The prefabricated concrete component (1) has an L-shaped cross section with a horizontal member (2) designed to be laid directly on the ground, and a vertical member (3) designed to cover the gap along the bottom of a mesh fence. One end of the component can be stepped (4, 5) to engage with a matching end on an adjoining one. The height of the vertical member is not great, e.g. 10 - 20 cm, but is sufficient to dissuade animals such as dogs, from squeezing under a mesh fence to get in (or out).
