Pond for a Polar Bear in the ZOO of Sydney, Australia was made with KF-A admixture to the

Shotcrete Mix which provided reliable structure for cold and salted water. There are no leaks 

after 14 years. As usual, any other materials and devices barely lasted one year.  
Fish pond in Gilroy, California, was built with KF-A added to the shotcrete, 

but just one batch was applied without KF-A.
