BGM Liners
Bituminous geomembrane, known as BGM liner, is a specialty geomembrane with composite layers that make it stronger, more watertight and more durable than resin based geomembranes. Its layers consists of an anti-root film with a glass mat providing high tensile strength; a non-woven geotextile that provides mechanical resistance to punctures and tears; and finally a specially designed elastomeric or blown bituminous binder provides waterproofing and chemical resistance. On the top surface, an applied “sanding” provides greater friction with overlaying soils contributing to better stability.
Bituminous geomembrane or BGM liner is used in civil infrastructure construction projects, hydraulic applications, and environmental protection applications. Because BGM liner is flexible it can adapt to any ground contour and absorb differential settlement. It can also support ballast, hot asphalt mix, and many other materials without special protection. Additionally, BGM liner can be used in conjunction with concrete, gabions or rocks.
This material has a long watertightness life and effectively resists leaching of contaminants, making it an ideal solution for waste containment.
