Multi-Flow drainage systems are ideal for drainage in residential
settings. It is used beneficially in yards and gardens, along driveways
and sidewalks, near foundations and retaining walls and under basements.
explosion of Multi-Flow usage is part of a larger trend toward more
extensive and intensive usage of yards and gardens. Homeowners increasingly
want to keep grass, shrubs, trees, and flowers on their entire property
healthy, attractive and ready for use. Heavy use or yard work during
saturated conditions compacts the soil and consequently threatens
the plant life. Multi-Flow is also often used to keep water from flowing
under or even into houses, basements, and outbuildings.
drainage is all too often ignored during the development of new housing
additions. Once the landscaping is in place with established turf,
Multi-Flow becomes an even more attractive solution to drainage problems
due to its unobtrusive installation method.
or horizontal installation?
Most commonly, Multi-Flow is installed vertically. If a trench
is needed, vertical is the orientation of choice. Multi-Flow
can be installed horizontally where construction requires the
top soil to be stripped away. It is usually stripped away to
a somewhat impermeable clay base and new fill is then hauled
in. In these cases, Multi-Flow is rolled out horizontally before
the new fill is hauled in. The time and cost of trenching can
be by-passed. In planters and under pavers are two common examples
of horizontal installations.
of using Multi-Flow in your residential drainage
Whether it is new construction or addressing an existing problem,
Multi-Flow is a wise choice because Multi-Flow is:
easy to use
3) long lasting
Easy to use Multi-Flow is a product that homeowners,
contractors, and landscape architects love to work with because
of its shape, the adaptability of the overall system, and the
flexibility of the pipe.
Because of its panel shape, Multi-Flow can be inserted
vertically. This means that a trench can be dug with a small
walk-behind trencher or in some cases by hand. The result
is less excavated material to haul away, less backfill to
haul in, less time spent, less damage to the landscaping,
and of course, less expense.
Not only are Multi-Flow connectors easy to use, there
are a lot of them. Any configuration that is appropriate
for a given site can be carried out using one or more of
the 60 Multi-Flow connectors.
Multi-Flow is easily bent making it convenient to work
with, suitable for making tight turns, and easily joined
Drainage systems must be able to collect water and transport water.
Multi-Flow excels in both regards:
water Water can enter a Multi-Flow drain more
quickly because Multi-Flow has greater surface area than
traditional round pipe. The more drainage product that there
is in contact with surrounding saturated soil, the more
quickly drainage can take place.
water Once water has entered Multi-Flow flow
channels, it moves away from the saturated area quickly
because the channels are round and unobstructed, unlike
those in other panel shaped drains.
lasting Multi-Flow enjoys longevity because of:
Multi-Flow is designed to withstand heavy loads. Able to
withstand loads well in excess of 6,000 psf, Multi-Flow is
not going to collapse due to heavy surface loads in shallow
installations or due to earth weight in deep installations.
filtration methods The Multi-Flow system includes
a heavy effective geotextile filter. This high quality fabric
acts as an excellent secondary filter, keeping Multi-Flows
flow channels clean and open. Clean coarse sand acts as
a very effective primary filter. Due to its shape, Multi-Flow
is easily encased in sand, assuring a long life. When placed
in a 4 inch wide trench Multi-Flow is readily protected
in this way. This would be difficult if not impossible using
French drain methodology.
A completed Multi-Flow system typically costs about half as much
as a comparable French drain system. The longer life of the Multi-Flow
system brings the per year cost down much further!
