Concrete blocks come in a range of densities, which has the biggest impact on what a concrete block can weigh. It goes without saying that they should be handled with care, and decent safety footwear is essential in case you drop one on your toes!
If you are using a large number of heavy dense concrete blocks, it may be a good idea to deploy lifting equipment to transport and set out the blocks.
Palletised blocks can be delivered kerbside, as close to the working area as possible.
What are the Heaviest Concrete Blocks?
The heaviest blocks are, without doubt the 140mm solid dense blocks which can weigh in at up to 25kg, the same as a bag of cement.
A 100mm solid dense block will come in at about 18.5kg, so you will have to be aware of best practise when it comes to manual handling.

Best Practice:
- Always wear gloves when handling blocks to ensure best grip.
- Load out blocks to a position as close as possible to the working area.
- When loading out use a wheelbarrow or other equipment to transport them to the working area.
- Only lift as much as feels comfortable. One concrete block at a time is fine.
What are the Lightest Concrete Blocks?
Coursing blocks are the lightest, but that is because they are smaller than regular blocks and used to level up courses and infill gaps. Coursing blocks are a similar size to bricks and can be used to save cutting blocks around window and door openings or making up a wall to the right height.
Lightweight aerated concrete blocks are light enough for a regular person to lift with one hand but are still strong enough to be used in all sorts of applications.
Hollow blocks are the easiest to lift with one hand gripping the outside face and inner part of the block. These concrete blocks are perfect for non-load-bearing internal partition walls.
How Much Does a Pallet of Blocks Weigh?
A pallet of blocks can weigh anything up from 1 to 1.7 tonnes. It is essential to know this when you are deciding how to get your concrete blocks to site.
Most of the time it’s best to pay for delivery direct from the supplier, along with all the other building materials you require.
Always check the rating on your trailer, or van before attempting to collect palletised blocks to make sure your vehicle is capable of taking the weight.
Best Practise:
- Never overload your scaffold with more blocks than it can handle.
- Your scaffolder will be able to advise, but a medium-duty scaffold should be able to support 240 kg per square metre.
- A medium duty scaffold can handle a stack of a dozen blocks per square metre.
- In practise, this will be able to support your bricklayer, their mortar and other materials for a M2 of wall across a 2M working area.
- Always leave room to work!
