A variety of sheet pile structures are widely used in hydraulic engineering, transport, industrial, and civil engineering. These structures are load-bearing structures in the form of a solid vertical or inclined wall. This structure is formed by sheet piles embedded in the ground. The piles are connected to each other using tongue and groove locks. Metal sheet piles are most often used for these purposes. However, they are susceptible to corrosion over long periods of use. Currently, sheet piles made from polymer composite materials (PCM) have become widely used. Such PCMs have cross-sections of various geometric shapes. Of particular interest are composite sheet piles based on polyure-thanes filled with fiberglass. This article examines the performance characteristics of pultruded composite sheet piles with a polyurethane matrix of the CShP-150UM brand. The data on the influence of ambient temperature, ultraviolet radiation and the chemical nature of aggressive environments on the strength of polymer composite sheet piles of the CShP-150UM brand are presented. It has been shown that polyure-thane sheet piles have high strength characteristics and are resistant to various aggressive environments and ultraviolet radiation. The data on creep of composite sheet piles of the CShP-150UM brand at a relative stress level from 0.21 to 0.95 σbend during their testing for 3,000 hours are presented. Polymer composite sheet piles with a polyurethane matrix of the CShP-150UM brand are recommended for wide use in the construction industry
