I wonder how much they are costing. A ton of ballast is normally
£35
to £40.

Peanuts compared to the cost of the chinook, the national reslience
highvolume pumps and the some what larger other pumps that have now
been brought in, and the new road...

Are they actually ballast (as commonly understood), or are some
sand
and some stone?

I'd expect them to be something similar to MOT1 ie a mix of stones
down to dust. Packs together tightly.

You offering to go up with a whacker plate?


The bags may deteriorate when exposed to day light. The dumpy bags
for the slate chippings started to have no strength after a year of
exposure. The bags that the fire logs come do not noticeably weaken
after several years.

I think they'll have to be removed, you don't know whats underneath
or how well bedded they are. The concrete that they are pouring
between them to stabilse the mass might present more of a problem.

Won't they just be left there, and subsequently concreted over?

See above...

Shurely once the damn is emptied to 25% they'll be rebuilding it
properly?

A load of bags of heavy **** dumped from a helo does not sound
like a proper repair.....


Not likely to need rebuilding. It is a very simple construction built
before whacker plates were invented.

So you think a few hundred builders bags of aggregate and a bit of
skim concrete (finished with a wet finger?) is all that will
happen?

What will happen is not the same as what is necessary.
The original dam is made of material that did not need a whacker
plate, the "repair" is totally different...
The core of the dam appears to be undamaged. But no doubt the experts
will report soon. It will be a brave person who says no need to a
rebuild.

Or someone who has no clue...
