The foundation of home is where a house meets the earth and becomes one with the ground. Made of cinder blocks, bricks, concrete or even wood, the house is placed on a foundation to keep the actual house from touching the soil or ground. The foundation allows space under a house so that the inner workings (plumbing, electricity, A/C, cable, etc.) can be accessed by either the homeowner or a professional home repair worker.
The foundation itself must be structurally sound so that the physical house will be able to withstand the continual onslaught of Mother Nature. By allowing air to flow under a house and around its’ foundation, the material of which the foundation is comprised will be able to perform to maximum efficiency. We don’t usually think about the foundation of a house “performing” but performance in the case of house is simply maintaining integrity, i.e. ability to keep the house upright and functionally sound.
Moisture, from clogged or improperly installed gutter systems often leads to the formation of mold and will thrive in the dark, dank atmosphere of a foundation. People have tried for years to combat this inevitable problem by temporary measures or so-called solutions that do not work or simply will not do what the company said that it would. Sub-pumps are popular as a temporary stop-gap measure that simply prolongs the problem eventually maxing out the capacity of the sub-pump allowing unwanted moisture to seep into and inevitably flooding the basement or crawl space. However the best solution to prevent foundation cracking in the first place is by installing and maintaining clean gutters.
The foundation is then weakened by the moisture that softens the dirt or earth, or even worse the actual integrity of the foundation itself, causing vertical cracking of your home.
