Geogrid for soil stabilisation and ground reinforcement

Geogrids are essential geosynthetic materials engineered to reinforce soil and improve ground performance in civil construction projects. These high-strength grids enhance load distribution, prevent ground movement, and support the stability of infrastructure such as roads, retaining walls, and embankments.

Ideal for both temporary and permanent applications, geogrids are a cost-effective and environmentally responsible solution for improving ground conditions and performance in challenging site environments.

What is a geogrid and how does it work?

Geogrids are polymer-based mesh structures designed to interact with soil and aggregates, providing reinforcement through tensile strength and interlock. When placed within or beneath granular layers, geogrids reduce lateral displacement, facilitate compaction, and enhance load-bearing capacity.

They are particularly effective in stabilising weak or variable soils, reducing the need for over-excavation and thick base layers.

Types of Geogrids for Civil and Construction Projects

Choosing the right type of geogrid is key to achieving optimal performance. Our range includes:

Biaxial Geogrid

Engineered for load support in two directions (longitudinal and transverse), biaxial geogrids are ideal for subgrade stabilisation, pavement reinforcement, and base layer improvement. They enhance aggregate confinement and reduce rutting in road construction.

Triaxial or Multiaxial Geogrids

With a triangular aperture design, triaxial geogrids distribute forces in multiple directions for superior stabilisation. They are perfect for working platforms, haul roads and access tracks built over soft or unstable ground.

High-Strength Uniaxial Geogrids

Designed for use in reinforced soil structures, uniaxial geogrids deliver exceptional tensile strength in one direction. They are used in the construction of retaining walls, steep slopes, bridge abutments and embankments on soft soils.

Key applications of Geogrid

Geogrids are trusted by engineers and contractors across multiple sectors for their versatility and strength. Common applications include:

Subgrade and Pavement Stabilisation

Reinforce weak subgrades and reduce maintenance in roads, highways and car parks.

Retaining Wall and Slope Reinforcement

Provide internal stability for soil structures in retaining walls and slope reinforcement, which enables steeper, more space-efficient designs.

Working Platforms for Heavy Equipment

Create stable, load-bearing platforms for cranes and construction machinery.

Embankments Over Soft Soils

Support embankments and causeways in challenging ground conditions, preventing differential settlement.

Benefits of Using Geogrids for Soil Reinforcement

What are geogrids and how do they reinforce construction?

Geogrids are geosynthetic materials used for reinforcement and stabilizing soil structures. They have high tensile strength and a higher elastic modulus than soil, allowing them to distribute loads more effectively and provide better reinforcement in construction applications than they otherwise would. Geogrids can be used in soil reinforcement, reinforcement of retaining walls, slope stabilization, etc. Geogrids are formed by intersecting grids of elements extending in two directions, one in the machine direction (longitudinal) and the other in the transverse (or cross-machine) direction, forming the shape of the apertures. These apertures vary depending on application and manufacturer’s specifications. Geogrids are made of different materials such as polyester, polyvinyl alcohol, polyethylene, or polypropylene. At Strata Geosystems, we manufacture PET geogrids.

Today, geogrids are extensively utilized across a diverse range of civil engineering projects, spanning from power generation and soil stabilization to erosion control and roadway improvement. In addressing the challenges inherent in land construction, geogrids emerge as a natural and cost-effective solution for subgrade development. Civil engineers must consider various factors depending on the land being developed. At Strata Geosystems, we are committed to providing assistance throughout the planning and consultation process. Some common applications of geogrids are:

1. Embankments over soft soils: Geogrids are used to provide reinforcement and stabilisation for embankments built over soft soils. By stabilising the subgrade, confining them, they minimise lateral movement and provide strength and better load bearing to weak soil areas.

2. Erosion control:  They provide structural reinforcement to the soil mass on a slope. This stabilized soil, once vegetated, is far more resistant to surface erosion caused by rainwater runoff.

3. Roadway improvements: Geogrids are used in road and pavement construction to improve the mechanical properties of the subgrade soil. They help distribute traffic loads, reduce rutting and cracking, and extend the lifespan of the road infrastructure.

4. Reinforced steep slopes: Geogrids are applied to stabilize and reinforce steep slopes, providing stability and preventing soil erosion. At Strata Geosystems, our geogrids are made from polyester or PET which is ideal for soil interlocking under most topographic conditions. This confinement within the apertures provides slope stability.

5. Retaining walls: When placed horizontally within the soil backfill, a geogrid reinforces the backfill, creating a composite soil mass that can stand at a steeper angle and reduces the lateral pressure on the retaining wall facing. This may allow for the use of on-site fill material instead of more expensive imported fill.

6. Landfill construction: Geogrids find application in landfill construction for reinforcing steep slopes, stabilizing the veneer cover soils over geomembranes, and providing foundational support for landfill expansions.

7. Slope stabilization: Ideally used to minimize slope deformation and stability while providing a natural and economical solution for slope stabilisation.

8. Paving overlay reinforcement: They are used to reinforce asphalt and concrete pavements, reducing construction costs and extending the service life of the pavements.

Geogrids have various applications in construction due to their unique properties. Given their construction, some common uses of geogrids include:

1. Building firm working surfaces over soft ground conditions by providing confinement to the aggregate layer through the interlocking of particles within the geogrid apertures, thus improving the load-bearing capacity of the soil. Soft soil compresses under traffic or structural loads, causing uneven surfaces and structural damage. Geogrids reduce settlement in subgrades by interlocking soil particles. They distribute loads evenly and enhance shear strength.

2. Enhancing a pavement’s service life by reducing iterative maintenance cost. Geogrids can help with reducing rutting, cracking and other typical issues that occur with paved roads – be it asphalt or concrete.

3. Reducing the structural cross-section of both paved and unpaved roadways for a given service life. Geogrids reduce the stress transferred to the subgrade by improving the shear strength of the reinforced soil layer.

4. Reducing aggregate layer thickness in unpaved roadways by up to 50% without performance loss. 

5. Increasing the life of roads and pavements by reducing annual maintenance budgets for asphalt course replacement by over 50%.

6. Improving the bearing capacity of weak subgrades, providing enhanced safety and seismic durability by stabilising slopes and increasing soil strength. This is of particular value  in zones that are prone to soil movement due to erosion. Geogrids can also aid with erosion control by locking soil particles. 

7. Reinforcement of retaining walls, embankments, composite structures, foundations for roadbeds, railroad truck beds, airport runways, construction haul roads, working platforms on weak subgrades, and parking lots.

2. Kohima Bypass Road, Nagaland:

Strata Geosystems was involved in the implementation of a durable and flexible pavement solution using StrataGrid biaxial pavement. The project aimed to address the challenges of constructing a high-traffic pavement in the hilly and inaccessible regions of North-East India. To achieve this, a solution with StrataGrid biaxial was chosen over conventional methods due to its ability to reduce pavement thickness, minimize the use of natural materials, and decrease maintenance frequency. The design considered a subgrade California Bearing Ratio (CBR) of 10% and a traffic intensity of 50 MSA, with two layers of SGB Grid incorporated within the Wet Mix Macadam (WMM) and granular sub-base. The confining effect of the SGB Grid helped stabilize the pavement section under traffic loads, reducing vertical and lateral movement of aggregates. This innovative solution facilitated easy installation, conservation of natural materials, improved fatigue and rutting design life, and enabled economical and fast construction, showcasing the effectiveness of Strata’s geotechnical products in infrastructure development
