Albarrie’s transformer secondary oil containment systems and oil spill containments use patented mineral oil-reactive self-sealing smart fabric technology, providing a virtually maintenance-free containment.


Chronic transformer oil spills and leaks are a significant problem for electric power substation transformers. Aging equipment is usually the cause, which costs companies thousands of dollars in cleanup, penalties, outages, and emergency maintenance. In addition, transformer oil spills redirect the work efforts of critical staff needed in other operating areas and hurt your reputation.

Governments worldwide have passed environmental regulations to ensure organizations take responsibility for protecting our environment and lessen the effects of climate change. These regulations push utility companies to address aging oil-filled equipment polluting our environment. The EPA Spill Prevention Control and Countermeasures (SPCC) per 40 CFR 112.7, IEEE Std. 980, and MOECC requirements in Canada require organizations with oil-filled equipment to have an oil spill response plan or a secondary oil containment system to prevent an oil discharge from reaching navigable waters, protecting wildlife and public safety.

SorbWeb™ Plus Transformer Secondary Oil Containment System uses smart fabric technology. The fabric allows rainwater and snow melt to pass through, while providing continuous protection against oil spills and leaks around mineral oil-filled equipment such as substation transformers. The innovative fabric and containment design proactively protects the environment around oil-filled equipment.

Product Details

Albarrie's Sorbweb Secondary Oil Containment Systems for Transformers Detail

Albarrie’s transformer secondary oil containment systems and oil-spill containments use patented mineral oil-reactive self-sealing smart fabric technology known as Oilmat. The smart fabric contains a unique proprietary blend of dense oil-immobilizing polymers, called Alabsorb, needle-punched between two nonwoven fabric layers that seal on contact with oil, not water.

In a passive state, Albarrie’s Transformer Secondary Oil Containment System allows water to pass freely through the Oilmat without collection. The Oilmat is installed on the containment floor. When the oil comes in contact the Oilmat, it undergoes a chemical change. This chemical change congeals and seals the oil inside the fabric, turning the fabric into an impassable membrane, preventing environmental pollution.

We know that substation transformers frequently have small leaks. That’s why we’ve designed our transformer oil containment system with SAM™ (SUPER ABOSOBSENT MAT). Once the Oilmat is positioned and bonded, SAM™ is installed throughout the containment area. It offers an exceptional absorption capability per square inch to prevent small leaks from reaching the Oilmat and sealing the containment. SAM™ absorbs and locks in oil but remains porous, allowing water to pass through.

Our systems are installed without interruption of service in either brownfield or greenfield applications. They come complete with all materials required for assembly. They can be installed by your organization or your preferred contractor under Albarrie’s guidance or by our professional services team.


All our transformer secondary oil containment systems are designed to allow for drivability, allowing your vehicles to access the transformer without harming the containment.


Traditional concrete secondary oil containment systems aren’t ideal for severe weather, such as heavy rainfall, snow, ice, and freezing temperatures. There’s a high risk of water overflowing and mechanical pumps failing. Fortunately, due to the free-draining ability of Albarrie’s smart fabric, you never need to worry about severe weather.


Albarrie ensures your project is successful and goals are achieved through a consultative process. Our standard design includes:

  • Earthen berm design without a wick drain.
  • Site plan drawing for 110% containment volume + a 1/25 rainfall event
  • A civil materials takeoff list
  • IEEE guidelines for secondary oil containment
  • SPCC Rules/MOE Requirements
  • Site and soil considerations with a client-provided geotechnical report.
  • Client specifications
