HDPE pipe is strong, durable, flexible and light weight. When fused together, HDPE has a zero leak rate because the fusion process creates a monolithic HDPE system. HDPE pipe is also a more environmentally sustainable option as it is non-toxic, corrosion- and chemical-resistant, has a long design life, and is ideal for trenchless installation methods because of its flexibility.
