ABSTRACT:
Drainage foils are described in two parts, a first part including the drainage surface and means for mounting the foil on a support, and the second part including the land surface and the leading edge. The second part is fitted with wear-resistant material, and is removably fitted to the first part, so that the two parts can be interchanged to facilitate changing foiling angles and land surfaces in a given installation.
