Using Polyacrylamide (PAM) to Reduce Erosion on Construction
Therefore, erosion control should always begin with protecting the soil from rain droplets and slowing overland flow by using mulch and vegetation. PAM does not directly protect soil from rain droplet impacts, but it reduces soil detachment, maintains the soil’s structure, and increases infiltration rates early in the rain event.
