THE TRAMMEL DRAINAGE SYSTEM

The economics and technical performance of drainage systems has become a critical feature of long-term soil drainage. Poor drainage can lead to heavy consequential costs due to environmental damage from waste pollutants. Such factors have led to the development of the trammel drainage system. The drain features a water catchment surface in the form of a laminated fibre fin which can be installed at any angle in the ground. The permeable laminate surrounds a perforated pipe at the base of the fin, so ensuring that subsurface water can pass from the laminate core into the pipe. Tests have shown that the core can retain permeability with lateral pressures as high as 600 kn/sq M. A number of applications of the trammel drain are discussed such as a replacement for an existing French drain, for the control of leachates, and adjacent to structures. (TRRL)
