During grading of the construction site, if the slope is inclined towards the walls of your home, then water will get directed towards the basement. As a result, the soil used during the construction process will get loose and settle around your home.
Solution: Fill the slope with a lot of dry sand so that it directs water away from the basement. Once the soil takes place of water, the problem of a wet basement can be solved.
Cracks in the concrete blocks can lead to accumulation of moisture. Also, if floor joints are not properly connected to the foundation wall, it can lead to movement of the wall and allow water to enter the basement.
Solution: You must take utmost care while building the foundation and footings. Also ensure proper connection between the foundation wall and the structure above it. If the foundation of your home is damaged, you must contact a foundation repair contractor and obtain his expert help.
Missing or defective gutters and downspout from the roof redirect water directly to the basement. Also, if a downspout has no extender, then a huge amount of rainwater will be deposited at a single location near the base of the foundation.
Solution: Downspout should be fitted correctly at required places where rain water gets collected. Take care of leakage from downspout using correct waterproof sealers. Extensions, if any, should discharge water at least a few feet away from the walls of your home. If possible, build concrete slopes around the foundation walls to avoid water collection.
Poor Construction of Window Wells
An improperly constructed window well can be the source of a wet basement. It will direct water towards the basement, rather than away from it. It might also lead to a situation of severe flooding.
Solution: If you want to build a window well, make sure that it is covered properly so that it doesn’t allow water to come inside the basement. You must check the cracks in the window well and seal them regularly.
