Designed to withstand challenging outdoor conditions, these precast units help ensure structural stability, wind resistance, and long-term performance across a wide range of farming applications.
What Are Counterweight Blocks (Kelly Blocks)?
Secure Polytunnels Against Wind and Movement
Polytunnels are exposed to significant environmental forces, particularly wind uplift and lateral movement. Ballast blocks provide:
Stable anchoring without ground penetration
Resistance to wind uplift and structural displacement
Additional weight to maintain structural integrity
This ensures polytunnels remain secure, functional, and protected in all weather conditions.
