What are geogrids and what are their uses?

Geogrids are extremely strong structures with regular, rectangular meshes. They are used mainly in the construction industry, with more and more applications and constantly growing popularity in this field. Their primary purpose is to reinforce soil and road surfaces. Thanks to even distribution of the load to which the surface is subjected, they provide greater stability and increase strength. They also protect the surface against mechanical damage, which effectively extends its life.

How do geogrids work and how are they built?

Geogrids are made of various materials, and the choice of material has a huge impact on their properties. Road geogrids produced by our plant in Pabianice are made of glass fibres or glass and carbon fibres. Raw materials, mesh size, strength, and maximum elongation are selected depending on the application.

What are geogrids used for?

There are more and more uses of geogrids in the construction industry. As mentioned above, they are most often used to reinforce soil and road surfaces and as a subbase for roads and tracks, resulting in less frequent damage and repairs. Geogrids are also used to stabilise steep surfaces, e.g. embankments. They strengthen the structure of embankments and prevent sliding.

Geogrids are divided into one-way and two-way geogrids. They differ in the adaptation to specific applications: one-way geogrids perform best at longitudinal directions, and two way ones in both longitudinal and transverse directions. The former are mainly used to reinforce escarpments, embankments, and landslides. The latter can cope very well with roads, tracks, and surfaces with less predictable movement, such as car parks.
