Along with four bags of cement for each bulk bag - So 8 in total.

Another two bulk bags of crushed brick/concrete or MOT1 for the sub base.

Thanks. All came to £90 now. Looking at Jewsons. Got 5 piece 3m long timber 100x47mm , 4 bags cement, 4 bags of bulk and 1 bag sub base. Do I need to add anything else please as apparently free delivery for orders £100 or over. Thanks

I'd get a couple of lengths of 47x47mm timber to make some pegs to keep your forms in place.

Just wanted to say that I'm following this with interest, and hoping it all goes well. Do let us know how you get on, and post some photos.

Thanks. It came to £371 now 😲 Is that sound right? Didn't think it was going to cost that much. I added 10 pegs too.

We can shave a bit off that for you...

https://www.jewson.co.uk/p/pefc-sawn-carcassing-treated-green-150-x-22mm-PZGF229C for your shuttering..

https://www.jewson.co.uk/p/fsc-premium-kiln-dried-regularised-c16-treated-carcassing-100-x-47mm-FBJT4710 to use as a straight edge to tamp & level the concrete.

https://www.jewson.co.uk/p/sawn-roofing-batten-blue-25-x-38mm-fsc-SBBF2538 for your pegs. Cut your own, and it will be much cheaper.

If you pay a visit to a Jewsons trade counter, you may well get a bit of discount on the prices. For example, tell them that B&Q can do cement for £4.02 a bag, and Jewsons will probably price match. If you mention that it is for a sensory room, they may well take a bit more off the total.

Best to have 2 people for the tamp as it's a 10ft span. One on the mixer as well would be good.

I have nothing useful to add to the great advice here, but I just want to say how refreshing it is to read a thread where the OP  decides to go for it, rather than despairing that they can't 'get someone in.'

This ^^^^^.

This thread is a credit to the OP and everyone who has pitched in with their help.

Go for it OP, and good luck!
