The production process as well as some critical properties of a new PVD, namely BRECODRAIN (patent applied for), are reported here in some detail. In order to view this development in proper perspective, comparisons are made with another drain made of natural fibresnamely FIBREDRAIN – and two commercial synthetic drains. The study puts the BRECODRAIN in a more favourable light vis-a-vis the FIBREDRAIN. However both these products compare poorly with synthetic PVDs barring probably in the ecological aspect and in sensitivity to deformation.
