Hydromulch: The Easiest Method of Erosion Control

What is Hydromulch?

Hydromulching, which is sometimes also called hydroseeding or hydraulic mulch seeding, is a method of planting grass in which a mixture of water, fiber mulch, tackifier (an adhesive substance), and seeds are sprayed over an area to prevent soil erosion and promote re-vegetation. The mixture is applied to the area from a mounted tank and is sprayed through hoses to promote even application. You might think of Hydromulch as a liquified combination of mulch and grass that sticks to the ground and coats it so that erosion of soil is limited and new grass can grow. There are various seed types available for hydromulch application, so you can choose what is best for your area and needs.

What does Hydromulch do?

Hydromulch is a revegetation tool. This essentially means that it keeps soil in place and helps grass grow and flourish where there was little or none before. The mulch significantly limits moisture evaporation from the soil. Since grass seeds require moist ground in order to grow and develop, keeping in as much moisture as possible allows grass to grow quickly. The mulch also protects the soil from erosion. If erosion is prevented, the grass seeds are held in place, which ensures a more even lawn.

What are the benefits of Hydromulch?

Hydromulch is typically cheaper than laying traditional sod, especially if you are trying to cover a large area. Hydromulching allows for even application and the growth of grass after hydromulching is very fast and the seeding process is quick and efficient, so you would see results quickly. Areas that have been seeded with hydromulch tend to see full growth of new grass in about a month. At the end of the month, the grass would be so well established that it would even be ready to mow! It is especially beneficial around homes that are experiencing severe erosion, around construction sites, and on hillsides and sloping lawns where rainwater tends to wash away the soil.

Do I need Hydromulch for my commercial project?

Erosion control on a commercial job site can be one of the biggest headaches in construction. To help you avoid that headache, Hydromulching may be the quickest, most budget-friendly solution. Hydromulch will keep the soil in place and deter any erosion from happening so that your site remains intact. Since Hydromulch works best when seeding large areas, new construction, recently completed construction, and areas that have been burned or tilled for reconstruction tend to offer the best uses of hydromulch. If you have finished a project and want to make it look complete, you will find Hydromulch to be a cheaper and more efficient option for getting a finished look with lush green grass than you would if you seeded the area.
