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.
