Hi Everyone-

I’m in the planning stage of adding and extending decking to a front porch.  Currently the “porch” is a 36″ X 144″ concrete stoop.  I’m planning on extending it to 96″ X 144″ using TImber tech.  Currently there is 2″ of clearence between the top of the concrete and the bottom of the door so I can’t build up the height of the deck beyond the 2″.  I was planning on drilling lead anchors into the concrete and then screwing the deck boards down into the anchors.  I have used this process in the past (using cedar) with good results.  This is a total PITA to get everything lined up so that it looks neat.  I was wondering if anyone had a better solution, especially since I’m using Timber tech Earthwood.  Their specifacations call for 1-1/2″ air space minimum.  I can’t build any more than 1/2″ of air space.  This area has a roof and will fairly protected from the sun which should help.

Thanks for your help.

Brian
