At Intercoastal Marine, we bring extensive experience and precision to every civil and transportation project we undertake. Our team has worked on a wide range of infrastructure developments, from DOT and municipal bridges to complex culvert installations. We understand that these projects form the backbone of communities—supporting travel, commerce, and safety—and we take that responsibility seriously. Whether we’re building a new bridge or rehabilitating an existing structure, we focus on quality craftsmanship, durability, and compliance with all state and federal standards to ensure every project stands the test of time.

Our capabilities also include dam construction, repair, and maintenance, where precision engineering and safety are paramount. We work closely with engineers, environmental agencies, and local authorities to ensure each dam project meets structural integrity requirements and environmental regulations. From spillway improvements to embankment stabilization, our team brings the technical skill and field experience needed to handle challenging water management and containment projects. We take pride in our ability to deliver dependable solutions that protect communities and ecosystems while ensuring long-term reliability.

In addition, we specialize in deep foundation and soil enhancement services that provide critical support for a wide range of structures. Our work includes pile driving, helical pier assemblies, micro-piles, and tie-back systems—each tailored to meet specific site and load requirements. These systems form the foundation of stable, long-lasting infrastructure, and we bring the equipment, expertise, and attention to detail required to execute them safely and efficiently. At Intercoastal Marine, we view every civil and transportation project as an opportunity to strengthen the communities we serve, building infrastructure that supports progress today and well into the future.
