The foundation concrete can be poured directly into the excavated
hole. Concrete specifications:
- Class C30/37.
- Concrete with aggregate 10-30 pursuant to UNI EN 12620
- The bollard must only be installed once the concrete has cured
for at least 7 days.
The compaction index of the surrounding soil should be at least 90%
of the optimal "Proctor" curve, pursuant to the UNI EN 13286-2:
2005 standard.
The steel reinforcement complies with the B450C class (ASTM A615
Grade 60).
!
Whilst the concrete is curing, insert one or more of contrast supports inside the pit, to prevent the walls from bowing inwards
due to the load of the fresh concrete.
