Abstract

A waterproof membrane comprises a radial junction corrugation (24) disposed between two sectorial portions (22), each of the two sectorial portions having an angular deviation (E) between the radial direction (A) of the sectorial portion and a longitudinal direction (B) of the radial junction corrugation (24), wherein each of the two sectorial portions further comprises a truncated corner plate (40) having a radial corrugation portion extending in the radial direction of the sectorial portion at a distance from the first sides and joining the second sides of the truncated corner plate, said truncated corner plate having an inclined side extending from a first truncated side to a second truncated side, said inclined side having said angular deviation (E) with said first truncated side and being disposed at said edge of the sectorial portion parallel to the longitudinal direction (B).
