A spacer 10 for a reinforcement cage used in constructing diaphragm walls, shafts and piles comprises a planar bearing panel 20 having upper and lower edge portions 22, 24. At least two legs 30 depend from each of the edge portions, the legs being laterally spaced and splayed out with respect to the bearing panel. Each leg comprises a pattern of holes 50 spaced apart in a direction perpendicular to the bearing panel, allowing the spacer to be attached to the cage at a predetermined, adjustable distance and orientation from it. The edge portions may be curved or angled. A rod may be provided for passing through corresponding holes. A cross strut may be provided between at least one pair of opposing legs. At least one inner leg having a pattern of holes may be provided depending from the panel. The bearing panel or one or more of the legs may be formed from a sacrificial material such as GFRP.
