Concrete breaking up in piggery

[Forestlands]

Hi everyone

Have recently acquired a new pig - only one at present, put it in the piggery and allowed it the run of 3 pens and the corridor between them. Not had pigs in piggery for several years put my goats in there in winter. Piggy found some loose bits of concrete, size of small plate, rooted them out. There is some rough bits round the hole to give some grip if I apply new concrete. Concerned that she may root the new concrete out. Should I use some sort of mesh in the holes to give more hold?

All suggestions much appreciated

As long as you clean out the hole and remove all the dust, then putting plain concrete back will be fine. Could paint the perimeter of the hole with unibond or similar pva for a bit of added "sticktion"
