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.

8mm gravel would be perfect, Mahon (@approachmhn).
