Recreational facilities and transportation hubs built on a floating foundation.

How it works

How concrete pontoons are built and used

The strength of reinforced concrete and the buoyancy of a cellular plastic core, combined into a floating platform.

A close view of Vikingegaarden concrete pontoons shows the grey concrete, timber fender rail, steel cleat and end connection.

Each pontoon has a reinforced concrete shell around a cellular plastic core, providing buoyancy without a sealed air chamber. The pontoons are made in various sizes, shapes and configurations and are used as the foundation for docks, marinas, floating bridges and breakwaters.

Vikingegaarden helps you plan the layout, the sizes and the anchoring for the site, and delivers pontoons that fit the water levels, tides and weather it must handle.

Ecosystem

Concrete pontoons in a connected marina

A pontoon is the foundation. Vikingegaarden also delivers what goes on top of it.

Vikingegaarden plans and delivers concrete pontoons as part of complete floating structures: piers, bridges, breakwaters and swim docks. On the same pontoons we install our own marina equipment, such as Marinella service pedestals for power and water, lighting and access control, with connected service equipment managed on the Emiko platform. One supplier for the floating structure and the services on it keeps the project simple and the interfaces clean.

  • Service pedestals, lighting and access control mounted on the same pontoons
  • Connected service equipment managed on the Emiko platform
  • One supplier for structure and services
Vikingegaarden concrete pontoons support an integrated marina layout with a gangway, service posts, cleats and finger piers.

Product guide

Floating concrete pontoons for marinas, piers and breakwaters

Choose concrete pontoons around the intended use, water conditions, loads and service equipment. The structure and its mooring are designed together.

Applications for concrete pontoons

Concrete pontoons are used for marina and harbor piers, floating bridges, walkways and recreational platforms. The reinforced shell and cellular core provide a floating structure that follows changes in water level.

Each application sets different requirements for loading, stability and mooring. For an exposed location requiring wave protection, assess a floating breakwater design for that purpose.

How a pontoon configuration is chosen and dimensioned

There is no single standard pontoon for every site, and Vikingegaarden deliberately publishes no one size fits all specification sheet. The pontoons are made in various sizes, shapes and configurations, and the right combination follows from the site: how exposed it is, how much the water level moves, what the structure must carry, and whether it will serve as a pier, a floating bridge, a breakwater or a platform.

Dimensioning is therefore a dialogue rather than a catalogue lookup. Vikingegaarden helps plan the layout, the element sizes and the anchoring for the specific location, and delivers pontoons that fit the water levels, tides and weather they must handle. Heavier duties, such as a floating bridge on a transport route or a breakwater on an exposed side, simply lead to a different configuration than a sheltered marina pier.

Materials: reinforced concrete around a cellular plastic core

Each element is a reinforced concrete shell cast around a cellular plastic core. The concrete provides mass and structural strength; the core provides buoyancy without relying on a sealed air chamber. Element dimensions, reinforcement, load and service-life assumptions are part of the project design.

Environmental impact cannot be inferred from the word concrete alone. It depends on material quantities, production, transport, anchoring, service life, maintenance and end-of-life treatment. Request the available declarations and project-specific material information when environmental criteria form part of procurement.

Installation and maintenance

Elements are lifted into the water, joined into the specified layout and anchored for the site. Fender rails, cleats, gangways and service equipment are coordinated with the floating structure.

The maintenance plan covers the pontoons, connections and mooring, with inspection, cleaning and repair as required. Service-life assumptions are confirmed for the chosen structure and operating environment.

The foundation of a connected marina

A pontoon is rarely the whole project. On the same elements, Vikingegaarden installs its own marina equipment: Marinella service pedestals for power and water, lighting and access control, with connected service equipment managed on the Emiko platform. Having one supplier for the floating structure and the services on top of it keeps the interfaces clean, from the anchoring below the waterline to the app the boat owner uses at the mooring.

Good to know

Frequently asked questions about concrete pontoons

What are concrete pontoons?

Concrete pontoons are floating structures made of reinforced concrete with a cellular plastic core. They serve various purposes in maritime applications, such as docks, marinas, floating bridges and breakwaters, and are designed for challenging environments.

What service life should be used when planning the project?

The project specification sets the service-life assumptions for the selected structure, exposure and maintenance plan. Components and service equipment can have different inspection and replacement requirements.

What maintenance should be planned?

Plan inspection of the structure, connections and mooring, together with cleaning and any repairs required. The maintenance schedule is set for the selected system and operating conditions.

Can concrete pontoons be customised for different projects?

Yes. Concrete pontoons can be customised in size, shape and configuration to meet the specific requirements of different waterfront projects, providing versatility in design for floating platforms, docks and marinas.

How is the environmental impact of a concrete pontoon evaluated?

Use project-specific evidence: material quantities and declarations, transport, anchoring, expected service life, maintenance and end-of-life options. Vikingegaarden does not treat the product as environmentally harmless without a documented assessment for the selected configuration.

What should a cost comparison include?

Compare the pontoon structure, mooring, installation, service equipment and maintenance over the planned service life. The site layout and operating requirements determine the complete project scope.

How do concrete pontoons float?

The reinforced concrete shell surrounds a cellular plastic core, so buoyancy does not depend on a sealed air chamber. Loading, stability and mooring are checked for the intended use and site conditions.

Can concrete pontoons provide wave protection?

A structure intended to attenuate waves must be assessed for that purpose and location. Compare the dedicated floating breakwater range when wave protection is a project requirement.

Can power pedestals and lighting be mounted on concrete pontoons?

Yes. Vikingegaarden delivers the pontoons as part of complete floating structures and installs its own marina equipment on them, such as Marinella service pedestals for power and water, lighting and access control, with connected service equipment managed on the Emiko platform.
