Foundation 2 ply waterproofing membrane not affixed to wall
We had serious exterior waterproofing work done in 2012 at major cost. Lamentably, we're still dealing with crawl space water in heavy rains. The downspouts have extensions running more than 10' to side. Grading is next on my list.
Below is a photo of the 2 ply poly membrane placed after tarring walls. It's all over the place in differing heights, but not secured. In some areas it's very low below the ground, in other areas it's slightly above the ground and has serious dirt caught both immediately next to the foundation as well as between the first and second layer. Clayish dirt.
Wasn't this membrane supposed to be high enough so as to secure it to the foundation wall with a deflection for the water and some mastic or other? The way it is now, the water runs down between the membrane, pushing it against the foundation.
Thanks for your advise on what to do here. How do I manage that unattached waterprooofing membrane when we have it properly graded in short order?
Membrane here is about 3/4" above ground.
XP in landscaping due to time.
