In our youth
“cleats” might have been the round “grabbers” on the soles of football or soccer shoes.

the meaning of “cleat” here
is like the downward crossways bars on bulldozer tracks

these cleats “grab down into soil” and resist slippage
of both bulldozer tracks
and in the future your “driveway” which is just a wide concrete “trackway” that never is supposed to slip or move.

e’j
or e.j.
is short for “expansion joint”
- the narrow slots running left to right in the driveway
made either by the original wood forms for concrete sections,
or sawed cuts
that are filled with caulking over foam,
which exclude unwanted ice,
or block toothpaste like mud flows from underneath.
