Prestressed Concrete Storage Tanks: Re-Engineering Storage.

Preload International, a member of the CASHMAN Family of Companies, has been pioneering the research, development, design, and construction of prestressed, precast, sliding base concrete tanks for over half a century.

Preload’s prestressed concrete tanks provide the durability, flexibility, and safety to store today's refrigerated and cryogenic liquids, such as LNG, liquid oxygen, liquefied petroleum gas, ethylene, ammonia, and others, for a wide range of storage volumes—from 5,000 to 300,000 cubic meters. Preload’s tank solutions also address the need for high-quality water storage internationally along with emerging thermal energy storage (TES) technology that has resulted from efforts to focus on energy-efficient and environmentally responsible solutions. Several factors—economic growth, infrastructure expansion, and a high demand for centralized cooling—are increasing the need for high-quality water storage throughout the world. Recognizing this opportunity, Preload International has become involved in several large-scale water storage projects in the Middle East and elsewhere.

From potable water to wastewater and TES to industrial applications including the storage of liquids at cryogenic temperatures, you can rely on Preload International's engineering and construction expertise to develop the perfect solution for your storage challenge.
