Hello and thanks in advance to any input I may get!

I have a brand new house that wasn't properly graded under the deck that wraps around the whole house. I can't start landscaping because the fill on the outside of the deck keeps falling in underneath. The problem is that the outer wall that encloses the deck is stucco'd already. But i've found a solution to get the fill in without removing the wall.

The water barrier doesn't come up enough on the foundation under the deck and the fill needs to come up 6" and slopped away so I can start landscaping.

How would I go about 'extending' the barrier upward? How do I instal the barrier? What else would I have to do? Can i overlap the barrier so i can build the grade up?

By the barrier I'm assuming your speaking of a waterproofing membrane? If so, then yes you can easily overlap more so as to raise the grading. You will have to purchase some membrane and cut it to the size you would need. Make sure to leave an overlap at least 6" or more to the existing membrane, and attach it to the foundation by either a hilti fastener, a ramset fastener, or by using concrete anchors. Before attaching the edges and the top, apply a water-resistant tar.
