Problem is though, he's right, when you put something on them shelves, the outcome is not looking promising. Imagine right, your partner walks in there, something cracks her on the head, how you going to explain it to the old bill. Well, like, I had these 1980 brackets, and a couple of pieces of old mdf, just slung them up there guv - I wasn't to know the middle was going to cave in, like her head. Nah mate, the police will look you in the eyes, and they'll say, really, how thick are you?
really came down to logistics ie how close the jobs were to our concrete plant. the hardest thing is making sure you send the right mix
Couple of bits of old mdf? Looks like he’s been and took a couple of doors of an old wardrobe down the tip. @Commachio unblock Sucky look at his DIY ffs.
any concrete thats above 20 newton thats been air entrained and mixed with fibres should do the trick , but id go with an RC45 personally
