Description:
The Kelp Tank at the California Science Center is an 188,000 gallon (712,000 liters) tank with sharks, moray eels, rays, rockfish and spiny lobsters (and over1,500 other fish ) where kelp algae grows as large as trees.  The Kelp Tank design combines a concrete structure with acrylic viewing panels and a 24-foot walk through tube at the bottom of the tank – and a wave machine that simulates natural ocean movement.  This piston also generates considerable water forces on the entire structure making waterproofing of the structure extremely important.

Products Used:
To meet the demands of this aquarium, PENETRON and PENECRETE MORTAR were used on the inside of the Kelp Tank to ensure total waterproofing of the entire concrete water containment structure.
