A French drain is considered an effective solution for water problems in many situations. In most cases, the major goal of a French drain is to prevent or avoid basement flooding and pooling of water on flat areas such as driveways and patios. This, as seen in the video, ‘French Drain 101 – Everything You Need to Know!’, involves digging trenches to lay a perforated pipe surrounded by gravel.
Using a French drain system may be necessary in some cases but not all the time. Consider a situation where rainwater comes pouring down on a specific area which creates so much water pressure due to being situated at a low-lying position from where the water has nowhere else to go except towards your home’s foundation walls.
Under these circumstances, it would be best to install a French drain system.
However, you may not need to install the system in other cases as there is no proper drainage, and the soil absorbs all the water. In this case, it would be best to regrade your lot so that rainwater can easily travel away from your home’s foundation walls. This involves demolition contractors digging trenches and ensuring that they are deep enough and properly graded on a surface level below where you want them to be.
Factors such as slope and location of the trench play a big role in whether or not effective drainage will be reached. Once done with grading, re-sod your lawn if necessary but make sure only topsoil is used as it holds more moisture than subsoil, which is the layer underneath.
