hi, we have a small wooden garden shed on a cast concrete base. the shed is pretty rotten so we want to replace with a larger breeze block construction shed ( that's if breeze block is the cheapest kind of shed to build, that's not wood. [guess breeze blocks will work out cheaper than the pre fabricated kind of concrete sheds you can buy anyway?])
my question is; since i am going to need a larger concrete base, should i smash up the existing one or is there a satisfactory way to 'key in' a piece of new larger concrete base onto to the existing one. many thanks for any advice. yours, john west
