My house has a daylight basement along with some areas that is finished crawl space. Basically instead of dirt there is slab in the crawl space. I bought the house a few months ago and the crawl space looked super clean. The inspector did call out was one small area about 2-3 feet where there was some moisture and efflorescence. See below
Last year my area had the highest rains in years and hence, the seller believed that there was moisture. He mentioned that it had never happened earlier and there were no other indications in the crawl space. The seller put hydraulic cement in that area (in the internal part of crawl space). I bought the house thinking that it may not be a problem again. However i have been concerned and hence have been keeping an eye on the area especially after the recent heavy rains. Lo and behold one day i see the hydraulic cememt darker in a couple of very small areas. I did not see water but the dark areas indicates moisture. Now that those areas are becoming dryer i think i see efflorescence.
It seems like the hydraulic cement is not helping. Also seems like i may have to get a professional but I am not sure i can afford any work now.
My questions are:
If the problem remains contained in that small area or repeats at a much lower frequency (1-2 times a year), do i need to resolve this problem immediately? I understand that if this spreads or keeps on happening than i need to get it solved. How worried should i be if it remains in that small area or happens very infrequently?
Can I do anything from inside. like applying another material to prevent water from seeping? The hydraulic cement is not 100% as can be seen above.
It seems like the proper way to fix this is to get a contractor, who will dig from outside and build a solution to keep the water away from the foundation? What is the approximate cost I am looking at here. Talking to a friend at work, he said it could be easily 5K.
Any other thoughts or help ideas?
I posted the inspectors picture in the my post above. Here is the latest picture after the hydraulic cement and efflorescence i saw few days ago. Is this minimal. This is about a 2.5-3 ft
