I am dealing with a customer who is pissed off , its a waterfront house , took over 1 year for permits ,problems with ground water and  prices went up for him during that time , and the above average rainfall in Maryland has slowed things down .  

We are doing a green concept that will use solar energy, geothermal HVAC, and ground water technology.

They make handy storm shelters, among other uses.Basements are holes in the ground, and therefore are susceptible to flooding from rainwater from above and groundwater from underneath. 

We have been painting ours with paint designed to help stop ground water from leaking in, I would think that if the wall is in decent shape you could try something like that.

Ground water, that was the problem with the house above with the TWO sump. 

One big issue is the ground water , we dug a test hole for footers and its too wet , so the engineer has to come bask and design engineered footers

in CA, Rotten Robbie seems to have a track record of buy contaminated smaller station, working the the remediation process (can take years w/ groundwater contamination), and then remodeling them with a large c-store.

It looks like it might have been an issue where the sump pump electrical breaker flipped in the panel and stopped working.I'm still unsure about where the leak was (pipe or ground water) but I'm hoping to find out soon.

Check for past ground water intrusion along the footers and wall as I find it unlikely there were pipe leaks that caused mud to form above the vapor barrier.

Given the location, you might need a Phase I to check the potential for pollution or contamination of the soil and/or ground water.
