Who Installs French Drains Near Me? Discover Below.
French Drains consist of a subsurface trench filled with clean rock (and more often than not, a perforated pipe) which captures and redirects / relocates water surface water and subsurface groundwater from one area to another. French drains with a perforated pipe allows water to quickly accumulate in the pipe and the pipe then transports the water efficiently to the designed location of the piping system.
French Drains in the St. Louis Missouri area are primarily used to prevent groundwater and surface water from pooling, infiltrating and ultimately damaging foundations, lawn areas, landscaping areas, pool areas, athletic fields, streets & highways, airport runways, and many more areas. Interior french drains are also common and are typically connected to a sump pump installed beneath the basement floor – visit our Basement Waterproofing for more details.
Property owners and engineers alike commonly use various names to reference a French drain configuration… these include “french trench drain”, “filter drain”, “blind drain”, “rubble drain”, “rock drain”, “gravel drain”, “drain tile”, “perimeter drain”, “french ditch”, “ditch drain”, “subsurface drain”, “subsoil drain”, and “agricultural field drain”.
Reasons Our French Drains Are Needed
How Our French Drains Solve Your Water Issues
Drainage Team French Drain Installation
French Drain Excavation
Our French drain excavation is a detailed task that is done using specialized equipment, hand tools and a transit to shoot the grade during the entire excavation. We crumb out the bottom of the trench while we dig the trenches to ensure that they will be the most effective at capturing and discharging water. During the excavation process, we use whatever tools necessary to get the excavation done. All public utility lines are marked prior to the excavation process starting.
French Drain Fabric
Next, once the excavation is completed and at the proper levels, we start installing filter drainage fabric inside the trenches. Filter fabric is used to keep soil sediment from seeping into the French drain space and getting into the French drain gravel and perforated pipe(s).
Our filter fabric is custom spec’d on a project-by-project basis and is sourced from our specialized vendor network. We want the strongest fabric that keeps debris and sediment out, but allows water infiltration extremely quickly.
French Drain Piping
Once the fabric is installed and secured, we install the discharge piping (water accumulation piping) through the inside of the French drain. We typically use schedule 35 perforated piping inside of our French drains. As we install, we utilize PVC connectors to ensure the piping is precisely contoured to the shape of the French drain.
At the end of the perforated pipes, we will connect the piping into solid schedule 35 pipe(s) which will transport the water from the French drain area to the location where we would like to discharge this water.
French Drain Rock
The next step in our process is to install the rock / gravel in the French drain trench that will act as the filter to the water flowing into the system. We use specialized filtration rock which is determined by the application and site type.
Our rock is sourced through our specialized vendor network which ensures that we use the best type of rock for the French drain application.
Exposed French Drains
Exposed French drains are extremely effective at capturing and removing surface water while also capturing subsurface water buildup in the area. The top of an exposed French drain allows water to free flow into the top of the systems while also creating a path of no-resistance for subsurface water to be drawn to underground.
Exposed French drains can also be referred to as trench drains as they are basically a trench that allows large amounts of water to free-flow into the top and be relocated to the desired area (that site elevations allow for without using mechanical, external pumps – hopefully).
Decorative French Drains
Sod Top French Drains
The most traditional French drain is a non-exposed, covered French drain. These types of French drains are most commonly covered with sod once completed. Non-exposed french drains are most common in lawn areas, athletic fields, etc. They allow sitting water in the lawn to make its way into the French drain system along with capturing subsurface water buildup from the surrounding soil areas.
When our crews are installing these types of systems, we install filter fabric on the top of the French drain rock along with our proprietary special blend of soil to allow sod to grow while it simultaneously allows water to flow into the French drain efficiently. Once several inches of our special soil is installed on top, we then install freshly cut sod from our premium local sod farm partner. Sod is freshly cut and delivered to our jobsite all in the same day.
