not Be Selected in Isolation
1. Pile Height and Tuft Density Work Together In traditional infill artificial turf, sand and rubber or other infill materials help support the synthetic fibers. A non-infill system does not have this loose support layer. Instead, the upright performance of the turf depends more heavily on: This creates an important relationship: The taller the pile,…

Turf Thickness Specification Checklist Before Comparing Products
A gym turf specification checklist turns a stack of quotes into comparable data. Record the same fields, in the same units, for every product before you rank them. Without that discipline, comparing a pile height from one supplier against a total figure from another produces a false conclusion. Dimensions, inclusions, and measurement conditions to record…
