Thread: Shed lining & moisture

I would not worry too much about it drying but if you have time no harm done. I would likely seal the external sheets to the concrete to try and prevent vermin and other pests.

As for moisture rising from the slab you should have a damp course under your wall.

What DaveTTC said.

I used thick foam strips cut to fit the colorbond profile to seal the bottoms of my shed (available pre cut from roofing suppliers). It keeps the snails and blue tongue lizards out of my shed.

Black PVC damp proof course is cheap as chips. I would make sure to leave enough sticking out from the inside edge of the bottom plate to run under the skirting as well.

I've spent a lot of time thinking about sealing the gap between the slab and the Colorbond. I'd considered the expading foam and Vermaseal but have abandoned both ideas. The foam strips you mentioned, they sound like the stuff I've seen at Bunnings, about an inch or so thick. I thought they were meant for using where the roof meets the walls. Are these the same things? If they are that sounds like a very easy job. I imagine that you could just "squash" them into the cavity and wouldn't need any glue.

I've just started googling the dampcourse and I like the sound of it, will definitely do.

Hi Arch

The foam strips are the same as the ones you have seen at the big green shed. The are cut to fit the underside profile of the colorbond sheets which in your case will be between the edge of the concrete slab and the inside face of the colorbond sheet. No glue needed, just push them into place and they are a perfect fit. I found they were cheaper at the roofing supplier than the big green shed.

Hope this helps

This does help, thanks.

Arch,

Just as twosheds said...the foam will keep snails, lizards etc out but if you get a mice problem, they will eat straight through it. I've seen them eat through plaster walls

Could be time consuming but possibly add patches of chicken wire ...same profile as the gap/foam but just a tad larger and press them to the bottom with the foam pieces.

I would definitely be putting vermin proof mesh down to keep rodents out of the cavity. I have just had to strip the lower gyprock lining in my shed to get in and clean out the stinking mess the rats have made in the little cavity runway between the concrete and the first purlin.
