Counterweights and Kentledge Solutions

Legato® Interlocking Concrete Blocks by Elite Precast

Elite Precast supplies high-performance counterweights and kentledge systems using Legato® interlocking concrete blocks, providing a safe, flexible and cost-effective solution for stabilising structures, plant and temporary works.

Manufactured from 50N/mm² high-strength concrete, Legato® blocks deliver exceptional mass, durability and reliability without the need for steel reinforcement, permanent fixings or bespoke cast units.

What Are Legato® Interlocking Concrete Blocks?

What Are Counterweights and Kentledge?

Counterweights and kentledge are used to:

  • Provide stabilising mass to resist uplift, overturning or sliding

  • Anchor temporary or permanent structures

  • Support cranes, gantries and lifting equipment

  • Stabilise hoardings, barriers and temporary works

  • Provide ballast for structural testing and load simulations

Legato® interlocking concrete blocks form gravity-based kentledge systems, relying on their mass and interlocking geometry rather than mechanical connections.

Engineered for Your Environment

Design & Engineering Considerations

Counterweights and kentledge systems must be designed to account for:

  • Required stabilising loads

  • Load combinations and safety factors

  • Ground bearing capacity

  • Wind loading

  • Block configuration and stacking arrangement

Elite Precast provides access to its Stability & Loadings Directory, offering guidance on block weights, stacking layouts and ground requirements.

⚠️ Important: All counterweight and kentledge arrangements must be checked and approved by a qualified structural engineer before installation.

Installation and Safety Guidance

  • Ensure blocks are placed on a suitable, level and stable base

  • Inspect blocks and lifting pins prior to use

  • Avoid impact damage during handling

  • Do not exceed recommended stacking heights

  • Consider strapping or restraint where dynamic loads are present

Compliance and Performance

  • Designed in accordance with BS EN 1992-1-2004 (Eurocode 2)

  • Class A1 Fire Resistant

  • Suitable for public sector, infrastructure and industrial projects
