Testing Hydromulch Materials in the Lab at Montana State University

This video shows Andrew Durado of Montana State University preparing hydromulch samples in the lab for testing. The materials in this sample include cellulosic material, tackifier, and water. The materials are combined in a bucket and then blended until a smooth slurry is obtained. This slurry is poured over a screen to drain excess water and then dried to obtain a uniform mulch sample. The mulch samples are then evaluated for various properties such as density, puncture resistance, tensile strength, porosity, and rain fastness to determine the most affective mulch formulation.
