Abstract: A drainage member for use in promoting the drainage of water away from a substrate positioned adjacent the drainage member which includes an elongated, longitudinally extending base formed of a flexible material and having a plurality of outwardly extending projections. The projections are spaced from one another to form drainage channels between the projections. The elongated base has a plurality of expansion zones formed of the flexible material and extending generally transversely of the longitudinal extent thereof, the expansion zones comprising a deformation of the flexible material that absorbs longitudinal expansion of such material when it is exposed to heat without any significant increase in the longitudinal length of the drainage member.

Abstract: A universal drain fitting for use with prefabricated drains of all sizes for joining the drain and a cylindrical-shaped pipe for making the transition between a drain and a drain outlet or between two drains in a drainage system. In the first and second preferred embodiments, the universal drain fitting includes a drain fitting portion formed by two walls in spaced parallel relationship with one another to define an open cavity and a pipe fitting portion connected to the drain fitting portion which includes a hollow cylindrical section with an opening adapted to be connected to a pipe. The open cavity has a plurality of sides formed by the space between the walls and includes at least two open sides adjacent to and in communication with one another for receiving a portion of a drain into the open cavity.
