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.
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.

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
