Jake, it's important to keep in mind that the installation of the CBU and the installation of a direct bonded waterproofing membrane are two separate and distinct steps and you need to complete one before doing the second.

The CBU manufacturer will specify the treatment of the joints in the CBU panels, usually requiring the use of an alkali-resistant mesh tape and thinset mortar on all joints, including the changes of plane. Only when that is completed and cured will you apply a direct bonded waterproofing membrane following that manufacturer's recommendations.

You wanna deviate from that you're on your own in determining what will work effectively.

Never heard of that fabric you linked and can't comment on its properties, good or bad.

My opinion; worth price charged.
