In application of hard and impermeable polyvinyl compounds for sand dune stabilization there is two opposite concerns for selecting the best stabilizing compound: They are very hard and prevailing compound against wind erosion?, On the other hand, they are impermeable for water and might be sensitive for water erosion and producing runoff? Do you have any idea for making decision which aspect of these compounds is preferred in selection the best compound? Hardness or impermeability?
The best regards and thanks for your responses

The critical factor is correct moisture content of the polymer for most efficient compaction. Physical strength can be lost when wet, so some permeability is required too. I think a balance between those two factors is required.
We find microbial polymer ( Xanthan, Curdlan, Pollulan etc.) are very efficient in sand dune stabilization. However, it was also noticed that Polyvinyl acetate and Poly methyl & Poly methacrylate also very effective. Moisture content and permeability also very important factor for selecting the polymers.
The information on the following link may help you including Xanthan, Curdlan, Pollulan etc
