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

Got them with 10% off, unfortunately one fell in half when I unloaded them, not a bad block though.

Used to build raised garden and some to brick up chimney and the rest as a concrete block to stand the shed on

Had 2 pallets delivered, no issues with the delivery but when we had hand balled them to the back garden and started laying them we noticed there was a variance of all the blocks, the heights had a 5 & 6mm difference which is an absolute nightmare to work with. I should have told B&Q to come and collect them but rest assured I WILL NEVER ORDER BLICK FROM THESE AGAIN!!

My brother bought 3 and we used them with concrete bolts. 1 split from CAREFUL drilling and the other two split when inserting the bolts. Wasted time, caused stress. How difficult is it to quality control? They were still wet inside. buyer beware. B&Q please reject rather than doing this to your customers.

I purchased the blocks to sit 2 water butts, so the height and aesthetics looked good and practical.
2 x flat
2 x sideways at a 90° angle
Paint if required.

Great
