I live in a house that is 100 years old and need some advice of what to do about the basement walls. The foundation of the house is made of stone and brick. The stone wall is about 5 feet high. Resting atop the stone is brick, about 2-3 feet high. The basement is about 100 square feet. The stone part of the foundation seems to be retaining moisture and the walls appear to be wet. Over the years the stone and brick have been deteriorating. Around the perimeter of the basement where the wall meets the cement floor can be found a combination of brick and stone that looks like sand. I live in New England and between the snow and rain, the ground stays pretty wet until late Spring. A contractor suggested I install a sub-floor water pressure relief system that will drain the water table that builds up on the outside of the basement walls. This would include installing a sump pump and piping underneath the basement floor. Is anyone familiar with this type of installation and is this the best option given the cost is pretty significant. Thanks!
It's not the best option but it's one of the more affordable methods to keep a high water table from damaging your foundation.
It is always better to solve water intrusion problems from the outside. However, this will entail digging around the perimeter of the foundation to the footings, applying exterior waterproofing and installing a foundation drain system around the entire perimeter of the house. A good exterior system will also have a method of removing rain runoff away from the house via gutters, downspouts and drains.
