The landscaping design calls for several feet of thickness of soil on the exterior side of this wall. 
No serious thought has been given to this wall design. The contractor did not take care either.
The concrete backup wall is carelessly coated with liquid waterproofing but voids are left.  Masons started filling the cavity with grout [read: dumped old, partially cured mortar and debris].  No continuous thru-wall flashing has been designed nor installed.

The proper design should provide a right waterproofing consisting of a moisture barrier and a thru-wall flashing leading water outside to the drainage line and a drainage line with a working outlet to the sewage system.
