We've had this problem for some years, the water coming through sections of the (outer) wall, blistering the whitewash. With the super-normal rainfall in NJ this year, there's been some pooling on the floor also.
I have a quote from a company called Vulcan out of Newark, NJ to jackhammer a "trench" along the base of the wall, laying in 4" pipe and somehow permitting the underground water to seep in (under the foundation, apparently, though I'm not clear on how it feeds to the piping) and be piped to a sump pump, which they will also install. The pump will disperse the water back outside. They will cement over the trench and clean up "broom clean.". They say this is a time honored technique for alleviating the pressure of the water on the outside of the walls. Their quote is equivalent to $60 per linear foot.
Questions: Is the quote reasonable? Is there a better way to address this problem?
Many thx, Ron
