TerrAffix-Hydramulch is a hydraulically applied erosion control product that protects slopes better than standard hydroseeding against soil and seed loss from heavy rain and wind from day one of application. It is 100% natural, consisting of reclaimed materials.
Tackifiers and polymers within the TerrAffix-Hydramulch matrix chemically bond the soil particles preventing any soil loss even during major storm events. The all natural recycled natural eco-fibre blend of TerrAffix-Hydramulch holds just the right amount of moisture so is far quicker than standard hydroseeding to quickly establish germination and promote vegetation growth for permanent erosion control.
TerrAffix-Hydramulch offers exceptional, high-performance slope erosion control equivalent to a biodegradable blanket coir or straw blanket.
TerrAffix-Hydramulch can be installed over rough terrain where voids, tree roots, rock outcrops and existing vegetation may be present. In contrast, geotextiles need good ground preparation.
This system is better than standard hydroseeding, being 99.6% effective in reduction of soil erosion under extreme rainfall in independent large-scale slope testing and has faster seed establishment than any other method. The proprietary blend of natural and recycled adds significant amounts of nitrogen, phosphorous, organic content and potassium to the soil.
TerrAffix-Hydramulch can be used to reduce topsoil depth and can remove the need for topsoil altogether if used in conjunction with TerrAffix-Hydrasoil
There are also significant Health and Safety benefits, reducing the need to access slopes as opposed to installing erosion control geotextiles/blankets.
