Dilemma - Dug trench now foundations are exposed?

[InspiredSloth]

Hi all,

 

I dug a trench around the back of my house as I was recommended it by a damp specialise as the pavement water was splashing above the DPC. 

 

I have done this now and the foundations are exposed causing leaks through the ground concrete floor. 
 

I was planning to fill with gravel (as advised) but my worry is that the water will then still sit on top of the foundation and wall.

 

i have considered a perforated pipe and connecting it to the drain but the drain is cast iron and there is an old dead gas pipe in the way, which I did not expect to see so high up. 

Can anyone guide me to a solution here? Appreciate any help in my dilemma 

 

Thank you

I don’t see how digging out like you have would cause leaks in your concrete floor? If anything any water would come out and pool in the bottom of the trench.

 

I did the same dig out when installing external wall insulation and didn’t have any issues.

 

what makes you think this has caused it?
