Results of deformation measurements carried out on buried plastics pipes installed at six different tests sites are discussed in this paper. The results show that the deflection of buried pipes is usually rather small and the time dependence is limited to a few years after installation. Traffic loading does not result in extra deformation. The results can be largely explained by consolidation processes of the soil surrounding the pipe. The quality of installation proved to be the most important parameter affecting the deformation of buried plastics pipes.
