Most people don't think much about the foundation of their pool. A weak foundation can lead to high maintenance costs in the future.  Knowing this, Sharkline constructs its pools with quality materials that endure the harsh elements of nature. Oversized plates, made of Double-Coated Marine Quality Aluminum, yield 40% more support than other above-ground pool foundations. The result is a long lasting foundation that continuously stands up to heavy weight and corrosive soil conditions.
