Installing a 4' x 50' AquaDam® in standing water. Notice how high up the bank the master tube starts compared to the height of the workers.  

Even in standing water, it is recommended that you maintain a sufficient head within the AquaDam® during the entire unrolling process. 

This installation took approximately 20 minutes using two 3" semi-trash pumps for inflation. Always keep a greater head inside the AquaDam® than that of the outside water. Take one step at a time and do not hurry. Do not take the surrounding water for granted.

This is a good position to hold back the water pressure inside the AquaDam® that pushes on the legs of the workers.
