Patterson-UTI is an oilfield manufacturing company with a 1.4-million-square-feet facility on 29 acres in Houston. Rollcon was chosen as the right contractor for the job because we had the capability to replace all of the paving necessary without ever shutting down the manufacturing facility or disrupting its operations. Rollcon provided 1 million square feet of 14” dual-left roller compacted concrete as well as 140,000 square feet of RCC for employee parking. The work was executed over three phases, allowing the facility to remain operational throughout. RCC was chosen due to its long life and durability under heavy loads. The paving we provided hardened to a compressive strength of 5,000 psi at 28 days.
