Naue’s Geogrid Products:

Robust polyester Secugrid® geogrids (pet) for stabilising a road over soft subsoil

Secugrid®

Laid geogrids made of stretched, monolithic polyester (PET) or polypropylene (PP) flat or profile bars with welded junctions. Secugrid® geogrids combine high stiffness and low creep tendency with extreme robustness.

Combigrid® nonwoven geogrids combination for minimising the base layer in construction roads

Combigrid®

Combigrid® is a composite of a laid geogrid made of stretched, monolithic flat bars with welded junctions and a mechanically bonded and calendered filter geotextile welded within the geogrid structure. Combigrid® is used for stabilisation and reinforcement of soils in many fields of infrastructure, environmental protection, and hydraulic engineering applications.

Secugrid® HS geogrids over piles for securing a bridge superstructure

Secugrid® HS

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.

FAQ

What are geogrids?

Geogrids are engineered geosynthetics primarily used for the stabilisation and reinforcement of soils. They are made from polymer materials such as polypropylene or polyester and feature a grid-like structure that provides high tensile strength and stiffness.

Naue’s geogrids, such as the Secugrid® range, are designed to increase the load-bearing capacity and strength of soils by distributing loads evenly and reducing soil deformation. These properties make them ideal for applications in road construction, railway construction, dam and dike construction, as well as for general soil stabilisation and erosion control.

In addition to their mechanical performance, Naue geogrids offer significant advantages in terms of installation efficiency and durability. Their high resistance to chemical and biological degradation, combined with excellent long-term creep behaviour, ensures a reliable and maintenance-free solution for decades. Moreover, their ease of handling and quick installation help reduce construction time and costs, making them a sustainable and economical choice for infrastructure and geotechnical projects.

This Naue Products are utilised in a wide range of construction and infrastructure projects, including:

  • Road and pavement construction
  • Railway trackbed stabilisation
  • Embankments, dams and dykes
  • Ground improvement and foundation support
  • Erosion control
  • Industrial and heavy-duty storage yards

  • High tensile stiffness and low creep deformation
  • Chemical and biological resistance
  • Quick and simple installation
  • Reduction of required fill material, such as aggregate
  • Improved bearing capacity and service life of structures

  • Uniaxial geogrids provide reinforcement in one direction only, making them suitable for applications such as retaining structures.
  • Biaxial geogrids offer tensile strength in two directions, ideal for subgrade stabilisation under roadways and foundations.

Geogrids are typically laid flat over a prepared subgrade with a defined overlap, and without tension. The fill material is then placed and compacted over the grid. Detailed installation instructions can be obtained from Naue’s engineering support or technical documentation.

Naue are primarily composed of:

  • Polypropylene (PP) – known for high stiffness and chemical resistance
  • Polyester (PET) – offers excellent long-term tensile strength and dimensional stability
  • Polyethylene (PE) – used as a protective coating in specific products like Secugrid® HS

Naue geogrids comply with national and international quality and testing standards and are certified by recognised bodies such as the BBA approval from the British Board of Agrément, testing according to ASTM standards by the American Society for Testing and Materials, the CE marking in accordance with the European Construction Products Regulation via the European Commission, specific product evaluations by the BAM – Federal Institute for Materials Research and Testing, and compliance with international standards set by the ISO – International Organization for Standardization.

The Role of Geogrids in Geotechnics and Construction

Naue Geogrids play an essential role in modern geotechnics and construction. Made from a network of polymers, they are employed in various sectors such as road construction, slope stabilisation, and foundation engineering. Their primary function is to stabilise soft or unstable substrates and reinforce the subgrade.

By locking the fill material within their structure, Naue geogrids improve load distribution, reduce settlements, and increase the soil’s load-bearing capacity. They effectively contribute to erosion control and the prevention of soil slippage. Utilising geogrids can avoid costly soil replacement works and shorten construction times, making them a cost-efficient and environmentally friendly alternative in the contemporary construction industry
