The emergence of flocculants has made a significant contribution to the site manager’s toolbox. Fundamentally, polymers or flocculants bind soil particles together. The technology has provided answers to some of the most challenging site stabilization issues. Available in both granular and liquid form, flocculants can assist with vegetation establishment by binding seed, soil, fertilizer and mulch together. The products can also help with removing sediment from turbid stormwater runoff, and for dust control and more.
