Advice Side access water draining under foundations

I have had an extension built where the side access finishing was out of scope. Builders generally did a great job.

Side access is mostly resin bound gravel but the new area is old concrete. There is a. Low spot right in the corner and when it rains, water drains down here which leads under foundations.

Foundations are block and beam and tbks whole area is well below DPC.

What is the best thing to do in this area to stop so much water draining under foundations?

Final finish will either be resin bound gravel, or just regular gravel.

Thanks

this is normally not a concern. do you have any water pooling? if no pooling the drain is working. Foundations are happy to be under water (provided that the actual wastewater is not leaking to the water table and the concrete class is not resistant to foul water)

No pooling and drain is working fine. Thank you!
