The strip mall down the road recently sprouted ersatz stone pillars around the steel posts holding up the roof:
Six days later, more slabs have fallen off the first pillar in the row:
And the second pillar:
Those fancy(-ish) bases consist of a wood frame covered with a mortar layer holding tiles of imitation stonework. From what little I know of stonework, mortar works only in compression, so you can’t glue tiles onto the side of a concrete lump using mortar.
Epoxy, maybe. Silicone snot, probably. Mortar, nope.
This happened barely weeks after the project’s completion, so I foresee poor ROI for the mall owner and plenty of warranty work for the contractor.
