Retaining and Pendine Walls
A Flexible, UK-Manufactured Solution from Elite Precast Concrete
Elite Precast Concrete is the sole UK manufacturer of Duo™ interlocking concrete blocks, providing a robust, adaptable and cost-effective solution for constructing retaining walls and pendine walls across industrial, commercial, agricultural and waste management sites.
Duo™ blocks offer exceptional strength and stability while allowing fast installation, easy reconfiguration and long-term reuse, making them an ideal alternative to traditional in-situ concrete walls.
What Are Duo™ Interlocking Concrete Blocks?
Why Choose Duo™ Blocks for Retaining & Pendine Walls?
Retaining and pendine walls are required to safely contain loose or bulk materials while withstanding lateral loads and site traffic. Duo™ interlocking concrete blocks are specifically designed to meet these demands without the need for permanent foundations or complex construction methods.
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.
Key Applications
Duo™ interlocking blocks are widely used for retaining and pendine walls in the following settings:
Aggregate and mineral storage yards
Salt and grit storage facilities
Waste and recycling plants
Composting and biomass operations
Agricultural grain and feed storage
Temporary retaining walls for site development
Industrial stockyard separation and containment
The system allows materials to naturally form against the wall, reducing point loading and improving overall stability.
Benefits
Key Advantages
High mass and interlocking design for enhanced wall stability
Dry-laid construction – no mortar, fixings or curing time required
Rapid installation using standard lifting equipment
Modular and reconfigurable to suit changing site layouts
Fire-resistant and durable, ideal for demanding environments
Temporary Structures with Commercial Benefits
Retaining and pendine walls constructed using Duo™ blocks are typically classed as temporary or semi-permanent structures. As the blocks are dry-laid and fully reusable:
Planning permission is often not required (subject to local authority approval)
Structures can be dismantled and relocated as site needs change
Business rates may be reduced compared to permanent builds
Installation costs are significantly lower than in-situ concrete walls
Engineered for Your Environment
Design Flexibility and Wall Configuration
Duo™ interlocking concrete blocks can be configured to create straight, stepped or cornered retaining walls, with wall height determined by:
Block size and layout
Retained material type and density
Ground bearing capacity
Wind loading for exposed or freestanding walls
Elite Precast Concrete provides access to stability and loading guidance to support safe and compliant wall design.
Durability and Fire Resistance
Manufactured from high-quality precast concrete, Duo™ blocks provide:
Excellent resistance to impact, weathering and freeze–thaw conditions
A choice of moulded or trowelled faces, depending on visual requirements
The concrete finish is classed as basic in accordance with the National Structural Concrete Specification.
Compliance and Technical Support
Duo™ interlocking concrete blocks are manufactured in compliance with:
BS EN 1992-1-1:2004 – Design of Concrete Structures
Elite Precast Concrete offers:
Design and installation guidance
Stability and loading calculations
Structural and foundation design reviews upon request
Prior to construction, customers are advised to review ground conditions and material loadings to ensure suitability.
Safety and Installation Considerations
Walls must be constructed on a firm, level surface with adequate bearing capacity
Wind loading should be considered for freestanding walls over certain heights
Blocks should be inspected for damage before lifting or reuse
Direct impact from mobile plant should be avoided
It is the customer's responsibility to ensure appropriate structural checks are carried out before installation.
