Concrete sectional garages

My experience only relates to one such building that I bought back in the 70's; they sweat like nobody's business, and I never worked out how to stop it. Sold the property and moved on, leaving the problem with someone else.

Thanks for the comments by all




Do you have any pics of what you have done Kevin? What roof panels do you have I was considering changing it to the anti condensation lined tin sheets and maybe put a bathroom extractor fan in. Do plan on changing angle of roof at some point

I’ve also started lining the smaller garage with more OSBs, and have put up some old kitchen cabinets.

Years ago the council wouldn't give me planning to build myself a small garage in my back garden, so I bought a big double concrete sectional garage for just £1. Then my Dad, Uncle, Brothers, friends, workmates and I dismantled it one Saturday, and drove it all (except for the roof that was asbestos) across town to my place. The following weekend we erected it in my back garden, and roofed it with some used corrugated steel and it looked like it had been there for years. Better still, even though there was nothing there before nobody even noticed my new garage, and twenty odd years later it's still there. As has been mentioned the roof did sweat a fair bit, so I had it spray foamed which not only stopped it dripping on everything, but made it warmer, and more waterproof. Being mostly concrete though, and on a concrete slab it does tend to feel a bit damp inside during the winter months. I put in a log burning stove which did take the edge off it a bit, but in all honesty I think the best way forward would've been to insulate and line the walls too, but I never got around to that.

Mine has the full height vertical sections with 3 ribs, i found that it was fine to drill into the central rib with the depth stop set, its the outer two that have problems with the reinforcing wire causing massive chunks to fly off.

For condenstation I used bubble foil and spray adhesive under wriggly tin type sheets with some success. It reduced the majority of the condensation. I also increased the overhang of the roof sheets and added a dual pitch to the roof which solved issues with mositure seeping onto the floor under the walls.

The first thing is that having been there for that length of time, you would be granted retrospective planning approval, with absolutely no problem at all.  Then as suggested apply to knock it down and rebuild in brick if you so desire.

I can’t remember the costs, but the garages came from a company in Witney, Oxford. The OSBs are 18mm thick. Here’s some photos, sorry for the mess inside😬.
