Because of the damage that water can do, waterproofing your house is integral to its safety. Making your waterproofing contractors in Los Angeles is a multifaceted process, involving various building materials in the construction of the home itself, plus additional items such as sump pumps and french drains. Also called a perimeter drain, land drain, rock drain, rubble drain, blind drain, or french ditch, a french drain is used to collect water and carry it away from any structure on your property, including a house, garage, guest house, or other building.

What is a french drain?

Essentially, a french drain consists of a trench filled with gravel. In the middle of the gravel and running along the trench is a pipe with holes in it. You seldom notice french drains, because the trench is generally filled on top with soil, often grass or shrubs, sidewalks, porches, etc., sit on top of the trench. Thus, while french drains are extremely common, they are rarely obvious. On the plus side, this means that they will not mar the look of your house and yard. However, at CXC Contracting we recognize how important it is that a french drain be properly constructed, with provisions for cleaning out and maintenance in the future. Otherwise, it will have to be dug up at some time, with all the associated mess and inconvenience.

How do french drains work?

Water on the surface filters down through the system, and Is carried off by the pipe. If the french drain is on a slope, and can drain downhill, it works without any extra help. In a case where such downhill drainage is not available, the french drain is connected to a sump pump, which forces the collected water away from the structure. Although based on a very simple principle, french drains are actually quite effective. For that reason, they are one of the most common methods used for keeping water away from the foundation of both residential and commercial structures.

Where are french drains placed?

French drains are placed either on the outside of a structure, or on the inside. In California, the inside version is less common, since these generally go inside basements, which few houses have. French drains can also be used to draw water away from retaining walls, which can be vital, considering the important role such walls play in maintaining the security of your property.
