Palm tree roots lifting brick planter around pool

[Chad(Louisiana)]

I have 3 planters incorporated next to my swimming pool-  They measure about 6 ft wide, 4ft long and 2 ft high-  We planted Sylvester Palms and they are absolutely beautiful- Last year we noticed 1 of the planters raising up on on edge and realized the roots had gotten between the brick and the concrete-  I dug down only to find roots everywhere so I cut them back and backfilled the dirt-  This year it appears the whole planter box is starting to raise and if not taken care of will be destroyed by the roots.  I have a couple of questions 1. Should I just pull them up and plant something else?( if I do that I will have to get a small crane for 1 due to its size and placement).  or 2. Could I re dig down cutting back the roots and install some sort of root barrier?

I'd do #2, 2. Could I re dig down cutting back the roots and install some sort of root barrier?

I think the root barrier is the ticket. I've got lifted decking all around my pool from palms. But, when I had some pavers installed, they pulled out like a gazillion roots and put in a root barrier, and it seems to have fixed it....
