J₂ Engineering provides a full range of analysis, investigation and testing in the area of slip, trip and fall accidents. Our investigation includes an evaluation of the shoe sole material along with the scene testing to determine the slip resistance of materials and walkway surfaces under differing conditions. We use only ASTM approved test equipment and procedures. We also work with major shoe manufacturers in the development testing and analysis of shoe soling materials. J₂ Engineering is also involved in state of the art research and the development of national standards for the analysis of slip resistance.
