High Strength Geogrid SECUGRID® HS

Secugrid® HS is a laid and welded geogrid made of high tenacity polyester (PET) filaments with an extruded polyethylene (PE) protective coating used as reinforcement in many fields of civil engineering.

High tensile strength with this high strength geogrid

Secugrid® HS exhibits the primary strength in the machine direction with the ability to mobilise high tensile forces at low strains. The reinforcing bars are made of high tenacity polyester (PET) filaments with a co-extruded polyethylene (PE) protective coating. Where soil structures are to be constructed over soft foundations, Secugrid® HS high strength geogrids allow installation of fill layers without exceeding the low bearing capacity of the foundation soil.

Secugrid® HS products provide a structurally sound and uniaxial stable geogrid for long-term performance in mechanically stabilised earth (MSE) walls, segmental retaining walls (SRW), veneer reinforcement , basal reinforced embankments, load transfer platforms over piles, bridging of mining voids and sinkholes, construction over soft soil and other demanding soil reinforcement applications where extraordinary high uniaxial strength is required.

High strength geogrid advantages

  • High tensile strength
  • Very good tensile modulus
  • Very good stress strain behavior
  • Low creep strain
  • High creep rupture strength
  • Robust & durable extruded polyethylene protective coating
  • Very good chemical resistance
  • High resistance against biological attack
  • High resistance against UV radiation
  • High resistance against hydrolysis (high pH)
  • Robust against installation damage
  • Quick and easy to install due to 4.75m wide rolls

Typical applications for Secugrid® HS (High Strength) include:

Basal reinforced embankments on soft soil

Secugrid® HS is installed at the base of the embankment to avoid failure through excessive shear deformation and bearing capacity failure in the foundation.

Secugrid® HS offers the following advantages:NAUE_ICON_EMBANKMENT_1

  • Larger embankment heights possible
  • Mitigation of differential settlements
  • Accelerated staged construction (consolidation)
  • Reduced overall project costs

Load transfer platform (LTP) over piles

In this application, Secugrid® HS is installed at the base of an embankment within a load transfer platform (LTP) over piles to prevent settlements and failure through excessive shear deformation and bearing capacity failure in the foundation.

The high strength geogrid Secugrid® HS offers the following advantages:NAUE_ICON_EMBANKMENT_2

  • No excavation and soil replacement required
  • Increase of pile spacing (reduced number of piles)
  • Mitigation of differential settlements
  • No waiting time for consolidation
  • Rapid construction
  • Reduced overall project costs

Bridging of voids and sinkholes

A layer of Secugrid® HS is installed at the base of an embankment to prevent total collapse of the foundation resulting from voids occurring below the ground surface. Subterranean voids can arise from natural processes (e.g. soil erosion in karstic areas) or from man-made processes (e.g. ground water pumping or underground mining).

Secugrid® HS (High Strength) offers the following advantages:NAUE_ICON_EMBANKMENT_3

  • Economic alternative to rigid raft foundations
  • Mitigation of differential settlement
  • Rapid construction
  • Reduced overall project costs
