Marine and Civil Construction Services

Capability You Can Count On.

We deliver complex marine solutions and critical civil infrastructure with precision, reliability, and long-term value, even in the most challenging environments.

Marina, Jetties, Wharves, and Marine Construction

This is our primary area of expertise, having started the business in marina maintenance and construction over 20 years ago. Since then, Tas Marine has grown to deliver complex marine projects with precision and adaptability, supported by our extensive range of floating plant and specialised marine piling equipment.

With extensive experience across diverse environments, Tas Marine delivers projects ranging from marinas in urban bays and high-traffic waterfronts to some of the most exposed, remote and challenging locations. Known for our ability to adapt and excel in demanding conditions, we
have successfully navigated extreme challenges, including monsoonal weather on Christmas Island and the rugged coastal terrains of New Zealand’s South Island.

Our skilled workforce and state-of-the-art equipment enable us to overcome complex logistical and engineering obstacles, ensuring each project is delivered safely, efficiently, and to the highest quality and environmental standards.

By combining technical expertise with innovation, including pioneering hydraulic hammers and crane-based pile spinning techniques, we consistently exceed client expectations, setting benchmarks for excellence in marine and civil construction.

Our Capabilities Include:

Construction and maintenance of timber, steel, and concrete wharves, jetties, and marinas.
Installation of floating and rock-piled breakwaters.
Pile repairs and all aspects of marine piling.
Installation and maintenance of navigational aids and beacons.
Construction of durable boat ramps.
Precast and in-situ concrete wharf decks and structures.

Our ability to operate effectively in challenging environments, coupled with our
state-of-the-art equipment and skilled workforce, sets us apart as a trusted leader in marine construction.
