Planning to install a conservatory on a concrete slab, but what should be used underneath to prevent moisture from seeping in? Should a flashing be placed around the slab to mount the tracks there? Or is a sill a viable solution? Or should it just be screwed in at the edges and sealed with caulking all around?
Doesn't cost many kronor to get bent from sheet metal, 150:-/m maybe.
I usually glue the sheet metal in place, and then a joint between sheet metal and rail. Sometimes I fasten with a sheet metal screw.
It all depends on the system.
I have installed plates, similar to window sills, with the surface bent up at the back edge. Lightly glue to the concrete, then a little extra glue/silicone under the sliding door track. I also put some screws and plugs into the concrete.
Depending on the type of Willab section it is, some should be fastened with screws in the bottom rail while others should not, as specified in the installation instructions.
When we mounted our sections, I used a bent aluminum sheet that went under the first profile on the section's frame and is bent up as far as the frame profile allows. Sealed with sealant between the aluminum sheet and rail, and with foam between the rail and concrete. The bent aluminum sheet is only held in place by the sealant and the weight of the frame. Our rail was not to be screwed down as this would affect water tightness. Our section has a frame all around and a thermal break. It might be that sections with a thermal break and frame solution should not be mounted with screws in the lower rail, but that's just my guess....

Wg62eco is what they're called. I hope the assembly instructions will be included with the delivery, then I'll see how it is with these.
Hijacking the thread as I have the same question. But in my case, the slab is larger than the actual conservatory. I'm a bit worried that if I place metal under the track for the sliding doors (Willab Garden WG 62 Eco) there might be a slight slope backward, towards the actual track. What do you think, is it enough to have a line of sealant to prevent water from seeping under the track?
