Precast Retaining L-Wall Blocks for Highways, Basements & Industrial Developments

Drsti Precast is a leading manufacturer of high-performance precast concrete products, delivering quality, precision, and reliability across infrastructure, industrial, and urban development projects. With advanced production facilities, automated mould systems, and strict quality control, Drsti Precast ensures every product meets superior strength, durability, and dimensional accuracy. Our solutions are designed for faster installation, consistent performance, and long-term value, making us a trusted partner for architects, developers, and contractors nationwide. 

An L-Wall block is a precast RCC retaining structure shaped like the letter “L”, consisting of a vertical stem and a horizontal base slab. The stem retains the backfill soil while the base resists overturning and sliding through its self-weight and soil bearing pressure. Precast L-Walls are modular, factory-made elements that can be quickly installed at site using cranes, providing a faster, cleaner, and more economical alternative to conventional cast-in-situ retaining walls. 

Drsti’s L- Shape Wall Blocks are suitable for highway and railway embankments, plot and villa developments, basement retaining walls, industrial and logistics parks, and landscape level differences. They are ideal for builders, developers, contractors, architects, and infrastructure companies seeking quick-to-install, durable, and maintenance-free retaining solutions. Each unit can be customized in height, base width, and finish to suit site-specific load and aesthetic requirements. 

Choose Drsti Precast for engineered precision, rapid installation, and unmatched quality in retaining wall systems. Our team provides complete support from design to delivery, ensuring structural safety and project efficiency.

Technical Specification:

This L-shaped retaining wall is designed to accommodate pedestrian or bicycle barriers or fences installed at its top.

• The horizontal load on the guardrail is considered as 0.39 kN/m.

• Two variations are available, each with different superimposed load conditions.

• L - Wall Block - A Series

Design Conditions

• Concrete unit weight: γ c = 24.5 kN/m³

• Friction coefficient: μ = 0.6

• Earth pressure calculation: Trial wedge method

• Embankment slope: Horizontal

• Fence load: P = 0.39 kN/m, applied at the top of the parapet

Load Combinations

• Normal load (long-term): Earth pressure + dead weight + surcharge load

• Fence load (short-term): Earth pressure + dead weight + superimposed load + fence load
