Gdt Lining Systems have completed complex and detailed secondary containments involving the placement of lining system under and around steel storage tanks, which contain a variety of hazardous and hydrocarbon products. We have worked with jet fuel, diesel, caustic soda. The secondary containment pondage is designed to AS 1940. GDT can offer design and construct services for secondary containment systems or install only. We are more than happy to offer advice.
