How to stop water ingress under house through external brick wall?

[approachmhn]

 The external wall is single brick, I am getting water coming through the brickwork to crawl space under house when it rains .

I can get to both positive and negative sides of the water transfer.

Is there a suitable product to seal the wall on the outside or inside.

the upper part of external wall is rendered. So I think water ingress is through bottom where wall is not rendered and is covered by soil.

appreciate your suggestions

thanks.

Thank you @Dave-1 and @EricL 

Now  you guys gave me more options.

I will start with @EricL suggestion.

@Dave-1 Then  I need your 3rd option to connect to storm water pipe through pit.

Will update as I progress. Thanks again.

Merry Christmas to everyone from the Bunnings family.

@Dave-1 @EricL @MitchellMc  I observed the brick wall has cracks at few places  like the one seen in attached pic.

Is it ok if i waterproof  direct on top of brick ? Or should i patch this and then waterproof?

Also, what cement or patching I should use if I need to?

Thank you.

Good Afternoon @approachmhn 

The bitumen paint will coat everything and seal any cracks. Your picture shows clay below those bricks? Is there a base the bricks sit on? And can we have a long shot (photo) showing the bricks and trench. I am just wondering if you have dug below the bricks and what they sit on.

Happy Christmas as well

Good Evening @Dave-1 .

Thank you. I have got

Concremate at home. So, will fill large cracks with it. Leave half day to dry and then apply bitumen paint. I think that will be ok.

i came home late. So could not take photo. Will post tomorrow morning.

Please check  brick wall photos from negative side. As it is a slope, the slab is like steps. The photo where you see water is on the lower side.

Outer wall where I dug the trench , bricks are actually on a concrete slab. But I see it is not extended away from brick. I mean the clay you see below those bricks is actually  slab made of concrete + gravel. I will post photos tomorrow morning.

it rained a lot last 2 days. I don’t see any water under house. Though there was enough water standing in trench.

Looks like water leak was through bricks.

Sometimes I think, after painting with bitumen, put gravel below bricks and then backfill dirt. 
That might solve the problem instead of Ag pipe. 
Correct me if I am wrong.
