water dropFrench Drains

We Are the French Drain Installation Experts...

french drainFrench drains are used to direct runoff away from buildings and to drain standing water into an area where it can't do any harm. A french drain is a trench covered with gravel rock that redirects surface and ground water away from an area. A french drain can have perforated hollow pipes installed below the inside bottom of the foundation floor to quickly remove water that rises from ground water that rasies the water table.

French drains are common drainage systems, primarily used to prevent ground and surface water from penetrating or damaging building foundations. Alternatively, the french drain technique may be used under certain circumstances to move water, from around the exterior of a building or to distribute the effluence from a outgoing sewer line to a septic drain field at the outlet of a typical septic tank sewage treatment system. French drains are also used behind retaining walls to relieve ground water pressure.

 

water dropHow We install the French Drains.

drain systemTo install this kind of drain, work is performed from the inside of the basement. The perimeter of the basement floor is jackhammered down to the footing and the cement is removed. A trench is formed by removing the dirt around the perimeter approximately one foot away from the foundation and 18" to 24" below the floor level and pitched. Then we lay down a layer of micro-fiber to filter sand from the water entering the pipe. A layer of stone is then laid in the trench, and a perforated drain pipe is laid on top of it. Then we cover the pipe with more stone and on top of the stone we fill the opening of the trench with a layer cement all around the perimeter closing in the trench. Then a hole is made in the floor to receive a sump basket which is attached to the french drain system and a pump is installed and connected to an electrical outlet. This unit is cemented into the floor and is closed in with a plastic basket cover which allows for the pipes which will evacuate the excess water. Through the french drain system ground water is collected from the subsurface area below the floor as the water table rises. This drainage system relieves the hydrostatic pressure (water pressure) on the underside of the basement floor keeping the water table below the floor level, and through the use of a sump pump the excess water is pumped away from the building and foundation thereby keeping the basement dry and clean for years to come. Before we are done we clean up all the debris so you are left with a nice, neat job.

Good drainage is important to ensure that a home stays dry and free of mold. If groundwater collects in the basement, it is not only an inconvenient eyesore for the homeowner, it can also lead to wood rot and mold creating health problems for those most sensitive to mold. The most reliable way to eliminate undesirable, free-standing water is to install French drains with perforated pipes, filter fabric and gravel.
There can be health risks for people who are sensitive to mold. These health issues occur when people inhale airborne mold spores. For some people, a small quantity of mold spores is enough to cause health risks, while for others, a larger amount of mold spores will begin to affect overall health. Children, pregnant women, seniors, and individuals with respiratory conditions are at higher risks from inhaling mold spores. Some of the problems that can occur as a result of mold exposure include, but are not limited to:

  • Aches and pains
  • Nasal and sinus congestion
  • Dry, hacking cough
  • Central Nervous system problems
  • Respiratory problems (wheezing, asthma attacks, etc)
  • Irritation to the eyes, skin, sinuses, and throat

There are more serious health issues which seem to be associated by a toxic condition created by mold. It is usually a black, mold but can also present itself as greenish looking. Black mold thrives in areas that have consistent source of moisture. Constant exposure to black mold may lead to more serious health problems. Therefore this kind of mold should be removed as soon as possible to avoid any further exposure and possible health problems.

 

 

water dropSurface Water entering through the walls

Be careful o f those companies that suggest applying a coating of some water barrier or offer to apply a paint product on the walls of the foundation in order to keep water from entering the building. Very often removal of the water source can eliminate any further problem with water getting into the property. Before you commit to doing anything gutter overflowit is important to find out how the source of surface water is entering the basement.

At Dennis Diffley & Sons Inc. the first thing we do is analyze the source of your water problems. That means we find out how the water is getting into the property. We evaluate you how your roof drain system works and where rain water flows during a rainstorm. A gutter or downspout that is plugged up with debris may be sending rainwater over the gutter, down along the foundation, and into the house. Regular cleaning of the gutter and downsputs can stop rainwater from entering the basement area, or installing a gutter guard that prevents debris from getting into the gutter system will effectively end this kind of problem. No amount of water barrier applied to the walls is going to work effectively if you continually pour water down along your foundation. So save your Money!

If the gutter system is not blocked, but rainwater is still overflowing, the downspouts may be clogged. Sometimes the gutter system may be incorrectly sized for the surface area of the roof it has to handle, or simply insufficient for the amount of the house run off. If this is the problem getting larger gutters, adding another downspout, or increasing the downspout size and its corresponding gutter opening may resolve the problem.
Downspouts should extend at least 10 feet away from the foundation to get the water away from the house. Improperly placed downspouts can direct rain water alongside the house and cause seepage into the ground close to the foundation resulting in pooling at the foundation.

down spoutCheck the landscaping terrain of your propery to see if it has sloping toward your property set or has settled in certain areas allowing pooling near the house sending water toward the foundation. Check the paved areas, walkways and driveways, for water being directed toward the home or building. Proper slope has to be regained and may mean replacing pavement.
