Convault above ground fuel tanks info
primary & secondary tanks
The primary steel tank is fabricated then is wrapped with a secondary containment before it is finally encased with a six-inch reinforced concrete vault.
The secondary containment provides spill containment and is made from a high performance, 30 MIL high density polyethylene membrane that encloses the primary tank.
Therefore, the Convault® tank provides you a secondary containment equivalent to a double wall steel tank plus protection of six-inch reinforced concrete. For more info.
concrete tanks built to last
-
Rust Resistant.
The primary steel tank is isolated from the concrete encasement to prevent corrosion. In addition the concrete creates a barrier to environmental elements like rain and salt. This provides decades of rust resistant primary tank service. For more benefits.
-
Fire Protection.
The seamless six-inches of reinforced concrete provides a two-hour fire protection. In addition the monolithic concrete vault and insulation provide thermal protection from the environment. For more benefits.
-
Impact Resistant.
The six-inches of reinforced concrete protects the primary steel tank from vehicle impact and is blast resistant. During testing Convault tanks withstood the vapor cloud blast, a 50 lb TNT blast centered at 5 feet from the tank, and a 500 lb TNT blast centered at 20 feet from the tank.
