Panhandle Concrete Products' precast box culverts will reduce construction time. This, in turn, reduces road/lane closure time and detour time. All these factors add up to reduce costs to the Contractor and lower the final project cost to the Owner.
All boxes are designed and engineered to your specific loading requirements and fill depths. These boxes will meet ASTM and AASHTO standards. All boxes are constructed of a 7,000 psi (28 days) concrete mix. This mix has a one day strength of 3,000 psi. The seven-day strength is 5,000 psi. Each box undergoes a strict Quality Control Inspection. These include Pre and Post Pour Inspections, Dimension Check, Reinforcement Check, Joint Test Fitting, and Concrete Testing.
