There is a better solution!!!!It’s called an exterior French or Foundation Drain, and this will keep the water out of your basement before it ever has a chance to get inside. This method is far superior because the water and dampness stay outside, and it needs no electric!!! Installation: Installing a French drain is usually a simple, but labor intensive project. Obstacles, however, can make the project costly and time consuming. These include: Decks, concrete walkways, driveways, tree roots, boulders, and underground utilities. If you build a house, be sure to ask the builder to include inside and especially outside French drains on your new house. They may not seem important now, but as your house ages, water incursions can change over time, and a cheap installation now may relieve expensive headaches later. During construction, the cost of a French drain is negligible. Spring for it. Demand it! |

(French drains). For residential or other small-scale buildings, perforated 4 in. (100 mm) plastic, ceramic, or concrete pipe is normally used around the periphery (see figure 9). It is laid in a trench, at the level of the footings, and protected from sediment with wide roll protective filter fabric. The drains will collect rain water falling within the catchment area or lower the ground water level, thus reducing the quantity of water affecting the wall. The collected water must then either drain by gravity (preferred) or be pumped to nearby storm sewers. When properly installed and sized, footing drains perform well. They will positively drain water from the catchment area. Drains can last indefinitely, but periodic inspection and clean-outs are required to ensure that silt does not build up and that tree roots or animals have not damaged the piping. |
Footing drains are most practical for suburban sites or others where the entire periphery of the building is readily accessible and positive drainage is possible (i.e., pumping is not required). Urban site can pose several complications including the inaccessibility of the building periphery to trenching and inability to establish positive drainage of collected water (pumps are often required). |
Our Bobcat compact track Excavators have the distinct advantage over a traditional backhoe because they can articulate their booms thereby allowing them to excavate immediately adjacent to a building’s foundation. This is critical in exterior foundation drain installations which are frequently used to waterproof a basement with a gravity type system. One of the many advantages to installing an exterior foundation drain to remove water via gravity is that it takes away the lifeblood of mold and mildew. Our French Drain systems designed with Paraseal's combined rubber and Bentonite membrane will not only remove the water seeping into your foundation, but also remove the source for mold that is growing in your damp walls. Studies have shown that mold spores can be harmful to the health of a home's occupants, and also that by eliminating the source of water completely can also kill the mold. Many businesses attempt to cure a home's flooding basement with an "indoor" style French Drain. This type of system lacks several key benefits of an exterior gravity system. First and foremost, an interior type system encourages the water to flow through your foundation walls which by definition keeps the walls wet and hospitable to mold spores. An exterior foundation drain properly designed will keep your home's foundation walls dry and safe from the weakening structural effects of constant dampness. Second, an "interior" French Drain doesn't actually get rid of the water. Instead it directs the water into a small swimming pool in your basement. Not only does this pose a potential safety hazard for small children, but also it forces you to rely on electricity and a mechanical pump to keep your basement dry during a heavy storm. Everyone has experienced a power failure during a storm, and it's most likely that a pump will fail when you need it the most. These are among the reasons why an exterior gravity based foundation drain is a much more efficient and reliable method for drying up your basement. Thirdly, an exterior drainage system has the added benefit of also drying up your lawn and landscape so that pets and children have a cleaner environment in which to play in. No "interior" type drainage system can accomplish all of that and operate with no moving parts, electricity or maintenance!!! |

This house in The first step is to excavate below the basement floor to the foundation. Next, the concrete wall is carefully cleaned and then waterproofed with a tar based substance. Filter fabric is then installed to protect the trench. A perforated PVC pipe is used as a conduit for the water to flow through, and then the entire trench is backfilled with plenty of 2 1/2” stone. The entire run of perforated pipe is continuously sloping downhill to remove the unwanted water twenty four hours a day, seven days per week. This entire system works by gravity – NO PUMPS or ELECTRICITY to burn out or go out!!! |

| Perforated piping is then fitted where it will ultimately be protected by filter fabric and surrounded on top and bottom by 2 ½” stone to act as a conduit for any water to flow through on its way to the sloping PVC pipe. The pipe will always slope away from the residence as it carries away the unwanted water. The end result is a basement that is dry by way of a gravity system that removes water twenty four-seven without allowing it to penetrate your basement walls or requiring the use of an electric sump pump to remove the water. | ![]() |
| A deep trench is dug from the end of the house towards the city storm drain. Notice the amount of water draining away from the house through this deep trench. Again, filter fabric, perforated PVC pipe, and 2 ½” stone are used to carry the unwanted water away from the home. Ultimately, the drain is completed with the end result being a bone dry basement by way of an outdoor French Drain. This basement is now ready for a children’s playroom which includes carpeting without worry of future flooding!!! Among the advantages of an outdoor drain are that no water seeps through your home’s foundation walls, thereby eliminating water damage to your foundation. Additionally, an outdoor system does not rely on a sump pump to remove water collected in your basement. Water is routed away from your house before it even gets to the basement. When considering an indoor type French Drain, ask yourself if you would rather rely on a sump pump and electric during a storm, or if you would prefer good old gravity to remove the water instead. Pumps and electric can fail, but gravity is always there. Additionally, this type of French drain has the added benefit of removing all roof water through the leader system and also in quickly drying out the rest of the property and landscaping so that the children and pets can play outside without getting muddy!!! No indoor only drains can accomplish that, too. Dollar for dollar, an exterior French Drain provides a much better value because it not only removes water from your basement, but also from your lawn areas!!! | ![]() |
Ultimately, the drain is completed, the property is graded, and a Paving stone patio is installed in the rear yard. A tremendous value has been added to this house by making the wet basement now useable for a play room and also in drying out the rear soggy yard! The hassle of burning out sump pumps, occasional flooding, and constant dampness are all gone thanks to a GRAVITY based foundation drain at this home. |

| Our 337 Excavator easily lifts this concrete seepage pit to place it at a precise elevation to disburse water collected onsite. This tank is designed to allow water to flow out all sides and also the open bottom. Several feet of stone are placed below and around the tank as well as in a rectangular area over six hundred cubic feet. This design allows for storm water run off remaining onsite without causing flooding problems to either the property owner or his neighbors. This is accomplished with a large area of excavated earth filled with loose stone and into which water is directed for infiltration into the ground. Many towns today will require storm water to remain onsite when building a new addition to an existing home. It is an environmentally friendly manner to dispose of your storm and drain water without adversely affecting one's neighbors. |

This home in New Jersey had a saturated backyard even during the summer months. Mosquitoes were a major problem due to this persistently saturated condition. Following numerous quotes from area landscapers who simply wanted to add top soil, the homeowner called upon Bobcats for Hire to solve the water problems plaguing their property. A comprehensive design was proposed that included a combination of French drain and also connection of leader drains. |

| Upon excavation, we found a large contributing factor to the problem which could only be solved using our gravity based system of drainage. The neighbor’s sump pump and roof drainage water were being surreptitiously directed to the border of the properties with nowhere to go except in the lawn. (See pictures 1 and 2 above)A long trench had been excavated approximately four feet deep and diagonally across the property so that the water could be routed to a city storm sewer instead of this customer’s backyard. The drain is also protected with Typar filter fabric and backfilled with 2 ½” crushed stone. Two pipes are used as conduit for the water. The lower pipe at the bottom of the trench is a four inch perforated PVC pipe used to carry the seeping water to the storm basin. The visible pipe is also PVC, but solid to carry away the water intruding from the neighboring property directly to the storm sewer. The entire trench is then wrapped in the protective fabric where lawn will be replanted. The end result is a dry back yard with the added benefit that the basement sump pump now runs much less frequently than it did prior to the installation of the drainage system in the backyard. This entire system runs by gravity and never needs a pump or electricity! Professional grade filter fabric is being used above to protect the trenches from sediment buildup. This fabric is shipped on a fifteen foot wide roll to ensure that the new drain is properly protected. The fabric allows water to flow through to the drain, but keeps all sediment from contaminating the stone. Filter fabric is the best way to ensure that your drain will perform for many years to come. |

| Be smart and do the job right the first time. We have installed many exterior gravity systems to homes that already had and "interior" style drain that just didn't do the job properly. Add substantial value to your home by installing an exterior French Drain system to dry up your basement, lawn, and landscape!!! |
