I installed this material on my new home 4 years ago.
Victor's explanation of how it is to be installed with the silt screen on the outside and the dimples against the wall is correct.
The mat only helps channel water to the drainage system. Otherwise, it does nothing for water proofing a wall. It should be installed with an adhesive.
The builder wasted a lot of money on installing the mat "wrong side out".
I would report this to my client and recommend correction, as costly as that may be. In addition, if the builder got this wrong what else did he miss?
I think this materal works very well when correctly installed. You can place this over any other coatings you have applied.
Another dumb builder story.
