Legin,

Apols for the duff line lengths - having a bit of a
problem with that today..

Also - thanks for your post - It made me go back
and check everything.... It really is quite a complex
problem, although you wouldn't think so from
first appearances.

Anyway - it will be interesting to see what the
boss man will say - currently he is imobile with
a back injury (not nice) - so it will have to wait
for a bit.

get some acro's on monday, take the wall down, replace the lintel, rebuild the wall
with the correct blocks only vertical this time, with no curves, as it ought to be.

knock the materials and your labour costs off the 'builders' bill + 10% for being cheeky.

you have photographic evidence of the wall, the builder doesn't.
