Kentledge Blocks for Onshore Wind Farm Construction
Reliable, Sustainable Foundation Solutions for Modern Wind Energy
Ballast blocks are a proven, efficient, and sustainable foundation solution for onshore wind farm construction. Designed to provide stability without extensive ground penetration, Kentledge ballast blocks are increasingly used where soil conditions, environmental constraints, or project timelines make traditional foundations challenging. Our engineered Kentledge Blocks deliver the structural integrity required to support wind turbines, substations, temporary crane pads, and ancillary infrastructure, all while reducing environmental impact and accelerating installation.
What Are Kentledge Blocks?
What Are Kentledge Ballast Blocks?
Kentledge blocks are high-density precast concrete blocks used to provide mass and stability for wind turbine foundations and related infrastructure. Rather than relying solely on deep excavation or piling, ballast blocks distribute loads across a wider surface area, making them ideal for sites with poor ground conditions, high water tables, or strict environmental regulations.
They can be deployed as part of permanent or semi-permanent foundation systems and are well suited to both greenfield and repowering projects.
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
Key Applications in Onshore Wind Farms
Wind Turbine Foundations — Kentledge blocks can be used as part of gravity-based foundation systems, particularly where piling is impractical. Their modular design allows for rapid installation and precise load distribution, ensuring long-term turbine stability.
Crane Pads and Hardstands — Heavy-lift cranes are essential during turbine installation and maintenance. Kentledge blocks provide robust, level crane pads capable of supporting extreme point loads without extensive groundworks.
Substations and Electrical Infrastructure — Kentledge ballast blocks offer a stable base for substations, transformers, and switchgear, helping protect critical equipment from settlement and ground movement.
Temporary Works and Access Roads — For temporary construction phases, ballast blocks can be installed quickly and removed or reused once the project is complete, reducing waste and reinstatement costs.
Benefits
Reduced Ground Disturbance — Minimal excavation preserves soil integrity and local ecosystems.
Faster Installation — Precast units significantly shorten construction schedules.
Adaptable to Challenging Ground Conditions — Ideal for peat, clay, or high-water table sites.
Lower Environmental Impact — Reusable and recyclable concrete solutions.
Predictable Performance — Factory-controlled production ensures consistent quality.
Cost Efficiency — Reduced labour, plant, and programme risk.

Frequently Asked Questions
Are Kentledge blocks suitable for all soil types?
Kentledge ballast blocks are particularly effective in poor or variable ground conditions such as peat, clay, and made ground. A geotechnical assessment is always recommended to confirm suitability for specific sites.
Can kentledge blocks be used as permanent foundations?
Yes. When correctly engineered, ballast block systems can form part of permanent gravity-based foundations for onshore wind turbines and associated infrastructure.
How quickly can Kentledge Blocks be installed?
Installation is typically much faster than traditional poured-in-place foundations. Precast blocks can often be installed within days, depending on project scale and site access.
Are kentledge blocks reusable?
Yes, one of their key advantages is reusability. Blocks can be removed, relocated, or repurposed for future wind projects, reducing waste and lifecycle costs.
Do kentledge blocks meet wind industry standards?
Our ballast blocks are designed to meet relevant structural, load-bearing, and durability standards applicable to onshore wind farm construction. A project engineer is responsible for project sign off.
Can kentledge blocks be customised?
Absolutely. We offer bespoke designs including size, weight, reinforcement, and lifting configurations to meet specific turbine models and site conditions.
