ES CULVERT
ES CULVERT
Features
Reduced cost compared to conventional methods
Cost can be reduced compared to the conventional on-site box culvert method.
Shortened construction time
Factory-processed, ES Culvert can be assembled easily and worked quickly, thus enabling a significant reduction in construction time.
Compact, lightweight sections offer superior transport and handling
Each section is compact and lightweight to enable easy transport, even at sites where it is difficult to carry in materials.
Adapts to bearing ground settlement
Because ES Culvert has excellent adaptability to settlement in the vertical direction, the required properties of the bearing ground can be minimized.

(Note)
When studying cross-section for actual applications at site, decisions should be made by taking into account factors such as paving method and ancillary facilities. We also support structural dimensions other than those indicated above. |
