Our precast concrete spill/leak containment vessels are constructed in accordance with Section 501, “Concrete Masonry”, of the Standard Specifications for Road and Bridge Construction, State of Wisconsin Department of Transportation.
The concrete is air-entrained and has a minimum of 4000 PSI compressive strength when delivered. Compressive strengths of over 7000 PSI are common in our vessels after 30 days. The reinforcing steel is grade 40, No. 4 bars on 12″ centers each way. The reinforcing is designed for the dynamic forces that exist when transporting the units. These forces exceed those experienced on the site.
Anchor bolts are furnished to tie down the petroleum storage tanks. No additional clearance for collision protection is required provided the tank is centered in the vessel and firmly bolted to the vessel. These anchor bolts will prevent the floatation of any empty tank by rain water.
