Geogrids

The Pietrucha Group is the manufacturer of the PolGrid geogrids, specialized geosynthetics widely used in the civil engineering projects to stabilize and reinforce land or to separate the substrate layers with varying graining. The solid, integral structure of PolGrid products and four-sided openings function considerably better with  aggregate than flat profile grids or geogrids with rounded openings. Geogrids are used  in transport construction projects and other geothechnical works. PolGrid products are quick and easy to install and allow for the reduction of the use of materials, thus saving investment costs and saving time.

Technology

The key feature of the PolGrid products is their rigid construction with stiff and integrated nods. The structure has no interconnecting junctions and the strength of the geogrid node is equal to the strength of the rib. PolGrid is manufactured on an automated 130 meter long technological line and it involves extruding a thermoplastic plate of high strength polypropylene (PP), perforating the calibrated plate and finally mechanical orientation (by stretching) in both directions. The manufacturing technology as well as the used materials guarantee high quality of the product and its unvarying technical parameters.

The quality of the PolGrid geosynthetics is monitored at an in-house laboratory under the supervision of the British Textile Technology Group as well as the Süddeutsche Kunstoff-Zentrum, one of the world’s most acclaimed institutions certifying geotechnical products. The physio-mechanical parameters of the geogrids are subject to continuous monitoring by an in-house research center. The Pietrucha Group is also a member of the International Geosynthetic Society.
