A Flexible and Reliable Solution for Temporary Containment

Lightweight, cost-effective and easy to deploy, TRFLEX® flexible liners (ECO, ECO+, SUPER-ECO) provide an ideal temporary containment solution for sites with difficult access or maintenance works. The reinforced TRFLEX®-REFOR version, equipped with a high-resistance tubular structure, is designed for the most demanding conditions and also enables long-term storage of transformers filled with dielectric oil. Manufactured from waterproof and durable materials, all liners ensure effective dielectric protection while simplifying logistics.

Safe Storage of Oils and Hydrocarbons

TRFLEX® basins provide temporary containment of dielectric oils and hydrocarbons while preventing any soil or water pollution. They are designed to withstand chemical exposure, harsh weather conditions and high mechanical stresses.

Fast Installation, Even in Emergency Conditions

Thanks to their lightweight and foldable design, TRFLEX® basins can be deployed within minutes. Their ease of transport and installation makes them an ideal solution for emergency interventions, maintenance operations and remote job sites.

Flexible Storage Bunds and TRFLEX® Solutions

TRFLEX® Standard, ECO, ECO+: A Flexible Transformer Bund for Every Need

The Standard, ECO and ECO+ models offer an excellent strength-to-weight ratio for temporary transformer oil containment. They are manufactured from high-tenacity double-weave polyester fabric, ensuring long-term watertight performance as a portable oil containment berm. Their reinforced structure makes them a reliable and extremely fast-to-install flexible oil retention system.

TRFLEX® ECO-MAINTENANCE & ECO-TRUCK™: Mobile Oil Spill Containment Berm

The TRFLEX® ECO-MAINTENANCE model is ideal for transformer maintenance containment, integrating anti-slip gratings to secure pedestrian traffic. For heavy vehicle access, the TRFLEX® ECO-TRUCK™ acts as a reinforced mobile oil spill containment berm, supporting traffic without risking perforation.

TRFLEX® REFOR: Flexible Retention Bunds for Transformer Storage

Designed for harsh environments and long-term temporary oil storage bund needs, TRFLEX® REFOR features a double-reinforced tubular structure for optimal mechanical strength.


Key Technical Features

Waterproof Flexible Tank Technology

TRFLEX® basins are manufactured from high-performance technical fabrics with a hydrocarbon-resistant vinyl coating to provide double waterproof protection. This waterproof flexible tank design includes UV protection to extend service life in outdoor environments.

Double-Sided Welding and Quality Control

Each model is assembled using high-frequency welding, ensuring a temporary retention bund with complete watertight integrity. We use robust fabrics with high resistance to tearing and puncture, making them suitable as a construction site hydrocarbon retention bund.

Emergency Spill Containment and Accessories

Transport and Storage Options

We provide foldable flexible retention bunds for transport, which can be easily stored in transport bags or rigid cases to optimize on-site logistics. These systems are perfectly suited for emergency spill containment where responsiveness is critical.

Filtration and Drainage

TRFLEX® basins are compatible with SPI drainage systems for clean rainwater discharge. This ensures autonomous drainage of these flexible retention bunds for transformer storage without risk of soil contamination.
