PITCH FIBRE SYSTEMS

The Pitch Fibre Pipe Association present information relating to pitch fibre drainage systems. A general introduction includes a list of the advantages of the system. Technical data are given which are based on the various specifications for pitch fibre systems. They include sections dealing with theoretical design considerations with respect to narrow trenches, their application and practical considerations. Information is given on the use of different bedding materials including friable granular materials, cohesive soils and concrete. Details are also given of shallow depth installations, multiple pipe installations, the use of pipes near foundations and under buildings and application under particular ground conditions (including mining subsidence, waterlogged ground, wet peat and running sand). Jointing is next dealt with and access by means of manholes and rodding systems. Sub-surface drainage is discussed followed by leeching beds, hydraulic flow characteristics, chemical resistance and the use of pitch fibre electrical conduits. A list of relevant specifications is given. Leaflets are enclosed which give a general specification, a guide for installers of house drainage systems and a discussion of the main causes of drainpipe installation failure. /TRRL/
