SLOPE PROTECTION
Production: MacMat R 6822 GO
EROSION CONTROL ON THE AMUR GPP RAILWAY AMUR REGION, DISTRICT OF THE CITY OF SVOBODNIY
Construction site Amur GPP
Problem description
The railway was built from the station of Ust-Pera of the Trans
-Siberian Railway to Amur gas processing plant for equipment
and materials transportation and finished products delivery.
The height of the railway embankment is more than 26 meters
and slope length exceeds 50 m. Such high and extended
slopes required the stabilizing.
Solution description
To stabilize the subgrade slopes, the project envisaged the
slope strengthening with MacMat R 6822 GO, geosynthetic
material, reinforced with a double twist wire mesh. To ensure
the subgrade stability the 640,000 sq. m of reinforced geomat
were installed. The steel wire mesh of the geomat has
additional PVC coating that protects the wire from the
chemical and biological effects of the environment.
The geomat MacMat is a three-dimensional panel of
polypropylene fibers tangled together and forming a highly
elastic layer of high porosity. Thanks to this structure, the
plant roots sprout through it. Tangled with the material fibers
they form complex structure that stabilizes the topsoil.
For germination of plant roots through the geomat, at the
stage of dumping vegetable soil, hydro-seeding was used at
the construction site.

The geomats at the construction site were installed by the
“NIPIGAZ” JSC. The geomat roll limited weight allowed
avoiding the use of special equipment. So the geomats were
installed by teams of 4–5 workers. The standard width of a
rolled material is 2 meters when the roll length is up to 75
running meters. This ensured quick covering of large areas.
Properly organized work process allowed team to install from
3 to 5 thousand sq. meters per shift.
The geomats are made with high-quality primary raw
materials at the LLC “MACCAFERRI GABIONS CIS” plant in
Zaraysk (Moscow Region). The laboratory thoroughly controls
the quality of each geomat batch.
