The pergo floor i have shifts from front to back - like when the kids slide or stop quick on it some of the individual panels shift about an inch.
Is there a rubber compression piece to install to the front or back?
I know the side to side is for the buckling and have seen it on my friends floor - no problems there.

Well I went back to Home Depot and got the glue.
I removed the molding around the sides.
Opened up the gaps and put the glue in.
Then put put the gaps back together. Using a flat faced pry bar to get the gaps tight.
I rubbed the excess glue off with water and a cloth. Put the moldings back in place and now will see how it holds up.
