Specialty Precast

IECS Continues to set the bar in the world of specialty precast challenges, offering segmental systems for most structural designs. Pre-casting the typical “cast-in-place” specification is a solution that can save the construction world time and money by greatly reducing shoring, dewatering and weather variables. All IECS’ products are manufactured indoors under a controlled environment ensuring the quality out company has been built on for over three decades. Continuing to reinvent what precast can be IECS welcomes all challenges, big or small and have shown time and again the ability to think “outside the box” and manufacture to site specific needs and obstacles.
