A few weeks ago my basement flooded again. Oh, the woes of home ownership! The Washington D.C. Metropolitan Area had over 63 inches of rain in the last year. Ground water and water tables persist in Upper Marlboro. Water seeps in from under my basement floor where it meets the foundation footer. The french drain (gravity flow system) I personally installed in the front yard didn't seem to solve the problem as the ground water made its way to the front wall of the basement.
So, I decided to hire a local waterproofing company. They did a great job and gave me a fair price. Ask me how much? The labor costs are the bulk of the job. The contractor had to dig a channel (trench) around the perimeter inside my basement, alongside the footers. PVC pipe was then installed in the newly-made channel to allow the flood water to flow into a sump pump basin, then pumped outside of the house.
Here's a video I made of the project..........https://youtu.be/JXV3abLlago
