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.
