An assembly (10) protects an elongate member (e.g., an electrical cable) extending through an opening in a support structure (e.g., a wind turbine leg (12) and passes through at least one bend protector, e.g., a bend stiffener (20a, 20b), and a retaining device (18). The retaining device (18) has a body configured to lock itself to the opening. The body carries an abutment (78) and locking members (84), which are movable between retracted and extended positions. A movable member (86) is carried by the body (82), moveable axially with respect to it, and attachable to a pulling line. As the assembly (10) is pulled into the opening by the pulling line, the abutment (78) engages the support structure and arrests inward movement. The movable member (86) is moved in the inward direction with respect to the body (82), and the locking members (84) move to their extended positions to lock the retaining device in place.

A method of using a fill mask to prevent overfill and/or spillage of a fill material from bonding to the roadway surface or staining the roadway surface during filling of a microtrench.

A high pressure cable reinforcement sleeve is provided having two or more bracket elements that are capable of forming a sleeve for surrounding a cable joint, wherein each bracket element has an outer wall and at least one inner protruding wall element.

Methods and apparatus for cutting a trench (e.g., for a fiber optic cable or wire conductors) in an existing covering surface (e.g., a road surface). Debris from the cut trench is evacuated (e.g., vacuumed) from the trench as the trench is cut. The trench may be backfilled using a flowable composition. In one example, the flowable composition rigidifies after being flowed into the trench, and thereafter is substantially impermeable (e.g., having a hydraulic permeability of less than 0.0000001 cm/s upon drying), non-compressible and/or non-expanding.
