Frequently asked questions

What does the ballast block weigh when filled?

The body is about 1.80kg empty and roughly 20.8kg once filled, depending on whether you use concrete, sand or water. That gives enough weight to steady a HERAS panel on hard ground.

What can I fill it with?

You can fill it with concrete, sand or water through the cap on top. Denser fill like concrete or sand gives the most holding weight; water is quicker where you need to move the fence often.

Does it fit standard HERAS fencing feet?

Yes. It sits over the ends of most standard fencing feet, adding weight to the base so the panel stays put on hard surfaces where stakes cannot be driven in.

How do I fill and empty it?

Lift the removable cap on top to fill, then refit it to seal the body. When the fence comes down, take the cap off and empty the contents through the same opening.

What are the dimensions?

The block measures 68.3cm wide, 29.5cm high and 31.5cm deep, with a 20 litre fill capacity.

Can the blocks be stacked for storage?

Yes. The stepped profile lets the blocks stack together, so they store and transport in a compact space when empty.

Is it suitable for outdoor and event use?

Yes. The hi-vis safety yellow keeps the fence line visible around events and on site, and the sealed cap keeps the fill clean outdoors.
