pouring concrete pad stones

[mcluma]

I will be pouring a number of concrete pad stones in situ

These pad stones will be according to the building inspectors spec, however, what is the best way to do it, make the pad stones at perfect height so they will take the RSJ and are at the perfect height, or do I make them about 10mm lower and pack the RSJ with a dry mixture of cement, so it will sit at the perfect height (also knowing that concrete shrinks when drying therefore achieving the perfect height is difficult)

Your help/comments are appreciated

You put your shuttering at the bearing height required, and level the concrete off

Why are you going through this palaver, instead of just building the pads in solid blues, cut lintels or buying some padstones for a few quid - less than the time and cost of shuttering?

By pouring the pad, there will be a better weight distribution over the existing bricks,

Really?

Better load distribution than a fully bedded padstone, and so much better to warrant the messing about?

Perhaps not so better if you don't get all the air out though, or if the bearing face shears

^woody^ if you put your mind to it you can accomplish anything.

Some idiot has gone and cut the padstone down to accommodate the wall plates!

Correct, building inspector was fine with that

He was not overly pleased with them

Bet his back wasn't, them things belong below waist height.
Great fun over the lintels I see

Interesting bond over the windows

I wonder if there are any implications of a padstone bearing on only half the width of a block rather than spread over the full width?
