For indoor multi-sport halls, performance consistency depends heavily on subfloor preparation and installation precision.
Subfloor preparation
- Flatness tolerance: ≤2 mm under a 3 m straightedge
- Base strength: C25 or above
- dedicated moisture barrier treatment recommended
Indoor ball behavior and user comfort are highly sensitive to surface flatness. A tighter flatness tolerance than many outdoor fields is therefore essential.
Material control before installation
Vivaturf’s recommended quality workflow includes verification of:
- anti-static performance
- acoustic reduction properties
- odor / VOC profile
- fiber height consistency (±2 mm)
- density variation (≤±5%)
Installation
- environmentally responsible low-odor bonding method where required
- seam bonding strength: ≥2.5 MPa
- reinforced edge detailing with thickened backing and secure edge profiles
This helps ensure long-term safety and prevents edge movement or seam instability.
Post-installation verification
For indoor venues, handover should include checks for:
- shock absorption
- vertical deformation
- ball rebound
- anti-static performance
- odor / VOC profile
- uniformity across zones
This is especially important in multi-use halls, where inconsistent performance can compromise the value of the venue.
