Bridge Abutments and Structural Supports
Legato® Interlocking Concrete Block Systems by Elite Precast.
Elite Precast manufacture Legato® interlocking concrete blocks, providing a robust, modular and cost-effective alternative to traditional in-situ reinforced concrete solutions for bridge abutments and structural support walls.
Manufactured from high-strength 50N/mm² concrete, Legato® blocks deliver exceptional load-bearing performance, long-term durability and rapid installation for highway, rail, civil engineering and infrastructure projects.
What Are Legato® Interlocking Concrete Blocks?
What Are Bridge Abutments and Structural Supports?
Bridge abutments and structural supports are critical load-bearing elements designed to:
Support bridge decks and superstructures
Retain embankments and approach fills
Transfer vertical and horizontal loads safely into the ground
Resist lateral earth pressures, surcharge and dynamic loading
Legato® interlocking concrete blocks form gravity-based structural systems that rely on mass, interlock and precise geometry, rather than mortar or steel reinforcement.
Why Choose Elite Precast
With decades of precast expertise, in-house engineering support and a proven delivery record on projects of every scale, Elite Precast is the partner specifiers trust. We pair robust, repeatable manufacturing with the flexibility to engineer bespoke solutions when a standard product will not do.

Engineered for Your Environment
Design, Stability and Compliance
Bridge abutments and structural supports using Legato® blocks must be designed to account for:
Vertical loads from superstructures
Lateral earth pressures
Surcharge loads from traffic and backfill
Ground bearing capacity
Drainage and water management
Wind and dynamic loading
Legato® block systems are designed in accordance with BS EN 1992-1-2004 (Eurocode 2) for concrete structural design.
Elite Precast provides access to its Stability and Loadings Directory to support engineers and contractors during the design phase.
⚠️ Important: All bridge abutments and structural support walls must be checked and approved by a qualified structural engineer prior to construction.
Installation and Safety Considerations
Ensure a suitable, level and well-compacted base
Allow retained material to naturally form against the structure
Inspect blocks and lifting pins prior to installation
Assess wind loading for exposed or single-skin walls
Avoid direct impact from mobile plant
