Hydraulic and Erosion Control - Channel
Linings
A channel lining application is one in which an erosion control
system is used to completely line a channel from one bank
to the other. Where the river banks alone are protected, this
is known as ‘bank protection’.
Maccaferri offers a range of erosion control solutions to
suit most flow conditions, and design life requirements;
- Reno mattress - For very high shear resistance,
long term applications
- Rock confined in the Reno mattress cage offers
twice the shear resistance of rip-rap of the same
rock dimension. (Shield’s coefficient=0.14
for mattresses and 0.047 for Rip rap)
|
|
- Gabion mats - For very high shear resistance,
long term applications
- These are long (up to 100 ft) gabions for use
on demanding high shear stress projects where
economies of scale can be realized. They are filled
with rock and offer similar benefits as Reno Mattresses
|
|
- MacMat® and MacMat R® - For high shear
resistance, long term applications
- These High Performance TRMs (turf reinforcement
mat) consist of a 3D polymeric fibrous matrix
which in MacMat R, is additionally reinforced
with our woven steel wire mesh. They are fixed
to the slope to be protected, and facilitate vegetation
establishment
|
|
- Biomac® - For good shear resistance, short
term applications
- These RECPs (rolled erosion control products)
consist of a coir and/or straw blanket, confined
within lightweight polymer nets. They are fixed
to the slope to be protected, and facilitate vegetation
establishment. They can last up to 3 to 5 years.

These channel lining solutions can be designed using Maccaferri
Macra 1™ 2002 design software, available in the download
area.
Due to their modular construction, gabions and Reno mattresses
are ideal for many types of channel works, including weirs,
culverts, bridge abutment protection and pier protection.
More information on this can be found in the Bank
Protection and Culverts, Weirs and
Groynes webpages.
