Bridge Abutments - Erosion Control with Earthlok
Bridge abutments are critical structural components that support the ends of a bridge span and anchor it to the ground.
Flexible Erosion & Scour Protection for All Types of Bridge Abutments
- EARTHLOK™ offers a proven erosion control solution for abutments of bridges using innovative, Australian-made concrete mat systems. Our flexible concrete mats are designed to reduce erosion around abutments and slopes, offering permanent hard armour protection for long-term structural stability.
- Whether you’re working on a new construction project or reinforcing an existing structure, Earthlok concrete mats are versatile enough to adapt to different abutment bridge designs and site conditions.
- These structures bear the vertical and horizontal loads of the bridge, and they are often exposed to harsh environmental conditions such as heavy water flow, flooding, and erosion. To maintain long-term performance and safety, protecting bridge abutments from erosion and soil displacement is essential.
Why EarthLok™ for Bridge Abutments?
- Unmatched Erosion Protection: EARTHLOK™ mats are designed to resist water flow, sediment movement, and weather impacts, shielding the base of the abutments and the surrounding substrate.
- Long-Lasting Durability: Our system offers a service life of 50+ years (non-vegetative) and 100+ years (vegetative), making it ideal for civil infrastructure.
- Easy Installation: Delivered in rolls, EARTHLOK™ mats can be installed without concrete pouring or curing time, saving labour, time, and machinery costs.
- Eco-Friendly Solution: EARTHLOK™ supports vegetation growth with biodegradable underlays and uses recycled materials for a lower carbon footprint.
- Adaptable to Steep Slopes: With pyramid-shaped concrete blocks, interlocked with flexible geogrid and having a geotextile underlay, EARTHLOK™ conforms to curved or sloped surfaces without compromising structural integrity.
Designed for Harsh Conditions
Bridge abutments are often subjected to repeated cycles of wet and dry conditions, high-velocity water flow, and fluctuating soil stability. These pressures can cause erosion, undercutting, and long-term damage if left untreated.
EARTHLOK™ provides an effective barrier that:
- Anchors into the subgrade under hydraulic pressure
- Slows water flow and reduces energy
- Prevents soil displacement and surface runoff
- Minimises maintenance requirements over time
With EARTHLOK™, civil engineers and contractors gain peace of mind knowing their abutments are protected against environmental wear and erosion.

Bridge Abutments - FAQs
What are bridge abutments used for?
Bridge abutments support the bridge deck at each end and retain the approach embankment. They play a crucial role in structural stability and load transfer.
Why do bridge abutments need erosion control?
Erosion can undermine the foundation of abutments, leading to structural instability. EARTHLOK™ helps prevent this by protecting the soil and dispersing hydraulic forces.
Can EARTHLOK™ be used on steep slopes near abutments?
Yes. EARTHLOK™ is flexible and conforms to various surfaces, including steep and curved slopes commonly found around abutments of bridges.
How does EARTHLOK™ compare to rip rap for abutments?
EARTHLOK™ concrete mats offer a durable, low-maintenance alternative to traditional rip rap by providing permanent hard-armour protection that is designed to last without requiring constant reinstatement due to wash-out issues common to rip rap. Delivered in easy-to-install rolls and backed by over 50 years of service life (100+ years when vegetated), the flexible, pyramid-shaped blocks interlock over a UV-stabilised geogrid to conform to slopes, promote vegetation growth and dramatically reduce ongoing maintenance.
