They are manufactured of fiberglass in a single piece with no joints or seams, using a closed-molded process that provides a superior structure, eliminates any chance of leaks and offers an aesthetically pleasing exterior. They are also easy to ship and set. They are available up to 12 feet tall, 20 feet wide and 40 feet long, with custom sizes also available. Interior surfaces are coated with a polyester gelcoat, while exterior surfaces are protected with a high-performance polyaspartic urethane.
