Underground tanks carry a higher risk profile than any other storage solution. A leak doesn't just mean product loss — it means soil contamination, regulatory penalties, and potential site remediation costs that can run into millions of pesos.

​

Siegen UGTs are precision-fabricated double-wall steel tanks with built-in structural redundancy. The outer wall serves as a secondary containment barrier, capturing any leak from the primary vessel before it reaches the environment. Combined with our corrosion-resistant coatings and rigorous pressure testing, Siegen UGTs are engineered to protect your site for decades.

Key Engineering Features:

​

• Double-wall construction — primary + secondary containment

• Superior structural strength for underground soil pressure

• Compatible with petroleum products, diesel, gasoline, and hazardous liquids

•  Horizontal and vertical orientations available

•  Corrosion-resistant coatings for long underground service life

•  Trusted by gasoline station operators, fuel depots, and industrial sites
