We developed our dam liners to solve leaking and evaporation issues in dams and ponds. They are durable, reliable, and made to the specifications of the customer. Our dam liners come in thicknesses of 0.3 mm, 0.5 mm, 0.75 mm, and 1 mm. They come in widths that match the reservoir's or tank's size and form. They are UV-treated and black in color. The dam liner prices depend on their thickness.
