Using Polyacrylamide (PAM) to Reduce Erosion on Construction
PAM is water soluble, but dissolves very slowly and requires rapid agitation and extended mixing time. Water with more than 0.1 percent dissolved PAM is often noticeably viscous, and most PAMs have a maximum concentration of 0.5 to 1 percent in water. A good rule of thumb is to mix 1 pound of PAM per 100 gallons of water.
