High Strength Geogrid Secugrid®-HS

Secugrid® HS are high strength geogrids

They are laid geogrids made of high tenacity polyester filaments with an extruded polyethylene protective coating and welded junctions. Secugrid® HS combines high tensile strength and low creep tendency with extreme robustness and resistance. Secugrid® HS was developed specifically for geotechnical applications in earthworks where tensile strengths of more than 400 kN/m are required.

Typical applications for Secugrid® HS Geogrids

Flood Protection with Secugrid HS - Gratz

Advantages for your project:

  • Increased stability of embankments due to high tensile strengths of up to 1200 kN/m
  • Faster construction progress due to shorter consolidation periods
  • Mitigation of differential settlements in case of a heterogeneous subsoil
  • Long-term stability (low creep tendency/high long-term resistance)

Load transfer platforms over piles

Secugrid HS enables access to Europes second biggest waterway junction - Weserschleuse Minden

Advantages for your project:

  • Larger pile spacing (due to high tensile strength)
  • Absorption of lateral thrust forces eliminates the need for raking piles
  • Mitigation of differential settlements
  • No waiting time for consolidation processes

Bridging of sinkholes and mining voids

Secugrid HS Bridging of sinkholes and mining voids

Advantages for your project:

  • Reduced risk of accidents in the event of occurring sinkholes/mining voids
  • Increased safety due to high ductility of the system
  • Economic and ecologic alternative to rigid raft foundations

Secugrid® HS product advantages

Secugrid® HS is the choice for all applications where high tensile strengths over a long service life is required. The selection of the polymers used in combination with the applied product technology guarantees a robust and durable reinforcement product.

Low creep tendency

All geosynthetics that are exposed to permanent loads experience loss of tensile strength over time as a result of creep effects. The degree of tensile strength reduction depends on the stress level, time, temperature and molecular composition of the polymer used. Table 1 shows a comparison between the usual reduction factors for polymer-specific geosynthetics (see EBGEO 2010) and the result for Secugrid® HS. The comparison documents the high quality of Secugrid® HS with regard to its very low creep tendency.

Robust against damage during installation

Installation of soil and the subsequent compaction mean high stresses for geogrids during the installation phase. Robust reinforcement products largely retain their strength during installation. The very high robustness of Secugrid® HS was documented in field trials. For Secugrid® HS 1200/100 R6, for example, a reduction factor of only 1.03 can be expected when installed below crushed stone (d85 < 35 mm).

        Secugrid® geogrids for soil stabilisation and reinforcement


        Secugrid® geogrids for soil stabilisation and reinforcement. Secugrid® is a structurally sound and stable geogrid for soil reinforcement, manufactured of extruded and drawn polypropylene (PP) bars, laid and welded solid together.



        Combigrid® is composite of a laid geogrid made of stretched, monolithic flat bars with welded junctions and a mechanical bonded geotextile welded within the geogrid structure.
