Temperature plays a huge role when it comes to water because moisture has a huge impact on basement walls. Moisture is directly affected by temperature; it is based on temperature change, inside and outside the house. Living in the Midwest temperature changing seasonally needs to be taken into consideration. Materials expand and contract when the weather changes from hot to cold. Snow melting causes huge amounts of water at one time; it is like a rainstorm for weeks. All winter long the ground is squeezing the basement walls like a pop can. Soil has no memory and will not go back into it original position. If the saturated soil slumps and breaks through the wall, when it gets warm the soil will not contract and go back to it initial position. It will continue to bow the walls until the pressure is forced back onto the walls opposing the outside force. With the temperature and wind speed figures a homeowner can account for the natural changes that occur when the weather seasonally changes. Taking all these factors into consideration helps to make a more realistic solution.
