French Drains in Dallas
What are French Drains?
French drains are trenches that contain a perforated drain pipe which is surrounded by gravel. Either the entire trench is lined with filter fabric, or the pipe is wrapped in filter fabric. Generally, the trench is covered with grass.
When does Advanced recommend a French Drain installation?
French drains are designed to remove water that is accumulating below the surface. French drains in Dallas are very good at collecting water that is accumulating in marshy or boggy areas that have been created by over watering or poor drainage.
How long do French Drains last?
If the trench for a French drain is lined with filter cloth, the drain will last for many years. If only the pipe is wrapped in filter cloth, soil will wash into the gravel in just a few years.
How does Advanced install them?
How to: French Drain Installation
Advanced starts with digging a trench and grades it so the bottom is flat and evenly sloped. Next, we line the trench with filter fabric. After the fabric is placed, 1 to 2 inches of gravel is placed in the bottom of the trench. A perforated pipe is then laid on the gravel. The trench filled to a level 4 to 6 inches below the surface and the edges of the filter fabric are laid over the top of the gravel. Finally, the top of the trench is filled with soil.
Advanced’s French drains in Dallas can either work with gravity, if enough of a slope is available, or be connected to sump pumps depending on your need. We never connect them to downspouts since the purpose of a French drain is to get rid of subsurface water. If you fill up a French drain with water by overloading it, you can cause serious damage to your home.
