The designers at Bobcats for Hire will carefully
evaluate your site conditions to design and
install an appropriate drainage systems to your
location that will meet the needs of your site
while complying with local stormwater laws.
Our systems are constructed using rigid PVC
pipe, wide roll protective filter fabric, and plenty of
2 ½" crushed stone for drainage.
We will shoot elevations and calculate both
flow rates and pipe sizing to ensure that your
system will work as intended. Your project designed by our engineer and the installation is also carefullly monitored to ensure that it is installed to our standards. This care in installation ensures that your underground drainage system is going to function as intended for many years into the future. Our equipment
uses wide rubber tracks that operate excellent
in swampy, wet areas which are usually found
in drainage applications. These wide track machines
enable our company to install a professional
drainage system in much less time, with much
more crushed stone, and also with much less
damage to existing lawns than conventional rubber
tire machines. Because larger French Drain systems
are constructed below ground and may require
as much as fifty
to seventy-five tons of stone, it is imperative
to hire a contractor who understands the nature
and limitations of water flow and is using dedicated
track equipment. This ensures that your project
will be designed correctly and will receive
the required, difficult to move materials to
function as intended. Our articulated excavators
allow for digging in compact areas and also
against a building which is usually needed when
addressing a leaky basement.
Free "As Built" with every installation on request.
We will beat any written estimate for a drainage system that has been designed by an engineer who will also provide an onsite "As Built" that verifies a correct installation.

The purpose of a
French Drainage System is to carry unwanted
free standing water away from a building,
such as your home. French drains are commonly
installed near the perimeter of a building
at the lowest point or anywhere where
standing water is found. The system may
terminate at any point where the water
will not drain back toward the house.
The best approach is to connect to a city
storm drain, where possible, to totally
remove the water from the property. A
second best solution would be to run the
water out to the street or to a dry well.
French drains can
be shallow or deep drainage systems depending
on soil type and grade changes. However,
as with your plumbing waste drainage,
French drains operate on the principle
of gravity. The drain must slope downward.
The minimum recommended slope is 1/4 inch
per foot. If the landscape grade runs
upward along the French drain path you
will have to dig deeper to maintain a
There are many variables that affect how
individual houses develop water problems.
Often it is a combination of factors that
develop over time. French drains work
by curing a symptom, not the cause. They
extract the water collected in the drainage
pipes to an outside location away from
the area intended to be kept dry. It is
always more beneficial to divert water
on the outside of a foundation wall before
it ever has an opportunity to penetrate
the foundation. This method has several
advantages which include reducing or eliminating
mold, protecting the foundation from excess
moisture, and also (usually), the benefit
of a gravity only system.
Despair, we'll repair
Beware of slick salespeople that suggest
an inside French Drain to cure your basement water problems. It
is always more beneficial to divert unwanted water before it
has a chance to penetrate your foundation walls, allowing it to
flow away via gravity instead of using an electric pump
to remove the water from your basement sump pit. "Inside French
Drains" encourage the water to pour through your foundation walls
where it will collect in a sump pit. The only thing between you
and a flooded basement is that small electric pump and a steady
supply of electricity during the storm. Keep in mind that power
outages most frequently occur during a storm. Also, an inside French
drain does not "waterproof" your basement, but instead collects
the water and dampness inside your basement to be pumped out with
an electric pump. Both water and dampness remain inside your basement
with an "inside" French drain.
Basement can be dry and Mold Free,
and so can your's with a properly
designed and installed foundation
The foundation drain and waterproof membrane shown to the right will ensure that this basement will be dry and mold free over time. The exterior membrane prevents the foundation walls from contact with saturated soil, and the foundation drain ensures that water collected has a gravity path to be discharged away from the structure.

Foundation drain and waterproof membrane
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 the NJ region
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!!!
French drains cure ground water saturation
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 to the right) 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.
Some installers do not take into consideration all of the site's unique features and boundaries, and can cause problems for adjacent properties as a result.
Ground water or a well?
This underground well was discovered at a residential property in Nutley, NJ while installing a drainage system at this home. The well was hand dug and built by hand with bricks. Its age was unknown. The homeowner did not know that this 24 foot deep well was buried about six inches below his front walkway entrance to the home. Steps were taken to seal the well to prevent the safety hazard. Occasionally, we will also discover septic tanks that have not been properly filled and can pose a collapse hazard.
is best for your wet Basement
house in New York had been getting water in
the basement, burned out three sump pumps,
and also had numerous wet spots in the backyard
for days following a rainstorm. This
wet soggy condition led to mosquitoes all
through the summer months. Following
a careful assessment of how to best solve
the problem, we decided on installing an outdoor
French Drain along the entire perimeter of
the home in addition to several surface drains
and a French Drain in the backyard.
it costs a little more, but isn't your family's
health worth it?
The first step is to excavate
below the basement floor to the foundation.
Next, the conc rete wall is carefully cleaned
and then damp proofed with either a tar
based substance or waterproofed with a Paraseal
membrane. 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" stoneThe 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 with
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 crushed 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
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
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!!!
Water will drain
by gravity away from this home's foundation.
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.
Another wet, soggy lawn that is now dry
Due to a long, steady sloping rear property, this lot
on the left had been plagued with a continually wet back yard. This
lawn stayed wet even several weeks following a rain. In the
spring of 2003, Bobcats for Hire had been asked to diagnose the problem
and to provide a solution to the drainage issues. Following
our proposal for a solution, this homeowner opted to have his cousin
dig up the yard with a rented excavator. (See photo below) Following
two days of destruction, the homeowner called Bobcats for Hire to
repair the damage and complete the proper installation of the needed
drainage system. To the left is a photo of a trench running
across the length of the property. The black filter fabric
is used to protect the drain, while the perforated PVC pipe and 2 ½" stone
are used as a conduit to carry all unwanted water off the property. The
trench is later backfilled with stone and covered with the filter
fabric for protection. Due in large part to the depth of this
installation, the backyard lawn had become noticeably dry even prior
to the completion of the work!!! The children can now play
safely in the backyard without later bringing mud intothe home.
NOT to dig for a French Drain
ever use your cousin "Vinny")
This fellow learned the hard way that it's best
to leave the design and installation of a French Drain to the experts
who do it every day.
This house in Hackettstown, NJ
was the lowest property of all the adjoining lots. Water flowed onto this lot from all directions, and during
even moderate rainstorms, the backyard became an unwanted swimming
pool. This backyard never dried out, even in the summer months. In
this case also, the homeowner started the project only to find that
it was much too large for a do it yourself type project. Our
expert design routed all of the water by gravity to a large collection
basin where it was then pumped out to an existing city storm sewer
across the street. This design worked flawlessly with the result
being a very dry lawn in this same area! (rollover picture

Persistent Flooding and wet lawn year 'round
with mouse for `After') |
This flooded property suffered from a constant stream
of water draining from the neighbor up the hill. Water accumulated
in this area all year long not only due to the long uphill grade
in the background, but also because the neighbor's sump pumps discharged
water almost continuously. Bobcats for Hire successfully designed
and installed a French Drain system to remove the unwanted standing
water from our customer's property. Our rubber track equipment
easily moves about the muck where a wheel type loader would get stuck.
(Rollover Image with mouse for `After') |
A combination of an underground an French Drain system
and surface drains were used to dispose of the unwanted water at this
home.The neighbors property still delivers a steady stream of unwanted
water, but now that water is carried away just as fast as it appears
leaving our customer's property and driveway dry. The "wet" and "dry" pictures
of this job were taken three weeks apart.
Footing Drains will dry your basement
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 Amoco branded filter
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
(preferred) or be pumped to nearby storm sewers.
Footing drains (French drains). Perforated pipe is placed opposite the footing to drain
both ground water and excess water from periodic rain storms.
Such drains will reduce but not necessarily eliminate rising
damp in a wall.
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.
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).
Concrete Seepage tanks will disburse water onsite at an
elevation lower than your basement floor.
Seepage pits are required by many townships
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
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
