ARMORED EROSION CONTROL
Embankment Protection
Slope and embankment erosion, particularly along
coastal shorelines and inland waterways, poses a
serious environmental problem. The stability and
performance of many civil engineering structures
have been impaired or destroyed by unchecked
erosion. '
Armored protection systems are often used to guard
against erosion caused by waves, tides, currents,
surface run-off, and ground water seepage. Integral
parts of an armored erosion protection system are
energy dissipation and filtration materials.
./
Graded-aggregate systems (usually multilayered)
have been traditionally used with limited success
beneath armor both as energy dissipators and filters
to prevent the washout of soil fines.
Such aggregate filters are difficult to source, install,
and inspect, and even when installed properly, they
are susceptible to erosive forces.
Mirafi 700X erosion control fabric provides an
effective, cost-efficient alternative to graded
aggregate systems.
Among its performance features are:
· Acts as an energy dissipator by shielding the
slope from the erosive forces of moving
water;
· Allows adequate ground water to pass from
the protected slopes while retaining
underlying soil particles;
· Withstands armorment installation stresses
because of its exceptional strength;
· Provides excellent clogging resistance and
filtration properties:
· Does not wash out from beneath the armor,
thus providing a reliable filtration and energy
dissipation system.
In addition to its outstanding performance
advantages, Mirafi 700X has a significantly lower
installed cost than multilayered or even
single-layered aggregate systems.
