How do I know if I need French Drain?

There are many issues you may encounter that would indicate the need for a French drain system. If you are noticing perched groundwater, this is an issue you must address quickly. Perched groundwater can lead to many issues including growth of mold and mildew in home and building structures, issues with seepage in streets which encourages growth of algae and degradation of crawl space coverings.

Issues with hydrostatic pressure could also result in the need for a French drain, as well as a wet basement or a wet crawl space. Leaving these issues unaddressed can lead to pricey damages due to your home or building structure being compromised.

Additionally, if you have expanding soils, a French drain system is imperative. Expanding soils are ground soils that have the ability to absorb large quantities of water which causes them to expand exponentially, which can produce many undesirable outcomes. These outcomes include structural damage to nearby homes and buildings, and an unstable home or building foundation.
