Teranap Bituminous Geomembrane (BGM)

Heavy-Duty Waterproofing. Built for Harsh Realities.

When performance under pressure is critical, this Bituminous Geomembrane (BGM) delivers. Designed for long-term sealing, erosion control, and water containment in the toughest environments, our BGM liner offers exceptional durability, flexibility, and adhesion to varied subgrades. It’s your go-to solution for infrastructure that must last, no matter the terrain, climate, or challenge.

Engineered for the Toughest Jobs

Our BGM liner is a reinforced waterproofing membrane made from elastomeric bitumen, offering superior mechanical protection, long-term watertight performance, and resistance to environmental stressors. It adheres well to surfaces like concrete, clay, and compacted soils, making it ideal for a wide variety of complex infrastructure projects.

Applications in Critical Infrastructure & Environmental Projects.

This BGM is trusted across high-value projects in:

Dams and flood retention basins
Irrigation and potable water reservoirs
Landfills, capping systems, and tailings dams
Tunnel and culvert waterproofing
Mining and industrial containment
Stormwater harvesting and drainage basins

Trusted by Government, Civil, and Industrial Experts

State & Local Authorities – Water infrastructure, flood control, and stormwater management.
Mining & Resource Companies – Tailings containment and dam sealing.
Engineering & Civil Contractors – Tunnel waterproofing and multi-layer barrier systems.
Environmental Planners & Consultants – Erosion and seepage control for high-risk zones.

Key Benefits

1. Superior Puncture & Impact Resistance

Unlike traditional plastic liners, BGM resists mechanical damage from sharp rocks and settlement movement, ideal for challenging terrains and exposed conditions.

2. High Flexibility & Conformability

Maintains watertight integrity even when placed over irregular surfaces or subject to differential settlement and vibration.

3. Long-Term UV & Weathering Performance

Naturally UV-resistant with built-in ageing stability, BGM performs under extreme sun, wind, and water exposure, making it ideal for Australian and Pacific climates.

4. Strong Surface Bonding

Adheres effectively to concrete, metal, and soil, reducing risk of underflow or migration, suitable for complex construction zones.

5. Low Maintenance, Long Life

Designed for decades of in-service performance with minimal upkeep, saving costs over the long term.
