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?

You want to drive rain away from your walls. 
 

Waterproof layer then a dimple membrane and french drains to get water away. 
 

Dorken or permaguard websites can give you more information. 
 

With that digging and opening up, your walls should dry out completely.
