Geogrid-Based Cost-Effective and Sustainable Wind Farm Development

geosynthetic reinforcement in wind farm


Subsidies and federal energy policies get most of the headlines, but with the formulating size of wind turbines and the scale of wind farms, rare locations can be developed without a soil-underpinning procedure. Geosynthetics produce a tough base for construction works and long-term access to wind energy areas.

On-shore wind turbine hub sizes increasingly crest 100m, and some are moving toward 150m. heading towards 150m. Rotor diameters can surpass 125m. While multiple turbines are even in the 3 MW range, big turbines are catching 7.5 – 8+ MW. Hub sizes are effectively twice as tall as just 10 years ago and the power outcome is four times greater.

Off-shore turbines, which are garnering enormous curiosity now, are being designed even larger.

For on-shore applications, helping the massive weight of a turbine (more than 200 tons) frequently requires geosynthetics, as much to support construction (e.g., cranes) as to deliver long-term soil resilience and responsible access.


Wind farms need space, of course, and it is not unusual for the soils in these more remote locations to need stabilization technologies to sustain high loads. The larger the wind farm array, the more highways will need to be created between the turbines. Miles of the road may be required on a utility-scale site.

Efficiency is emphasized in these road networks. A developer wants to minimize the number of roadways to be created. Also, the developer wants to evade having to use public roads, as much as feasible, between turbines.

In an optimally developed site, once crews are operating on a turbine they will not be required to “leave” the site to build the next. They expect to shift cranes and other key tools from one dwelling to the next without general roadways, as penetrating them with such big loads may need special permitting or tools disassembly.

Crane axles must take loads over 200,000 lb.—not precisely what traditional roads are ranked for.

Furthermore, the efficiency and cost management of the on-site highways will depend on minimizing land disruption and staving off-road or functional safety issues, such as rutting. Hence, geosynthetic reinforcement is utilized to stabilize the subgrade sooner, which reduces the amount of soil required to be dug up and taken the place in road construction.


Geogrids and high-strength geotextiles deliver enormous gifts to wind farm road and crane pad construction. They expand subgrade and flexural immobility. They reduce vertical and shear stresses They minimize or deter migration of penalties, lessen aggregate need, and minimize excavation.

All of these advantages not only make wind energy sites more scrimping but in many conditions simply possible.

Instances of this utility are multiple and able to be found throughout the world’s wind energy infrastructure.

Our geogrids have been utilized in several wind energy applications too. New York’s High Sheldon Wind Farm, for example, generates roughly 130 MW of power to support 60,000+ homes. The turbines have mainly been established on active agricultural lands, delivering side income for those operations while taking advantage of the elevated terrain in those areas to harness the area’s powerful winds. This delivers an incredible output and stimulates the efficient delivery of energy to the town.

The construction area loads in New York were around 5000 PSF, making geosynthetics a must. The 17-ft.-wide rolls assisted in expediting construction by decreasing the requirement to cut from additional rolls to achieve the essential width.

We have excelled in wind farm constructions internationally with amalgamated underpinning solutions like Combigrid®, which entrench a durable nonwoven geotextile within a high-strength Secugrid® geogrid. This provides soil divergence, filtration, and reinforcement characteristics in a single roll. This solution delivers numerous coatings of highway subgrade strength in a single coating for quick, significant ground improvement.

The company has also been entangled in geosynthetic-based scour security for major offshore breeze turbine installations.

Our high-strength reinforcement geosynthetics have been utilized to encourage the structure of wind farms internationally, incorporating the Netherlands’ tallest turbine: a 280-ton, 135m tall (hub height), 7.5 MW Enercon E-126. The tip elevation of the blade brings its length to 198m. Without the usage of geosynthetic reinforcement, it would not have been economically possible to construct the crane pad that was required to support the construction works.

The sustainability advantages of wind power rest not just in the renewability of the power source. Geosynthetic reinforcement, in reinforcing soil more efficiently, needs less land irritation than would be needed to construct wind farms without reinforcement. Greatly less soil must be engraved into to accomplish the appropriate access road and construction platform bearing stability when geosynthetic coatings are included. Aggregate fill may be decreased by up to 40%, and throughout acres of infrastructure, this symbolizes significant time, energy, and cost conservation in construction.

The carbon imprint of the on-site construction is greatly decreased, as is the transport to the site of heavy aggregate in contaminating trucks. By reinforcing soils efficiently, wind granges are assembled faster, more economically, and more endurable.
