(For my old mate Kevin Blackburn)

Bentonite is magic
When mixed in slurry form,
And injected into apertures
Where earth worms are the norm.
The slurry forms a barrier
Which holds the concrete, wet,
Quite apart from earthen surfaces
To give exactly what you get.

YOU GET NO CONTAMINATION
YOU GET CONCRETE DRYING CLEAN
YOU GET SMOOTH GREYISH SURFACES
WHICH COULD BE PARCELED TO THE QUEEN!

So when constructing tunnels
Or massive footings bare
Or reinforced deep piling
Which extends way down to there,
You MUST pour in the Bentonite
In slippery, slurry form
To keep the concrete looking
Sparkling clean, as is the norm.

Then....
YOU GET NO CONTAMINATION
YOU GET CONCRETE NICE AND CLEAN
YOU GET BEAUTIFUL GREY SURFACES
SHINING BRIGHTLY FOR THE QUEEN!
