GRAF Carat S Belowground Tanks
The Carat S is a unique plastic tank line that is manufactured to consistent, tight tolerances resulting in a product that is of the highest quality, strength, reliability and versatility. Unlike other below ground plastic tank lines, the Carat tank wall thickness is equal all around and is made from DuralenĀ®, a high-quality food grade polypropylene material that is extremely rigid and impact resistant, therefore ideally suited for producing underground tanks. Carat S Tanks carry a 15 year manufacturers warranty against defect and DuralenĀ® can be easily recycled which reduces waste and its impact on the environment. The Carat S tank line can be outfitted with packaged rainwater and wastewater systems, easily installed before or after delivery to site. It is not suited for potable water.
