850kg Concrete Ballast Blocks
Versatile counterweights for scaffolding, site security and temporary structures
Why choose 850kg concrete ballast blocks?
These compact counterweights are a practical choice for contractors, event organisers, and site managers.
- Buy or hire – available for short- or long-term hire, or outright purchase.
- Greater holding capacity – weighing 850kg, they provide extra stability for scaffolding, hoarding, and site set-up.
- Linkable blocks – cast-in 68mm diameter holes allow you to connect multiple blocks with scaffold poles, creating heavier combined ballast.
- Practical handling – fork recess in the base allows it to be lifted with a 2.5T Deha clutch, making transport easy.
- Better than plastic or water-filled weights – no leaks, no cracks, no refilling; just reliable ballast.
- Customisable options – we can add Halfen channels, eyebolts, or extra lifting points if required.
With 850kg concrete ballast blocks, you’ll get:
Response from the team within 4 working hours
Flexible hire or buy options, short or long term
UK-wide delivery with optional offload & placement service
Heavy-duty ballast with linking options
When site access is tight or you need flexible anchoring, 850kg concrete ballast blocks give you stability without the need for fixings.
Each block features a fork recess in the base for easy handling and a cast-in hole through both length and width, allowing you to connect multiple blocks together with scaffold poles.
This makes them ideal for scaffolding ballast, hoarding, fencing, or any application where a non-invasive counterweight is needed.
Product Features & Specifications of Ballast Blocks
Our 850kg concrete ballast blocks are built for durability, flexibility, and safe handling. Here’s what makes them distinct.
Concrete strength: C40 mix
Manufactured using a high-strength concrete mix, ensuring long-lasting performance even with repeated use.
Connection: Flat edges (non-interlocking)
Flat-sided blocks provide flexibility in positioning, without interlocking constraints.
Edge detail: Chamfered edges
Chamfered edges minimise visible chipping and create a cleaner appearance, especially on visible sites.
Concrete finish: Mould finish on all visible faces
A smooth mould finish offers a professional look; non-visible faces are hand-trowelled.
Design life: 50 years+
Engineered for long-term durability, with a service life exceeding typical site requirements.
Reinforcement cover: N/A (unreinforced)
No steel inside the blocks means no risk of corrosion, ensuring consistent weight and stability.

Applications for 850kg ballast blocks
The 850kg block is especially popular for scaffolding ballast, where connecting multiple blocks with scaffold poles forms a stable, heavy-duty counterweight.
They’re also commonly used for site setup and security, anchoring hoarding and fencing, and in event management, where a heavier block is required for cabins, stages, or larger structures. With the ability to combine units, they offer a flexible solution wherever non-invasive anchoring is needed.
