Combined geogrid and geotextile

TerraGrid Core Composite

Achieve time savings when acquiring materials and overall quicker installations, thanks to TerraGrid Core Composite, an all-in-one solution that performs as both a biaxial geogrid and a geotextile. TerraGrid Core Composite consists of nonwoven geotextile thermally bonded to our popular TerraGrid Core range of geogrid. Available in 5.2m wide rolls as standard, it enables significant installation efficiencies to be achieved while reducing risks of failure.

Combination grid

Geogrids and geotextiles are often used together to provide reinforcement, separation, and filtration properties. This can be on projects such as haul roads, permanent roads, working platforms and compounds.

Developed with customer feedback and increased demand on construction materials in mind. TerraGrid Core Composite, combines all three functions into one, thermally bonded solution, providing significant time, labour and cost savings.

Effective reductions

Reduce your carbon emissions

We have a long history of providing excellent ground reinforcement, while also helping to reduce the amount of materials used.

Did you know that by using Geoworks' proven geogrids you can achieve savings of up to 50% in material required, due to the reduced amount of sub-base you need? This, combined with the separation and filtration properties in TerraGrid Core Composite, will provide the perfect solution for a wide range of applications.

With TerraGrid Core Composite you'll only need to ship, handle and install one single roll, offering a significant reduction in carbon during transport and handling versus using separate materials.

TerraGrid Core Composite Functions

Geosynthetics play an important role in improving soil characteristics in a wide range of civil engineering and infrastructure works. TerraGrid Core Composite provides cost and time-saving systems through the following functions:

Reinforcement

Provides additional strength to soils and aggregate layers, distributing loads more evenly. Can be used to reinforce and stabilise ground over weak and variable soils reducing rutting.

Separation

Prevents intermixing of soil layers. Different-sized particles are unable to mix, allowing water and gasses to pass through, creating a stronger surface to build on  with improved integrity.

Filtration

Restricts the movement of particles, retaining soil or aggregates while allowing water to pass through the soil .

Warner Brothers Studio

We helped Warner Brothers Studio and earthworks contractor Spadeoak to build new car parking areas as the land where they had previously built car parking on was being reclaimed for new buildings. Our MultiTrack 1000 nonwoven geotextile was laid on the formation to provide separation and filtration.

Helping to keep busy Suffolk road moving

Our technical team was contacted in August 2020 by contractor Interserve (now Tilbury Douglas), which made the improvements on behalf of Suffolk County Council, after the groundworker needed assistance mitigating issues caused by soft ground in the sub-formation near where the link road was being constructed – bringing the project to a halt.
