Kentledge is an old 17th Century term, perhaps from the old French ‘quintelage’ ballast, and ‘quintal’ a hundredweight unit of mass. Nowadays a term for nautical ballast in a ship’s hold or more commonly one of our concrete blocks used in any number of industries. You have a choice from our range of blocks to suit your Kentledge needs.

Site hoarding and fencing 

Securing one side of the fence or hoarding with hoarding blocks provides immense stability and rigidity, even where structures face severe wind loads. The effectiveness of the blocks means that support can be applied to one side only, leaving the face completely clear, unobstructed and visually pleasing.


Kentledge blocks provide 100% secure anchorage for scaffolding, including sheeted structures. The blocks add mass to the structure as well as rigidity because the anchor blocks can be mechanically integrated into the framework.

Rigging and Stageworks

Kentledge blocks make ideal counterweights on cantilevered structures, the heavy weights providing robust support on minimal footprints.

Useful for rigging staging, lighting gantries or other tubular structures, the kelly blocks can be mechanically coupled to the structures for extra rigidity and safety. Where structures have sheet cladding, such as stage or start/finish gantries, the blocks can be integrated into the core structure without visually affecting the exterior.

Marquees and events 

Providing anchorage for marquees, anchor blocks can be strapped to the main support guys, thus eliminating pegging, which may be particularly useful for hard surface marquee erections.

Cranes and towers

In addition to anchorage and stabilisation for temporary structures, our Kentledge weight blocks are ideal for the use of providing stabilisation for large cranes.

Test weights 

Our high-quality and reliable concrete kelly blocks have a wide range of additional uses. This can include as concrete test weights and ballast weights. They are designed to be able to be securely stacked so that adding weight is simple.

I have been using Maltaward for about 12 years, mostly using their traveller eviction services. They have always been very helpful and easy to deal with. No fuss, just get the job done! More recently in my new company, I have brought them in to use utilised their vacant security services. They have worked with me to provide the correct service for our specific requirements. They have a common sense approach to everything. I really cannot recommend the team enough. They have been without a doubt the best security company I have been involved with.
