Most of our outdoor stone fountains are made of cast stone. Cast Stone Fountains are made of concrete which is poured into a mold and often aims to resemble natural stone. Cast stone weathers well in all climates except during the winter months. Cast stone fountains are highly susceptible to cracking in the cold weather if not properly insulated and covered. These fountains come in many different finishes according to their brand. Using fine high quality aggregate for the cast stone creates smooth even surfaces. Cast stone fountains come in many different styles including tiered and contemporary.
