I am building a new shed this weekend, its going to be a Biiiiiig shed, 5m x 4m ;D ;D its going on a old concrete pad thats been up the back of my garden since I moved here 20 years ago, The shed will be constructed from a steel foam sandwich used in the construction of warehouses, and comes in 6m lengths,x 0.9 high, its about 80mm thick with tongue and groove top and bottom, so in effect its interlocking, held together with sheet metal screws, My problem is--- I'm going to put a 75 x 50mm external treated wood lintle on the floor to mount the first run of sheeting onto, this will be bolted to the pad, what can I use under the timber to stop water running under it and into my shed,  ? Ian ;D |

If it was me i would put a row of bricks for the first row.Then fix the wood to that.Keeps the water off the wood.

I agree, i have one of those log timber garages, brilliant really but nothing seems to stop the water coming under if its heavy rain. If i did it all again bricks would be my first choice as the first layer.

At work we have drop over canopies that go over our gensets. Ideally we cast the interior section of the slab an inch higher so it keeps water out. On flat bases we use a bitumen roll arrangement, bit like a tarred roof that mostly works.
But yeah bricks would be best. If you do use wood remember to put a roll of damp course or similar under it so it doesn't sit directly on the concrete and rot away. If you used a shed load of silicon or similar both side of the damp proof I think you'd have a fair chance of keeping it dry. Still get a problem on the doors of course unless there's a threshold strip.

From experience I'd go with what people say, a row of bricks or blocks to start with, Both to stop leaks and because wood sat on the floor wont last long!

screw a creosoted [or similar] 3x2 [75x50 in old money] to the base with good 4"[100mm] screws cut a 10" approx strip of roofing felt ,nail it on top then hung over the side of the slab, then screw the panels down to that sandwiching it, very effective , also provides a run off for the panels, be careful using only the panels as a structural unit , they can sag and move about if not fixed to a separate structure, good luck

Another one saying bricks here!
One course of bricks at least. Idealy the timber starter plate should be at least 100 mm above external ground level.
