Fibertex
South Africa – local distributors for the German-manufactured Naue
Geosynthetics range of geogrids – supplies durable PET (polyester) and
PP (polypropylene)
high-strength
reinforcement geogrids for all civil engineering applications, including
infrastructure projects.
“Fibertex
South Africa partners with municipalities and building contractors, assisting
with the technical support, supply, installation and quality checks of geogrids
used in various infrastructure developments, including the erection of retaining
walls,” says Meera Govender, Technical Sales Engineer,
Fibertex South Africa. “Construction of retaining walls often requires
extensive earthworks, in order to execute the exact design heights and levels
required of a particular structure.
“Secugrid® – a high-performance, soil reinforcement
product produced with state-of-the-art manufacturing technology – strengthens
naturally unstable soil and subgrades to be able to withstand the loading
conditions imposed by modern engineering demands. Secugrid is available in both biaxial form, for use in basal
reinforcement applications and uniaxial form, for use in other markets. These
applications include mechanically stabilised earth walls, including veneer
stabilisation, the segmental retaining wall market, embankment reinforcement
and pile cap platforms.”
Secugrid is
available from Fibertex in biaxial grades of up to 80 kN/m (ultimate tensile
strength) and in uniaxial grades of up to 400 kN/m, or 1200 kN/m with Secugrid
HS ®. However, realistic design conditions demand a strength transfer in the
range of less than 2%, which is the critical factor.
Geogrid
reinforcement decreases the dependency on base course thickness, also extending
service life and reducing long-term maintenance needs.
Secugrid is
manufactured from extruded monolithic PET or PP strands that are drawn to
orientate the polymers into high-tenacity flat bars to achieve a high modulus i.e.
high strength at low elongations. This, combined with the Naue patented welding
technology, provides a structurally sound and stable geogrid. Furthermore, the
surfaces of bars are embossed, offering additional frictional interaction with
the soil. This enables the Secugrid to pick up the load
transfer quickly through both an interlocking and frictional
effect, with little or no movement in the overlying soil materials.
Secugrid is
supplied in rolls and is easy to handle; quick and efficient to install, with
minimal demand on labour resources. The product is also highly resistant to
biological and chemical degradation and installation damage.
Secugrid is a
robust reinforcement material that can be easily and safely installed during
virtually all weather conditions, without the need for heavy equipment or
special construction techniques. Panels are joined and continuity is assured
with simple overlaps depending on the application. Standard cutting tools can
be used for on-site trimming and various geometrical shapes for steep sided
slopes can be formed when necessary.
In addition to the standard Secugrid range, Fibertex South Africa
also supplies Combigrid® – a combination Secugrid/Geotextile composite product.
Combigrid delivers reinforcement, filtration, separation and drainage all in
one product. This product is predominantly used in conjunction with soft and
low ‘California
Bearing Ratio’ (CBR) soil, where reinforcing in
combination with separation and filtration is needed. For example, in base and
embankment reinforcement and load transfer platforms of pile caps.
Other Naue Geosynthetics products available locally from Fibertex
include Bentofix Geosynthetic Clay Liners (GCLs), which are composite
materials, designed for use as efficient sealing barriers in various
applications, including landfill projects.
Fibertex South Africa supplies an extensive range of
environmentally-friendly geosynthetic products from its KwaZulu-Natal, Gauteng
and Western Cape facilities that encompasses nonwoven and woven geotextiles,
gabions and mattresses, drainage pipes and fittings and erosion control and
cellular confinement solutions.
The company also supplies soil reinforcing products, including
geogrids and geocells, as well as geosynthetic clay liners and geomembranes as
part of composite lining systems used in modern landfills and for other
environmental protection applications
