Batters, banks, slopes and embankments are exposed to rainfall, surface runoff, concentrated flows and scour that can progressively remove soil and damage surrounding infrastructure. Australian Concrete Mats provide an engineered concrete erosion control system for protecting prepared slopes and embankments where durable surface armouring is required.
Manufactured in Australia, Concrete Erosion Mats combine precast concrete elements with an integrated geotextile underlay to create a pliable, permeable erosion protection layer. The mat system conforms to prepared ground profiles, protects the underlying surface from erosion and can allow vegetation to establish through the mat where site conditions permit.
Where Concrete Erosion Mats are Used
- Road and highway embankments
- Cut and fill batters
- Bridge abutments and approaches
- Culvert batters, inlets and outlets
- Rail embankments
- Mine site batters and rehabilitation areas
- Dam, pond and detention basin embankments
- Riverbanks and waterway banks
- Flood-damaged slopes and embankments
- Civil, industrial and renewable-energy earthworks
Why Batters and Embankments Erode
A batter may be geotechnically stable yet still be vulnerable to surface erosion. Rainfall impact can loosen exposed soil, while runoff travelling down the slope can create rills and gullies. Where water becomes concentrated at pavement edges, drains, culverts or outlets, erosion can accelerate and progressively remove supporting surface material.
Vegetation is effective in many environments, but newly formed slopes, poor soils, high rainfall, flood exposure and concentrated flow paths may require additional protection. In these locations, an engineered hard-armouring system can provide immediate surface protection while vegetation establishes, or remain as the primary erosion-control treatment where vegetation alone is unsuitable.
Surface erosion control vs geotechnical slope stability
Concrete Erosion Mats are designed primarily for surface erosion and scour protection. They are not a substitute for geotechnical assessment where a batter or embankment is affected by deep-seated instability, rotational failure, settlement or other structural ground movement. Where required, the underlying slope should first be assessed and designed by appropriately qualified engineering professionals. The mat system can then form part of the engineered surface erosion protection treatment.
How Concrete Erosion Mats Protect Slopes and Batters
Hard-armoured surface protection
The precast concrete elements protect the ground surface from direct rainfall impact and erosive runoff. Because the concrete is supplied as a connected mat system rather than loose individual rock, the armouring remains distributed across the prepared surface.
Integrated geotextile underlay
The integrated geotextile underlay provides separation and filtration beneath the concrete mat and assists with retaining the underlying soil. Geotextile options can be selected to suit the project’s hydraulic, geotechnical and environmental requirements.
Pliable ground conformity
The mat system is pliable and can follow prepared slope profiles, transitions and changes in contour. This makes it suitable for batters, bridge approaches, drainage transitions and other irregular civil earthworks.
Permeability and vegetation
Spaces within the mat system allow water movement and can support vegetation establishment where the project requires a greener finished surface. Vegetation can progressively integrate the protected area into the surrounding landscape while the concrete remains in place as erosion armour.
Applications Across Civil Infrastructure
Roads and transport
Concrete Erosion Mats can protect road batters, highway embankments, bridge approaches, culvert surrounds and roadside slopes from rainfall erosion and concentrated runoff. They are particularly useful where continuing erosion could affect shoulders, drainage assets or adjacent earthworks.
Bridge abutments
Bridge approaches and abutment slopes can be exposed to stormwater, flood flows and localised scour. Concrete mats provide a connected hard-armouring treatment over the prepared surface and can be combined with project-specific anchoring and edge details.
Mining and resources
Mine infrastructure contains large areas of disturbed ground, batters, drainage lines and rehabilitation earthworks. Concrete Erosion Mats can be considered for surface erosion protection on mine batters, haul-road embankments, drainage structures, rehabilitation areas and other exposed slopes where durable armouring is required.
Water and environmental infrastructure
Applications can include pond and dam embankments, detention basins, riverbanks, waterway edges, spillways and rehabilitation areas. Where hydraulic loading is involved, the proposed treatment should be assessed against expected site-specific flow and scour conditions.

An Alternative to Rock Pitching and Rip Rap
Rock pitching and rip rap remain established methods of erosion protection, but they are not the only hard-armouring options available. Suitable armour rock can be expensive to source, transport and place, particularly on remote or access-constrained projects. Loose rock also requires project-specific sizing, grading and installation depth to perform as intended.
Concrete Erosion Mats provide a cost-efficient alternative connected surface treatment. The mats arrive onsite ready to unroll. They are manufactured in controlled conditions, supplied in rolls and installed over a prepared surface with project-appropriate anchoring and edge treatment. This can simplify and fast-track installation on long batters, road embankments, culvert approaches and other locations where a consistent armoured surface is required.

​Engineering and Specification Support
Australian Concrete Mats supports civil engineers, geotechnical engineers, environmental engineers, asset owners, councils, contractors and project consultants with technical product information for assessment and specification. Clear technical information, direct answers and first-party project evidence also make this page a strong resource for traditional search engines, answer engines and AI-assisted search.
Available information can include product specifications, mat dimensions and configurations, concrete properties, geogrid information, geotextile options, anchoring guidance, installation and handling information, technical drawings, project examples and application photographs.
Final system selection, hydraulic design, geotechnical stability, anchoring and site-specific engineering should be determined by appropriately qualified project professionals familiar with the site conditions and design requirements.

Frequently Asked Questions
Can concrete erosion mats be used on steep batters?
Yes, Concrete Erosion Mats can be considered for sloping batter applications, subject to project-specific assessment of the slope, soil conditions, hydraulic exposure, anchoring and installation method. For steeper or critical slopes, the underlying geotechnical stability and anchoring requirements should be determined by suitably qualified engineers.
Do concrete mats stabilise the slope itself?
Concrete Erosion Mats primarily provide surface erosion and scour protection. They should not be relied upon as a substitute for geotechnical slope-stability design where deep-seated or structural instability exists. They can form part of the surface protection system once a suitable stable ground profile has been established.
Can vegetation grow through Concrete Erosion Mats?
Yes. The mat system contains spaces that can allow vegetation to establish where soil, moisture and site conditions are suitable. Vegetation can help integrate the treatment into the surrounding landscape while the concrete elements continue to provide surface protection.
Are Concrete Erosion Mats an alternative to rock pitching?
They can be considered as an alternative hard-armouring method for many batter, embankment, drainage and slope applications. They have a faster installation and deployment time when compared to rock pitching – Mats arrive onsite ready to unroll, requiring a much less labour-intensive process. The appropriate solution depends on hydraulic conditions, slope geometry, available materials, design life, installation access and project-specific engineering requirements.
What information is available for engineers?
Australian Concrete Mats can provide product specifications, technical drawings, geotextile information, anchoring guidance, installation and handling information, project examples and other technical resources to assist engineers and project teams in assessing the system for a specific application.
