The invention is concerned with damp-proof courses which can be used at the end of a cavity wall of a building structure adjacent to a door or window frame. The invention provides a damp-proof course, which has a high degree of versatility in use. The damp-proof course in accordance with the invention comprises a strip of corrosion-resistant moisture impermeable material (and is preferably formed as a plastics extrusion) and its cross-section provides two web-like elements arranged at an acute angle in the range 45 DEG to 90 DEG with respect to each other the first web having at least one undercut formation on the inside of the angle and the second web having at least one undercut formation on the outside, each of the undercut formations providing anchorage for wall ties at any position along the length of the strip, and at least one of the webs also has a moisture barrier formation on its inside extending throughout the length of the strip. |
