Cracks and spaulding developed in the curbing near where I work.
Workmen came out a month or so ago to make repairs,
They semi-carefully cut the damaged concrete curbing away
with diamond-tipped saw blades, then filled the
resulting gash with of mending concrete.
Here, against the older and new bits of yellow paint,
the triangle helps to create both a bit of tension
and attention for a bit of curbside art.
The repaired bit shown below was done
several years ago. The workmen either realized
the triangle would make a stronger repair,
or that two cuts only made for
a quicker job, requiring less work.
