Basement water seepage can be an ongoing issue that becomes just an accepted fact of spring. Water from saturated ground can find its way through any crack or seam in a basement floor and foundation. It can even soak directly through concrete. If rising ground water becomes trapped, it can build "Hydro-static" pressure, resulting in cracking and heaving.
There is a multitude of suggested solutions out there; But the most reliable and time tested is an Interior Drain Tile System. If installed correctly, it can permanently prevent basement water seepage. Below is demonstrated, the various ways water can enter a basement and why certain approaches don't always work.
In-Home Radon Exposure can be a serious concern. According to the EPA, it's the number one cause of lung cancer among non-smokers. Radon originates from deep uranium deposits. As it's released from the soil beneath our homes, it becomes trapped and accumulates. When inhaled it releases Alpha, Beta and Gamma radiation directly into the lungs. It's similar to receiving chest x-rays. There is no proven safe level of exposure. Whatever your radon level is, you want it to be lower. The Upper Midwest has some of the highest radon levels in the nation.
In most cases a radon mitigation system can be installed quickly and at a reasonable cost. Not only will a good mitigation system reduce radon levels, but it can reduce water vapor intrusion possibly eliminating the need for dehumidifiers. It may lower other soil gasses as well, such as: methane, hydrocarbons and other contaminants. According the the EPA, the most effective mitigation method is Sub-Slab Depressurization. And sub-slab depressurization is especially effective when incorporated with a drain tile system.
