Custom Structures

From massive 125,000 lb. slabs to intricately cast pedestals, Gainey’s loves to do CUSTOM precast!  If a project calls for cast-in-place, the odds are we can redesign it around precast.  Our technical sales team can review a set of plans and let you know if it would be a good application for PRECAST in the same day and typically within an hour!

Why Choose PRECAST?

  • Reduced site disruption and downtime
  • NO weather delays! Your pieces are waiting to ship when you pull the trigger
  • Increased corrosion resistance and durability
  • Increased strength – over 7500PSI in compression!


Example: Methanex SBR Tanks

“When the Methanex Chemical Plant needed to expand its facility and treatment capability, it was met with some unique challenges due to the rapid turnaround time they required to reduce downtime. Coastal Process contacted Gainey’s to supply massive precast tanks to take the place of the specified cast-in-place concrete sewer tanks. The precast tanks were delivered and set in only two days’ time by the Lemoine Company contractors, making this treatment plant the fastest installation that Methanex has witnessed for a system this size. Thanks to Coastal Process, their wastewater will be treated to the highest standard ensuring decades of compliance!”

We have a great precast plant...

Here is one of several multi-piece tanks being dry fitted and water tested prior to field installation. We now build above ground sewer treatment systems that can handle the hydraulic loads of above ground installation
