Don't bandage, treat the drainage issue at the source

Situation: Client had been talking with 2-3 different companies to resolve their drainage issue. Essentially, where their basement which was once dry, now happened to take on water in the past 3 years. The neighbor was identified as potentially diverting drainage water down the hillside into the client's property.

We arrived on a rainy day to observe. We made the conclusion that it was not from the hillside/neighbor as the rate of water accumulation was not consistent with surface water runoff. Judging by the way the water welled up in hole, it was determined to be groundwater. The root cause as to why there were groundwater issues now versus a few years ago was not definitively identified. However, with the amount of construction which = compaction ongoing in the area, we surmised it had diverted the underground water channel towards the client's home.

Previous contractors had simply suggested installed a sump tank in the basement and breaking the concrete after the water had entered the building, but since we could see where all the water was coming from, we instead installed a water pit with sump pump which fed into the existing French drain. This saved the customer $$ thousands as we did not have to break up concrete inside and run a large amount of piping while also requiring them to constantly monitor for mold issues inside the home.
