Tunnel segments

Tunnel segments are precast reinforced concrete units that mate with one another, forming a truncated conical ring. Tunnel construction using precast ring segments as wall coverings allows the tunnel to follow curves, in both the horizontal and the vertical planes. This is because the rings are in the shape of truncated cones. When the convergent faces are placed together contiguously, a curved alignment is produced.

We have the facilities to carry out any project, regardless of its scope.
