Durable concrete structures designed for coastal environments, island access and waterfront conditions.

From jetties to seawalls, we deliver marine-grade construction built to perform under pressure.

Concrete Solutions

Marine & Waterfront

Marine and waterfront construction presents a unique set of challenges.

Exposure to tidal movement, water pressure, erosion and salt conditions demands the right preparation, materials and structural approach. These environments leave little room for shortcuts.

At Gnarly, we approach marine works with the same discipline we bring to commercial and infrastructure projects — careful planning, precise preparation and execution aligned with engineered specifications.

Our Marine & Waterfront Capabilities.

We provide marine and waterfront concreting services across North, Central and South Brisbane’s bayside regions.

Structural concrete systems designed to manage water movement and ground stability.

Erosion Control Works

Driveways, patios and structural slabs built for coastal environments.

Waterfront Slabs & Foundations

Engineered solutions to stabilise shorelines and protect waterfront properties.

Sea walls & retaining walls

Reinforced structures designed for durability in tidal environments.

Jetty & Pier Construction

Durable concrete bases and structures supporting waterfront access and infrastructure.

Marine Platforms & Floating Pontoons

Yes — we regularly coordinate with engineers, builders and other trades to ensure the project aligns with plans and site requirements. Clear communication and structured execution are key on these types of projects.

Can you work alongside other contractors or engineers on marine projects?

Yes — we construct seawalls, retaining structures and other concrete solutions designed to stabilise waterfront areas. These works are approached with a focus on long-term strength and resistance to environmental pressure.

Do you handle erosion control and shoreline stabilisation?

Yes — we regularly coordinate projects in locations such as Stradbroke, Russell and Moreton Island. Access, logistics and equipment planning are managed as part of the project to ensure smooth delivery.

Can you complete projects on islands or difficult-access sites?

Marine projects are exposed to moisture, movement and erosion, so we focus heavily on reinforcement, material selection and structural preparation. When these elements are handled properly, the concrete is built to perform long-term in harsh conditions.

How do you ensure the concrete holds up in coastal conditions?
