Combigrid
Secugrid geogrid bonded to Secutex non-woven geotextile: reinforcement, separation and filtration in one layer. PP and PET series, 20/20–80/80 kN/m. For access roads, mine haul roads, working platforms and stockpile areas.
What is Combigrid®?
Combigrid® geogrids are the next generation of geogrids produced with state-of-the-art manufacturing technology, unlike any other geogrid on the marketplace today. The reinforcement element is a highly oriented polypropylene (PP) or polyester (PET) bar that is uniformly extruded and drawn to achieve a high modulus and strength at low elongations.
The Secutex® non-woven geotextile is placed between the Secugrid® bars during the manufacturing process and is firmly bonded between the reinforcement bars using NAUE's patented welding technology — producing a structurally sound and stable composite product.
Combigrid® is mainly used in conjunction with soft and low CBR soils where soil reinforcement combined with separation and filtration is needed — such as base reinforcement, embankment reinforcement, and pile cap platforms.
Key features
- 4 Functions in 1 ProductCombigrid® simultaneously provides reinforcement, stabilisation, filtration and separation — eliminating the need for a separate geotextile filter layer and reducing total aggregate thickness.
- High Strength at Low StrainsCombigrid® delivers excellent tensile strength at 2% working strain — the critical range for real-world soil performance. Very high radial secant stiffness values ensure immediate load transfer to the reinforcement layer.
- Soil Separation & Filter StabilityThe three-dimensional fibre matrix of the needle-punched Secutex® non-woven acts as a permanent separation layer between different grain size soils, ensuring long-term filter stability — especially recommended for subsoils with CBR less than 3%.
- Quick & Easy InstallationAvailable in 4.75 m wide rolls for fast coverage. Immediate interlocking with cover aggregate upon placement. CE marked and ISO 9001 certified for quality assurance.
