I have a 10 x 20 raised concrete slab (currently our front porch) that leaks into the basement area beneath. The only way it could be fixed was to apply EPDM rubber w/ adhesive.
Now we'd like to put a treated deck over this. We have the capability to sink corner supports at the outer corners, but would like to not drill through the EPDM if at all possible to anchor the decking. We can however, attach something to the house. The only other problem is that we only have 2" to work with from the concrete slab to the bottom of the door. Any ideas would be appreciated.
