Abstract
A flexible modular trench includes an open-faced channel extending along a central axis between a pair of axial ends. The open-faced channel includes a pair of axially-extending shelves connected by a trench wall. The trench wall has a smooth inner surface and a corrugated outer surface. The corrugated outer surface has corrugations extending along a plane perpendicular to the central axis to allow for increased flexibility such that the flexible modular trench is bendable in a direction perpendicular to the central axis.
