Terra-Control® is our biodegradable soil binder and dust suppressant. TerraCONTROL is used as a tackifier and binder in most hydroseeding fibre mulch systems, either alone or in combination with other lubricants or soil ameliorants. TerraCONTROL is designed to penetrate and bind most ‘open’ soil types and sand, by producing a three dimensional ‘honeycomb’ matrix throughout the topsoil layer.
