How to calculate the exactly needed quantity of Geocell connection key?
It should depend on 2 factors:
1, The expanded panel size (also means length x width).
2, The project needs to connect 2 sides or 4 sides.
For example: Geocell type HF100-445/ quantity 15060m2, total 600pcs.
Welding distance 445mm
Expanded cell size: 320x288mm
Standard expanded panel size: 2.56×9.8m
Expanded panel area: 25.1m2
Welding direction: 8cells
Overlap direction: 34cells
So if 2 sides connection, you need connection key: 34×600=20400pcs
If 4 sides connection, you need connection key: (8+34)x600=25200pcs
