Drainage Correction Systems

Given the nature of North Texas clay soil, proper drainage is essential to foundation health and landscaping longevity. Pooling water can lead to many issues, including foundation instability and soil erosion. FCS Foundation Repair offers various solutions that meet your budget and resolve water issues


 

French Drainage System

French drains use channels that direct ground and surface water away from your property. Water moves freely through a graveled trench that contains a perforated drain pipe. Either the entire trench or drain pipe can be lined with filter fabric.

If trenches are lined with filter cloth, the drainage system will last many years. If the drainpipe is not lined, the soil will wash into the gravel and the system will need repair in just a few years.

Frequently Asked Questions

WHAT IS A FRENCH DRAIN?

French drains are trenches that contain a perforated drain pipe enveloped in 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 FCS RECOMMEND USING A FRENCH DRAIN?

French drains are designed to remove water that accumulates below the surface. French drains are very good at collecting water 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 FCS INSTALLED THEM?

We start with digging a trench and grade it so the bottom is flat and evenly sloped. Next, we line the trench with filter fabric. After the fabric is installed, 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 is then filled 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. The French drains can either work with gravity, if enough of a slope is available, or connected to sump pumps depending on your need.

Channel Drainage System

A channel drainage system is a good option for surface water that pools along with foundations, patios, pools, and other such areas. The system requires a superficial channel (or trench) that is capped with a surface grate. Because a channel drainage system acts as both a collection pipe and water carrier, it’s affordable and generally easy to install and maintain.

Drainage Swale with French Drain System

A drainage swale is essentially a broad, shallow trench that is usually covered or lined with grass or other vegetation. It controls flooding, pooling, and erosion, but is less obvious than a channel drainage system. By incorporating a French drain system with a drainage swale, water is invisibly directed away from your property’s foundation.

Surface Drain with Collection Boxes

Surface drains collect rain and sprinkler runoff and direct water away from low areas. Collection boxes, also known as catch basins, are placed in the ground slightly below ground level and covered with a grate. A pipe is connected to the collection boxes and directs water away from the area.

Dry Well

A dry well is an underground system that captures excessive water and allows that water to slowly soak into the ground (known as percolate) and dissipate into groundwater. The system contains a collection box that captures overflowing water and a perforated pipe that transports the excessive water to a porous container. The container is buried completely in the ground in a pit filled with gravel.
