COMBIGRID®

COMBIGRID®

is a composite product of a Secugrid® geogrid, with a needle-punched Secutex® nonwoven geotextile firmly welded between the reinforcement bars, for soil stabilisation, separation and filtration applications.

COMBIGRID® IS MULTIFUNCTIONAL

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.

ADVANTAGES OF COMBIGRID®

  • reinforcement, filtration, separation and drainage in just one product, reducing aggregate thickness
  • firmly bonded composite product
  • very high strength at low strains
  • immediate interlocking with cover aggregate
  • high resistance against installation damage
  • nonwoven geotextile firmly bonded between uniformly extruded PP or PET bars
  • high resistance against biological and chemical degradation
  • 4.75 m wide rolls
  • quick and easy to install
  • ISO 9001 certified
  • CE marked

COMBIGRID® IS SAFE

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 inter locking 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 wea ther resistance as shown in the Global UV test. The Secutex® separating, nonwoven geotextile which is firmly integrated be tween 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 ECONOMICAL

Combigrid® is extremely quick and easy to install, thus reducing installa tion 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 economising costs. For the reinforcement of the bearing layer, a calculation disk can be requested to determine the right Combigrid®/Secugrid® type.

COMBIGRID® IS SIMPLE

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 geometrical shapes can be formed where necessary.

CONCLUSION

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.
