From what i can see in the photos, they have not gone nearly high enough.
People don't seem to understand that Grout is very porous and the water will actually climb up the walls. which is why you need to waterproof to 1800 as Craig has mentioned.
I would show the builder the photos, and explain that it is leaking. Give him a chance to get the waterproofer back in to rectify the issue.
good luck

looks like they glassed the walls and membraned the base ,this is against the australian standards for waterproofing ,and a call to your builder should alarm him especially armed with photos
