The multi-directional expansion joint for civil engineering projects e.g. roads, runways, etc., comprises rows of load bearing elements which are aligned, and spaced apart. A section rests on the load elements, and forms a support for a removable separating strip, used during the casting of the blocks constituting the road surface etc. The separating strip also acts as a guide for a vibrating beam which is used to tamp the concrete down. - When the blocks have dried, the strips are removed leaving grooves between adjacent blocks which are subsequently filled with elastics material. The profile is pref. an inverted T-shape in cross-section.(0/9)
