Hydrostatic Pressure Relief System

Think of groundwater like a river– it flows from areas of high pressure to areas of low pressure. When it hits your foundation, it wants to keep going, but your foundation acts as a dam. The pressure that builds up is called hydrostatic pressure.

Most foundations are made of concrete, which is porous. This means that when hydrostatic pressure builds up (after heavy rain, for example), it starts to push water through concrete and into your basement and basement walls. If you’re a homeowner noticing damp smells, mold, or water stains on your basement walls, it’s likely due to hydrostatic pressure. Left untreated, this pressure can create bigger cracks and even result in a flooded basement floor! It’s critical to reduce that pressure before it causes further damage. 

Using a hydrostatic pressure relief system, such as a French drain Pittsburgh, will sump pump removes standing groundwater and reduce the pressure on your foundation. Once that pressure is relieved, your home is protected from mold, leaks, and even future flooding. 

Fun Fact: The French drain Pittsburgh is actually an invention from right here in the United States! They are named after inventor Henry Flagg French, who wrote about them in his book Farm Drainage in 1859!

Interior VS Exterior French Drains

When choosing a French drain Pittsburgh, you’ll need to decide on an interior or exterior option. While exterior drains are generally more effective, there are a couple of considerations. Installing an exterior French drain will require excavating the soil around the perimeter of your home or business. We’ll need to be able to work around (or temporarily remove) any porch, deck, or other structures around the perimeter.

Installation is easiest in the spring or summer when the ground isn’t frozen. Exterior French drains will need to be dug and installed around other sub-soil objects like gas and water lines. Finally, because exterior French drains are installed underground, they can be harder to maintain. Maintenance is often needed if debris, roots, or gravel unintentionally fall into the drain, or if the drain is crushed. Exterior drains may be an ideal option for new construction, as the perimeter excavation can be done before constructing a porch or laying other lines.

An interior French drain Pittsburgh has a few advantages. An interior French drain is installed by using a jackhammer to drill into your basement’s concrete floor. This means that installation is more straightforward. There’s no need to remove a porch or water line, but you will need to remove all of your personal belongings for our crew. An interior French drain Pittsburgh can be installed in any season because no excavation is needed. In addition, interior french drains are unlikely to be clogged with dirt or debris because it’s filtering water that has already seeped through concrete. Finally, any maintenance needed is easier. We won’t need to excavate the drain in order to repair it.
