Hi All,

I'm hoping this is in the correct section.....

I have fitted some folding sliding doors to the rear of our house. The top of the bottom track is flush with the floor to allow wheelchair access so, the bulk of the bottom track is set into the floor. At the moment there is an old conservatory on the back which will be coming down in the spring. I feel I need to seal under the bottom track (it is sat on a damp proof coarse) from the outside to stop rain water seeping in.

What is the best method for this ? Silicone or expanding foam or something else ?

Cheers.

Sillicone!
