Hi, I'm looking to put a basic timber-framed shed / workshop at the back of my place, and the location means that getting a concreter in to pump concrete for a slab will be nearly prohibitively-expensive. I have a stack of spare pavers and bricks I'd be willing to use as a floor, but wasn't sure of the best way to lay them and what mortar to use so that I could comfortably secure the timber frame. Does anyone have any suggestions? Thanks for your time, Jim
