Hydraulic Mulches and Tackifiers

Hydraulic erosion control products are mulches and glue-like substances that are sprayed with water onto the soil surface. 

HECP Applicator Certification

MnDOT co-sponsors a certification class for contractors who will be applying hydraulic erosion control products (HECP).  This normally occurs every three years, but due to the COVID-19 pandemic the 2020 session was cancelled and current certifications have been extended.  Open the following document for more information.


Requirements for Hydraulic Mulches and Tackifiers are found in the MnDOT Standard Specifications for Construction, available on the MnDOT Spec Book web page. Open the document and search for the following:

  • Installation requirements: 2575 Establishing Turf and Controlling Erosion (See 2575.3 E Placing Hydraulic Erosion Control Products)
  • Material Requirements: 3884 Hydraulic Erosion Control Products
