Building a timber shed on Concrete base without DPM
Posted: Wed Jan 27, 2021 10:20 pm
Hi all,
I am planning to build timber shed towards the bottom of my drive which is concrete and doesn't have a DPM under it. My plan is to build a rectangle out of 4x2 and then use 4x2 cross members to add stability at around 400mm centres then board with OSB 18mm sheets. I want to attach the base to the ground/concrete either by using 4x4 posts and post shoes bolted down however I don't want to raise the height of the floor too much. Or by bolting a timber to the concrete then screwing my frame down to this to hopefully create airflow under the floor.
By building a raised floor will this prevent rising damp or will the timber still suffer from this? my plan is to use treated timber will a dpc help also?
Also I'm thinking to insulate the shed and probably use as a workshop too.
thanks in advance.
