HEX-LOC^® is our core brand, named for its hexagonal, interlocking modular block design used across a range of civil applications.

EcoReef^® refers specifically to our coastal solution range, originally designed by Fred Waiker. We continue to use Fred’s original design, which has built a strong reputation in the market and has been successfully deployed in numerous coastal builds.

The HEX-LOC^® system offers outstanding design flexibility through its unique hexagonal shape. This allows potential configurations to be adapted over a wide variety of site conditions. We are yet to encounter a situation where HEX-LOC^® would not benefit your project.

The full-size module is the primary building block, but it can be seamlessly combined with other module variants, all of which share the same interlocking capabilities and design benefits. This modular approach enables structures to follow straight lines or contour naturally to existing land profiles, reducing installation costs and providing effective solutions for complex or uneven terrain.

HEX-LOC^® gains its strength from the unique castellations that allow each hexagonal module to interlock securely with the blocks above and below. This ensures every block is fully encapsulated, forming a robust, modular structure.

The strength comes from the collective formation rather than relying on any single module, delivering enhanced durability and stability across the entire installation.

HEX-LOC^® is designed to minimize the use of man-made materials by utilising natural site fills for erosion protection. This approach reduces the need for imported rock or engineered fill, and lowers transportation costs, helping to limit the impact of heavy transport on our roading networks.

By working with the existing landscape and reducing resource demand, HEX-LOC^® supports more sustainable construction practices and environmentally conscious site development compared with alternative products on the market.

Yes. The castellations and contact faces of HEX-LOC^® have been specifically designed to accommodate up to 10 degrees of flexibility, allowing the modules to conform to contoured or uneven ground without compromising structural integrity.

This makes HEX-LOC^® suitable for installation on soft or saturated soils, while still maintaining a strong, interlocked formation. While some soil conditions can prove challenging, if your project has high demand to minimize tolerances, some foundation preparation can be of benefit prior to placing the first modules.

EcoReef^® features a unique hexagonal design that, unlike flat seawall structures, helps deflect waves and dissipate wave energy upon impact. Site specific geometry can be configured to absorb the forces of incoming waves and minimises erosion.

Early evidence suggests that the modules naturally encourage sand and gravel to accumulate against the structure, providing nourishment. At the same time, the modules are fully free draining, allowing water to pass through quickly and preventing pooling or pressure build up.

HEX-LOC^® is designed as a robust, long-term solution with little requirement for ongoing maintenance. Like any engineering solution, HEX-LOC^® can integrate to your asset management platform keeping your OPEX in check.

HEX-LOC^® has been designed and approved in Government projects requiring a design life of 100 years. If your project involves critical infrastructure or lifelines that attract design criteria in excess of this, we can readily adjust our moulds to suit.

HEX-LOC^® has been designed and approved in Government projects requiring seismic loads of 7.5Mw (DCLS) and 6.7Mw (SLS). Performance can be verified using pseudo-static slope stability modelling to the design pga’s or your seismic hazard zone.

The unique interlocking design of HEX-LOC^® ensures each module is securely encapsulated by the blocks above and below, sharing the hydraulic load. This significantly reduces stress on individual blocks and enhances overall stability under pressure. This creates a form of gravity retaining wall, and that allows the geometry to be adjusted to resist hydraulic loads. Wave forces, drag, rapid-draw down and debris are all considered together with earth pressures and any surcharges.

Additionally, each module features three-point seating, which ensures optimal load bearing and weight distribution, even on uneven or contoured ground. This interlocking, referred to as castelling, develops the necessary internal shear that hold the structure intact.

HEX-LOC^® can be toed-in to any depth provided excavation permits a safe working environment. While working in and around water can be challenging, and often requires sound methodology to meet resource consent requirements, it sets the project up to be successful. Unlike rock rip-rap, there is no need for particular gradings, thicknesses, or risk of incompatibility with finer soils causing washing out and slumping. Rock can crack when being dumped and loaded, while our modules are carefully manoeuvred into place. This means our designs can meet your quality control needs, and if required, each module can be individually approved during installation.

Modules can be efficiently stacked three high and offset along the deck to maximize load capacity.

• A smaller Hiab truck and trailer can carry approximately 33 full-size modules, totalling around 21 tonnes.
• A larger truck and trailer can transport up to 48 modules, equating to roughly 30 tonnes.

Each full-size HEX-LOC^® module is fitted with three SwiftLift™ anchors on the top surface, while half modules have two SwiftLift™ anchors. These lifting points allow for safe and efficient handling during transport and installation.

HEX-LOC^® has developed a tri-lifter system that enables three blocks to be moved simultaneously. This significantly accelerates module handling during both transportation and installation, improving overall efficiency on site.
