        In this study, the prefabricated lightweight plastic foundation which was made of recycled plastic for sewage pipeline was developed and PE triple flexible pipe was used to evaluate the fundamental characteristics of foundation for sewage pipeline. Two types of prefabricated plastic foundations were adopted. The basic properties of each plastic material were evaluated, such as density, elastic modulus, unconfined compressive strength, and bending stress. The allowable load at 5% of pipe deformation was 1.49 ton for 100% new plastics foundation, and 1.35 ton for composite plastic foundation. The use of fabricated lightweight plastic foundation shows 100% of higher load support than without foundation.
