Is there any other fix other than complete replacement?

From contributor A:
Is this happening in the shop or after installation? If it is after installation and you are using a contact adhesive, I have seen a perfectly filed edge grow past the face or self edge grow and then chairs and such catch the edge. For the above to happen, the site conditions are varying, causing the laminate to grow.
From contributor P:
It might be a chair somehow raising in the area, although typically that is on the bottom side. The laminate will grow usually in humid weather. The only solution I know of is to file it again.
From contributor K:
It is not trimmed close enough. If you have just a touch of overhang, it is easy to get it chipped like that.
From the original questioner:
Thank you - I appreciate the answers. It sounds as if the filing is the issue (or lack thereof).
From contributor Q:
This can be the nature of the beast with plam tops. We have gone to 3mm banding on all plam countertops. When the customer requests plam edge we explain and politely decline. The call backs simply are not worth it. We also use a press to lay up all sheet goods. No contact.
From contributor G:
Is the laminate growing as suggested or is the substrate shrinking?
From contributor J:
You may want to store your substrate material in a very dry location before the laminating process begins. I have also, when concerned about shrinkage or expansion, sealed the substrate material thoroughly before use.
From contributor N:
Insufficient bond at edges possibly? To the left of the chip there appears to be some fibers in between the top laminate and the edge laminate as if somebody's clothes may have caught some loose laminate. Maybe not full replacement but it'll have to be re-laminated.
