Situation: Purchased a house a year ago from an owner who knows nothing about it (rented out, moved away, etc.). Crawl space with outdoor air ventilation, one-story house built in 1991.
Problem: Water intrusion in the crawl space during heavy rain. Upon inspection, I see that half of "one half of the roof" and an extension of about 60 sqm drain into the same storm drain, through a somewhat unusual pipe routing (downspouts and gutters as per the image) . In this spot, two large metal sheets have been placed (see image) to manage wastewater (I assume).
Since I'm coming directly from a rental and have previously been actively uninterested in all of this, I'm not quite sure what to do. A dehumidifier is installed and maintains acceptable moisture levels, but it runs around the clock all year. Plastic sheeting on the ground is not turned up against the sides (foundation wall?) in the crawl space. Minor growth is present on the floor joists, but random moisture measurement with a "pricking tool" did not show alarming levels.
- Are these sheets an acceptable solution?
- Would you have re-drained? In what way? The entire building or just where the water intrusion is most severe?
- Would you hire Avkem for the growth?
Thank you for the help in this matter where I am quite lost.
The question is if the pipe that's under swallows the water... start by checking that...
Then there are nicer solutions but this one should work
how do you mean by checking it?
I find it a bit strange with ground sheet as drainage. Usually, it's deeply located pipes, fabrics, etc. Is this some afterthought fix by a DIY enthusiast, or could it be a standard made by professionals?
Probably, the leaf debris doesn't swallow the water from two roofs and overflows.
Then they have probably placed the plates for it to run away from the house.

The easiest is to put on rain gear during a heavy rain...
well... that wasn't done by someone with knowledge, let's put it that way..
More like a quick solution
Why not try extending the downspouts from the extension towards the lawn to see if the stormwater pipe can handle the majority of the roof without overflowing?
