Formulations of Posi-Shell® can be created to provide varying degrees of long term erosion control.  By simply increasing the amount of gauging material and decreasing the coverage area (which results in a thicker application), erosion control coatings can function in place for up to several years.  Similarly, by decreasing the amount of gauging material and increasing cover area short term control such as dust control can be applied easily and economically.

As shown in the photos from a Polynesian Island, Posi-Shell is ideal for extreme erosion control applications such as these nearly vertical slopes.  Also shown is a shooting range in Arizona- again nearly vertical slopes have been covered.   Because of the highly adhesive qualities of Posi-Shell it will adhere to any surface at any angle, even an overhang.

Posi-Shell is fast becoming a valuable erosion control tool in non-landfill related industries such as public works, police firing ranges (see photo), departments of transportation, highway work, or chemical facilities.

There are erosion control applications for which the “right answer” is to establish vegetation.  Sometimes the answer is a roll out membrane, but there are times when neither of these is ideal or even a possibility and yet erosion control is still required. 

Posi-Shell ingredients can be used as hydroseeding medium,  This is extremely beneficial on very steep slopes as shown, or in areas or at times when it is not known how long it will take for seed to germinate.  Posi-Shell will hold the soil in place while waiting for the right conditions to grow grass.

In situations where Posi-Shell has been used for long term cover it is easily worked into the soil by tracking across it with heavy equipment – essentially pulverizing the Posi-Shell which then mixes with the soils.  Posi-Shell has no negative impact on the growing conditions.
