Blue Circle High Strength Ready Mixed Concrete 20kg Bag

Q: Can this be used as a foundation for a greenhouse. If so can you use like postcrete and use several bags at a time before adding water

It drys underground and you can use it as a base layer

Q: I'm looking to fill a 70mm deep hole thats around 3 foot wide. Worried about cracking. Anybody filled just as deep as this?

Yes it is fine I used it for that on the drive way so i could put a motorhome on the drive and its fine

Q: Could this be used for casting a counter top?

In theory you could use this as cast medium but it wouldn't last long as a counter top. Although very strong it will not withstand a heavy load unsupported in the form of a beam. Answer; use reinforcing mesh, in a box mould with the reinforcement placed in the middle, it should work. Very hard to finish and heavy, by definition it will be thick; you might need brick base units, interesting project though.

Q: can i use this to repair concrete curbing set- will it 'stick' to existing concrete?

I used it to repair an existing area where my bins go and it worked well for me.

Good but far cheaper from a builders’ merchant

This is good stuff, just add 2 litres of water and mix. You’re just paying a lot for free delivery as from a builders merchant it’s £7.50 per bag

Cement for DIY novice

Initially was a bit skeptical about using a ready made mix. But once mixed - it looked similar to the cement we were replacing. The stones in the mixture will help to make it rock hard when set. BTW, cement seemed to set after an hour.
