Cant believe I completely forgot about that after only just smelling it being done on site the other week.

Do you think thats goo enough ?

And is there a specific type of stone I should use to fill the trench ?

First of all where is your damp proof course?
There should be a layer of plastic or something in the bricks to stop water wicking up the walls. If its raining the ground is going to be wet there is nothing you can do about that that's what the dpc is for protecting your walls.
The holes all drilled in your wall looks like someone tried injecting silicone or some shit in to act as a dpc but usually it's done by cowboys to combat damp that is caused by something else because it doesn't really work anyway.

You can put gravel in there, smaller the better, that's why they use sand in sandbags. You can put in edpm damp proof sheet plastic stuff but usually it's not uv safe so it will turn brittle and rip easily if you leave it out on the sun. Not a problem if you cover it with gravel and shit.
Ideally of course you would lift the bloc paving and whatever the sub base and laying course is made out of and put a proper fall in the sub grade to allow water to run away from the house.
If its impermeable you should ensure where your drain can handle the extra flow

Does this plastic go on the outer wall ? I've seen a netted plastic with dpc kits for the internal wall.

The holes covered in mortor was the old dpc the little holes at the bottom are done by me.

A few people said to me (who work on my construction sit)that I should just buy that kit inject it into the mortor,dig a trench and render the internal wall with a. Waterproofer.

I feel like I can't remove all the block paving yet as I can afford a skip and don't have a car to take all that stuff to the dump.

Just digging out that trench took up about 6 Bing bags.

are you wanting rid of the block paving?
put it online someone will take it for nothing.

the plastic with the kits is to tank the wall on the inside because of how shit the injection is it doesn't stop the damp coming in.

have a read of this http://www.pavingexpert.com/dpc01.htm.

dpc could just be engineering bricks, should be fine if you assume dpc is just under air brick leave enough of a gap.

probably someone put this block paving in without considering the height causing damp inside, whoever was called in just drilled, filled collected and bolted before anyone realised they hadn't addressed the actual cause.

just keep it 150mm/6inch below bottom of the air brick you'll be fine.

It's not just the blocks what's the problem it's all the soil what I would need to remove as well.

And yeh I got told it was just someone cowboy following orders.They wanted the garden that way and that's what they got.

I was actually looking on replacing the air rocks as well but I'm thinking that's over kill
