Industrial ponds are usually simple squares or rectangles with uniform, straight slopes.

Polyethylene Low-Density Linear (LLDPE)
For $80\%$ of landscape and golf course lake projects, I strongly recommend LLDPE. It is softer, far more pliable, and stretches significantly better than rigid alternatives. This flexibility allows the installation crew to mold the plastic tightly around decorative boulders, concrete fountain pedestals, and meandering shorelines without stressing the material. We typically supply LLDPE in 1.0mm (mil 40) zuwa 1.5mm (mil 60) kauri, wanda daidai daidaita kariyar huda tare da elasticity da ake buƙata.
