Why do retaining walls fail?
Lack of proper drainage is the most common cause of retaining wall
failure. Drainage and soil filtration are vital to designing walls and maximizing
their service life. Retaining wall drainage systems serve two functions. First,
they drain the water (hydrostatic) pressure from behind the wall and, second,
they stop soil from eroding through the drains (soil filtration). When drainage
systems clog and fail, excessive water (hydrostatic) pressures builds up on the
retaining wall. Eventually, the retaining wall will show signs of destress.
Sustainable Weep Hole Filters are the perfect solution.
Water always Wins:
The solution.
Earth Retaining Structures (ERS) are failing daily due to clogged or insufficient drainage
systems. JET Filter System will help protect your investment and avoid costly repairs.
Water always seeks the easiest path to flow. Therefore, drainage systems must
always be the “easiest path”. Traditional retaining wall drainage systems are
installed behind the wall, buried under the soil. Over time, drainage
performance decreases as soil particles begin to clog the filter fabric. Once
clogged, the drainage system stops being the “easiest path”. At this point, water
will find another path or backup behind the wall. Fixing failed drainage systems
buried behind the wall require costly excavation.
What are Sustainable Weep Hole Filters?
Sustainable Weep Hole Filters by JET Filter System provide drainage and soil
filtration. Installed through the front of any new or existing retaining wall,
Sustainable Weep Hole Filters help prevent failure as they reduce water pressure
and prevent soil loss. Most importantly, Sustainable Weep Hole Filters are
always easily maintained, they can extend the life of your valuable investment.
Weep Hole Filters can be installed on seawalls, bulkheads, bridge abutments,
wing walls, stormwater channels, box culverts, dam spillways and even
underground parking garages. They are the perfect solution for concrete walls,
all types of sheet pile (steel, vinyl, aluminum, composite, etc), MSE walls and
even wooden bulkheads.

The outlet drains are
provided with check valves
to prevent the backflow of
water from the channels into
the drainage system.
Check valve drainage should
be used for channels where
continuous relief of
hydrostatic pressure is
important to channel
performance and to help
ensure no soil loss or panel
failure.
With storm tidal or wake
action concerns, the weep
hole system will facilitate the
passing of hydrostatic water
pressures (ground water) and
stop soil loss from behind the
seawall structure.
The backflow preventer
check valve will stop the
passage of water from
entering through the
structure from the seaward
side.
Water control is a major
factor with regards to safety
and integrity of the
structure.
Seepage must be controlled,
It can progressively erode
soil from the embankment or
its foundation, resulting in
rapid failure of the structure.
The drainage system is
designed to prevent
migration of soil particles but
still allow the seepage to
drain freely.

“As climate changes and sea levels rise, it pushes groundwater up behind sea walls for more and
more days per year, thereby increasing hydrostatic pressures that can impact sea walls.”

The conical design of our 4″ dia. maintainable weep hole
filter gives 210% more filter fabric surface area than a 4″ dia.
traditional weep hole. The increased surface area allows our
filters to produce greater than 200%* additional water flow.
The 4″ dia. weep hole filter also has 9 times the surface area
of our 2.5″ dia. ABS filters and 1.5 times the surface area of
the 3″ dia. units. As a result, the 4″ dia. units are the most
versatile filter and can be used in almost any application.
Storms, sprinklers, waves, groundwater and other events can
deposit large amounts of water behind a wall. It is important
to drain the water before it causes damage. Our 4″ dia. weep
hole filter can drain 20.79 gpm*.
