Flat line is now becoming the fastest selling product in the Zline Bunker Systems collection. This product is a unique, patent-pending material that is equipped with the same quality and value as all our premium liner products.

Flat Line is designed to provide superior bunker floor protection. It is commonly used alone on bunkers with flat bottoms and mild slopes. It does not have the sand retention capabilities as our other offerings, so use on steep long slopes would not be recommended as a stand alone system.

This material is solid and non permeable with proprietary coating used to create an incredible strong long lasting product. For comparable materials in this price range, no other liner offers the same level of protection or dollar for dollar value.
