A method of forming a joint (2) and the member (8, 28) used therein between two cementitious faces (3, 4) in which the space between the faces is not of uniform cross-section, but has at least two different widths (5, 6) and is stepped with a shoulder (7). The joint member has a central upright portion (9), a lower portion or head (10) for positioning the member relative to the lower faces (5). The lower portion includes one or more sets of projections (14) which are resiliently deformable. Flanges 11 on either side of the central portion have limited movement relative to the central portion rest on the shoulder (7) of the faces when the space between the member and the faces 3, 4 is filled with a resilient but compressible product.
