MnDOT has approved products for blanket and hydromulches. There are many versions of each type of temporary erosion prevention materials, that vary in thickness, composition, and cost.

The two most common stabilization methods to control erosion and establish vegetation used by MnDOT are Hydraulic Erosion Control Products (HECP) and Rolled Erosion Prevention Products (REPP). Specifying the best fitting product for the situation keeps MnDOT in compliance with stormwater permits and is more cost effective.
