Combigrid® is a flat composite geogrid from the
Secugrid® Q or R product series. It has
firmly welded junctions and a centrally
integrated Secutex® nonwoven
component for reinforcing, separating
and filter applications.
Combigrid® combines all the requirements
of a variety of properties
in one single product. For this reason,
the main area of use for Combigrid® is
on weak subsoils where, in addition
to reinforcement, filter and separating
properties are required. As a rule,
this means subsoils with a CBR value
of less than 3%. Thus, the areas of
application for Combigrid® are to be
found in the reinforcement of base
courses, foundations, access roads,
pipeline trenches and throughout the
road building sector. The range of
products available incorporates different
degrees of tensile strength and
nonwoven components and covers a
variety of applications. Combigrid® is
thus an all-purpose product for universal
applications.
It is available in polypropylene
(PP) or in polyester (PET), depending
on project requirements. It is suitable
for the use in all natural environments.
Combigrid® geogrids are
superior soil reinforcement elements
because they resist service tensile
force loading with very low elongation.
This results in an immediate
force connection and interlocking
with the fill soil without primary deformation.
The monolithic flat polymer
bars used to make Combigrid® are
extremely robust and have excellent
chemical resistance, as well as an
extremely good weather resistance as
shown in the Global UV test. The
Secutex® separating, nonwoven geotextile
which is firmly integrated between
the reinforcing bars features
efficient long-term filter stability and
high robustness, reasons why Combigrid® geogrids have been approved by
the Federal Railway Office for use in
earthworks for railway constructions.
An excellent example of two single
high-quality components combined in
one product - Combigrid®.
Combigrid® is extremely quick and
easy to install, thus reducing installation
costs considerably. System solutions
using Combigrid® can reduce
the thickness of the base course of
roads and often avoid the necessity to
replace weak subsoils thus conserving
resources and economizing costs. For
the reinforcement of the bearing
layer, a calculation disk can be
requested to determine the right
Combigrid®/Secugrid® type.
Combigrid® can be installed during
virtually all weather conditions without
heavy equipment or special construction
techniques. Panels are
joined and continuity is assured with
simple overlaps. Standard cutting
tools can be used for on-site trimming,
and for steep slopes various
eometrical shapes can be formed
where necessary.
Combigrid® is an all-purpose composite
product suitable for use in a
variety of reinforcement, separation
and filtration applications. Combigrid® is extremely robust, resistant
and durable allowing a cost-efficient
alternative to other construction
methods in all sectors of civil and
environmental engineering. Combigrid® provides the user with a technically
sophisticated product to fulfil
the requirements in even the most
unusual projects.
