A shuttering support and related system

The present invention provides a support and a system for bracing and supporting the sides of trenches, excavations or embankments. The system comprises a plurality of elongate plank elements and at least one main shuttering support. Each main shuttering support has an inner wall arranged in use to extend substantially vertically, and a ground pinning element extending from a rear face of the inner wall which is arranged in use to extend substantially horizontally and remain in contact with the ground. A front face of the inner wall defines a plurality of vertically aligned slots. Each slot is shaped and dimensioned to receive the elongate plank element. The system further comprises an elongate upper side brace and an elongate lower side brace, said side braces comprising a connection mechanism for engaging each side brace and at least two plank elements, so that in use, the side braces are aligned to extend substantially horizontally and with the inner wall, one side brace extending above the other side brace.
