heres one for you use your concrete mix but add iron filings ,that should get the weight up abit ,we used to use this concrete called rc35 with wire in it to make it very tuff ,but you dont need alot of it we used it for floors about 100m deep,just a thought all best gaz

You must have read my mind, I had a look on E-bay yesterday at some 500g tubs of iron filings, I certainly think adding some sort of denser material to the concrete is the way to go to give it the extra weight.
Thanks for the ideas fellas keep them coming through. happy
