RiffRaff Posted July 17, 2016 Share Posted July 17, 2016 New shed being delivered soon. Flat concrete base already down. From the photo's, the shed floor has 'joists' underneath, running from front to back (6'), but appear to be only (maybe) 1.5" square. I have some 2x3" timber lengths that I could run at right angles to the shed joists.... Should I, or just simply position the shed on to the concrete?!

Thorpist Posted July 17, 2016 Share Posted July 17, 2016 Definitely lay your hut onto wood, over time the base will rot and can be replaced easily. Link to comment Share on other sites More sharing options...
Obelix Posted July 17, 2016 Share Posted July 17, 2016 Either impermeable "blue" bricks and rest on them, or as you say crosswise planks for the reasons Thorpist says. Dont be shy with the creosote either. Link to comment Share on other sites More sharing options...

Daven Posted July 18, 2016 Share Posted July 18, 2016 (edited) Did your last one burn down ? Do you live in Fulwood ? Edited July 18, 2016 by Daven Link to comment Share on other sites More sharing options...
RiffRaff Posted July 19, 2016 Author Share Posted July 19, 2016 Did your last one burn down ? Do you live in Fulwood ? (1) Thankfully not, and (2) unfortunately not, are the answers to your (strange) questions! Link to comment Share on other sites More sharing options...
spilldig Posted July 19, 2016 Share Posted July 19, 2016 Definitely lay your hut onto wood, over time the base will rot and can be replaced easily. one neighbor of ours had a shed built on a concrete base in the early 1960s. The shed went rotten and was demolished in the 90s. The concrete base is still there as good as new. Link to comment Share on other sites More sharing options...

The concrete base is still there as good as new. Hence my question : and there's the quandary! If I simply lay the floor as it comes - on approximately 1" bearers - rain will get underneath, sit on the concrete, and start rotting the bearers! If I raise the floor on 2"x3" cross-bearers, the theory is that damp will have to 'get through' them first before getting into the floor proper....that said, the more space there is underneath allows wet leaves etc., to get underneath as well! The waterproof brick idea mentioned by my friend above is a cracking idea, though... Link to comment Share on other sites More sharing options...

The waterproof brick idea mentioned by my friend above is a cracking idea, though... Yes indeed. Unfortunately I don't know anything about the construction of the shed that was there except to say that the concrete base should outlast the shed, but I wish you good luck with it.

Janus Posted July 19, 2016 Share Posted July 19, 2016 (edited) The greater the airflow under a shed the better it is. A good size gap underneath will deter rats from making a home there. When I prepared a base for a shed some ago I put 3 old railway sleepers down with a breeze block under the ends of the sleepers. No rats, and very good air flow ventilation. You would be fine with just the sleepers though. Edited July 19, 2016 by Janus Link to comment Share on other sites More sharing options...
