The joint comprises a pair (12,14) of complementary engineering grade polymer injection mouldings. Each moulding is comprised of generally equal length oblique webs (15), set at 60° to a mid-plane (16) of the assembled joint, shorter, inner webs (17) and a longer, outer webs (18). Centrally of each outer web (18) is an aperture (21) and centrally of each inner web is a pin (22) with a step (23) and a pointed head (24). The heads of one moulding clip into the apertures of the other whilst the steps determine their separation gap (25). The trapezium wave shape of the joint provides re-entrants (31) from the plane of the outer webs (18) towards that of the inner webs. Outwards of the re-entrants extend anchoring formations (33). Behind each re-entrant these formations are joined by a tab (34). Supports (41) are provided to support the repair joint off the bottom of the cavity via the tabs (34). The supports are of lazy-Z shape, with threads (42) formed at both ends. At the tabs, bolts (43) through the tab apertures (35) and secure the supports to the tabs. Further bolts (44) are engaged in the distal ends of the supports and hold the supports and the joint off the bottom of the cavity.
