French Drains Columbia, MO
The purpose of a French drain is to collect surface water at a low point and carry the runoff water away to a lower elevation via gravity and a pvc/gravel drain system to a designated area lower in elevation.
Once determined that there is adequate fall in elevation on your property we can determine where the excess water runoff will flow to. Many times it is necessary to route downspouts in conjunction with a drainage system to fit our overall drainage plan for your property.
The process of installing a French drain- First we create a trench which falls in elevation beginning at the low point where water collects and gradually falls to the point where the runoff water will exit. The trench is then lined with a commercial grade filter cloth to prevent sediment infiltration. A 4” solid slotted pvc pipe (not the vulnerable corrugated pipe) is then placed in the trench and covered with 1” clean drainage aggregate. The filter cloth is then folded over which encases the drain system and topsoil is then placed over the French drain, restoring the appearance and functionality of your lawn.
Our French drain systems are guaranteed for as long as you own your home. Once installed correctly they require no maintenance other than ensuring the drain grate and exit remain unobstructed and clear of debris.
Downspouts- Is is of critical importance to carry roof water runoff away from your homes foundation. If not, downspouts pointed at your foundation/footings will eventually compromise the structural integrity of the foundation and lead to additional settling or damage. The black corrugated pipe often used by others WILL collapse, fail and clog with debris. We use only solid 4” pvc in our downspout installations. We determine the correct area do divert the roof runoff to and ensure the appropriate fall before beginning the project.
