SECUGRID® 2017-11-30T16:09:08+00:00



is a structurally sound and stable geogrid for soil reinforcement, manufactured of extruded and drawn bars, laid and welded solid together.


Secugrid® geogrids provide tensile reinforcement for base courses in railway and highway foundation engineering, steep sided soil em bank ments and retaining walls, foundation reinforcement of earth embankments, load transfer of overlying soil masses, spanning voids and sink holes, sludge lagoon closures, trench covers and beds. With the available tensile strengths Secugrid® is suitable for the most demanding projects. In addition to our standard geogrid products, we also manufacture Combigrid® – a high strength compo site product comprising a geogrid and nonwoven geotextile.

  • CE marked


Secugrid® 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 Secugrid® are extremely robust and have excellent chemical resistance. Secugrid® is manufactured under the EN ISO 9001 : 2000 regime, ensuring its uniformity and high quality. It has passed the inspection of numerous recognised materials testing institutes and has been approved by the Federal Railway Agency for use in earth structures for railway engineering.


Engineering system solutions using Secugrid® geogrids can save natural mineral resources by reducing base course thickness for pavements. For this application a calculation disk can be requested to determine the right Secugrid® type. As Secugrid® is easy to handle, large quantities can be installed quickly with minimal demand on labour resources and lower installation costs.


Secugrid® 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 sided slopes, various geometrical shapes can be formed where needed to best fit the location.


The Secugrid® geogrid products are extremely robust and easily installed, providing an economical alternative solution to traditional construction methods. The wide range of products, including both uniaxial and biaxial (R and Q type) geogrids, makes Secugrid® an ideal structural component in practically all fields of civil and environmental engineering. These high-perfor mance, low cost products provide simple, cost effective soil reinforcement, by strengthening naturally unstable soil and subsoil to withstand the loading conditions imposed by modern engineering demands.

    SecuCalc Calculation Disk

    For base course calculations NAUE has generated a “Top Tool Calculation Disk”.
    By integrating Secugrid® or Combigrid® geogrids into the bearing layer the total thickness of the design can be reduced, thus creating a cost saving potential.

    1. Place the two red arrows against each other for the selected EV2top or CBRtop value.
    2. Turn the disk anti-clockwise until you have reached your selected CBRsub value of the subsoil. Should this value be between two values it is recommended to select the lower value.
    3. On the left side of the disk you can compare the thickness of the bearing layer unreinforced and Secugrid® reinforced for two soil types. Should the reinforced value be red we recommend to install in the middle of the bearing layer an intermediate Secugrid® reinforcement.
    4. On the right side of the disk you can see the thickness saving with Secugrid® reinforcement for the three soil types. Additionally we recommend a Secugrid® (X) or Combigrid (X*) type for the selected condition, which should be installed between the subsoil and the bearing layer, resp. if required as an intermediate reinforcement (see note 3) in the middle of the bearing layer (red X in outside column).
    5. Please follow the latest Secugrid® installation guidelines.

    X* – up to CBRsub 3% it is recommended to use Combigrid® to improve the filter stability:
    Combigrid® 30/30 Q1/151GRK 3
    Combigrid® 40/40 Q1/151GRK 3
    Combigrid® 60/60 Q1/151GRK 3

    X* – up to <= 15NM/m² EV2 top it is recommended to use Combigrid® to improve the filter stability:
    Combigrid® 30/30 Q1/151GRK 3 or Q6/R156
    Combigrid® 40/40 Q1/151GRK 3 or Q6/R156
    Combigrid® 60/60 Q1/151GRK 3 or Q6/R156
