Rock protection systems for land, water and marine infrastructure.

Bora Energi supplies and supports the installation of prefilled rock protection systems across the UK and Republic of Ireland.

Used for erosion control, scour protection, flood defence and shoreline stabilisation, these systems provide a practical alternative to concrete, gabions and loose riprap across marine, coastal, river and civil infrastructure applications.

Riverbank Protection Coastal & Marine Flood Defence Offshore Ports & Harbours

Rock protection that works with the environment.

Prefilled rock protection systems are high-performance netted units filled with graded natural stone. They are placed at the point of erosion or scour risk — including riverbanks, coastlines, harbour walls, outfalls, culverts, offshore structures and infrastructure exposed to flowing water.

The systems conform to irregular ground, allow water to pass through naturally, and can support vegetation or habitat recovery where suitable. They can be used for temporary, permanent or emergency works, above or below the waterline, depending on project requirements.

Every project is reviewed individually, with product selection, rock grading, net specification, quantity, delivery and installation method assessed against the site conditions.

Reduced preparation

Systems can often be placed directly onto existing ground or underwater surfaces, reducing the need for excavation, formwork or poured concrete.

Flexible installation

Suitable for crane, excavator or marine placement, depending on access, unit size and project conditions.

Temporary or permanent use

Can be used for planned permanent protection, temporary works, construction support or emergency response.

UK & Republic of Ireland coverage

Bora Energi supports supply, delivery and installation planning across the UK and Republic of Ireland.

All products are specified and quoted individually. Rock type, fill size, net specification, quantity, delivery and installation all feed into the final price — send us your project details and we will respond with a clear quotation.

Rock Protection Units

Individual prefilled stone units designed for erosion control, scour protection and localised stabilisation. Typical uses include riverbanks, culverts, outfalls, harbour structures, offshore assets and temporary works.

  • Available in a range of sizes and fill weights
  • Project-specific rock type and grading
  • HDPE or PET netting options
  • Suitable for above or below-waterline use
  • Can be placed by excavator, crane or marine spread
  • Temporary or permanent applications

Rock Mattresses

Large-format prefilled rock systems formed to provide continuous protection over a wider area. Suited to high-flow environments, sloped surfaces, reservoir spillways, major riverbanks, shorelines and offshore structures.

  • High resistance to hydraulic loading
  • Conforms to irregular or sloped surfaces
  • Suitable for large-area protection
  • Useful for high-velocity water environments
  • Can support shoreline, reservoir and offshore applications

Rock Rolls

Flexible cylindrical prefilled stone units, particularly suited to riverbanks, canals, watercourses and below-waterline edge protection. Can be deployed individually or connected to form wider protection systems.

  • Flexible and easy to place
  • Suitable for uneven bed profiles
  • Effective for river, canal and tidal applications
  • Can be used above or below the waterline
  • Available in multiple diameters and lengths

Applications

From riverbanks to offshore structures.

Temporary works

Emergency response

Pipeline and cable protection

Culverts and outfalls

A practical alternative to concrete-heavy protection methods.

Traditional erosion control methods such as concrete revetments, gabions and loose riprap can require significant preparation, access, plant and installation time.

Prefilled rock protection systems provide an alternative approach. They can be delivered to site ready for placement, installed above or below the waterline, and selected to suit the required design life, hydraulic conditions and project constraints.

They are particularly useful where clients need:

Procurement-ready

For clients operating under procurement rules requiring multiple quotations, Bora Energi is a qualified and responsive alternative supplier across the UK and Republic of Ireland.

Ready for placement

Products are delivered to site prefilled and ready for placement — no on-site mixing, formwork or curing time required.

Above and below waterline

Suitable for installation above and below the waterline, including in tidal, riverine and offshore environments.

Competitively priced

We are positioned to offer competitive pricing across the UK and Republic of Ireland — including against established suppliers.

UK & Republic of Ireland

Bora Energi supports projects across the UK and Republic of Ireland, with particular focus on developing supply and installation capability in the Irish market.
