Aggregate Industries Dense Concrete Block (L)440mm (W)100mm

Easy to use and work with and easy to handle to make a wall with

I built a raised planter in the garden out of these blocks and painted them... they are very heavy but all robust and in good order; I didn’t have any problems with their quality unlike other reviews... planter is very solid... bought more to build a pond structure and all seem great...

I bought 350 of these 8 weeks ago. I've just started using them and they are terrible. I would say I have about 25 blocks cracked in half before even using them. They are 95mm not 100mm. Edges are all rounded off, and they're really crumbly. Not like the normal grey dense blocks I've used before. These are a pink colour and just rubbish to be honest. I wish I had rejected them and told B&Q to come and pick the lot up again.

I usually don't leave reviews but on this occasion seeing all the bad reviews about this blocks I want to say that these in my case where really good. Didn't crumble or break easily. I have used them to build my garage on the inside and bricks on the outside. Really satisfied with them.

These are very poor quality blocks. I ordered 400 and a lot of them simply broke in half when picking them up. The edges are all knocked off and rounded. Worst of all they are not the size advertised. They are 95mm wide not 100.
