The cellular geonet PINEMA BG, also known as the geogrid, is made of textured and perforated tapes made of high density polyethylene (HDPE). A set of tapes of a specific height that are combined by ultrasonic welding makes a system with the structure resembling a honeycomb. After filling with aggregate and compacting, it improves mechanical parameters of the aggregate. The spatial structure is designed to optimise the transmission of forces, reduce pressure, and minimise the costs necessary to achieve satisfying soil parameters on geotechnically difficult subsoils, or when the soil and water situation is not regulated. The geogrid PINEMA BG is manufactured in sections, in dimensions adjusted to the particular project. The HDPE is a soft and flexible material, easy to form so that the cells can be formed freely.
How the PINEMA BG geocell works
The PINEMA BG geocell system makes it possible to reduce the layers of the base course and to maintain and stabilise bluffs and embankments. The soil or the aggregate that fills the cells is blocked by the walls of the system so that it is more compacted. Apart from that the aggregate grains wedge between each other which improves the internal friction angle of the fill. The well compacted fill with the PINEMA BG geocell system counteracts the uneven settlement and reduces vertical forces. This modifies the thickness of the structural layer of the base course appropriately. Moreover, the use of the PINEMA BG geocell system helps to stop washing out the aggregate, which increases the stabilisation and improves the anti-erosion properties of bluffs and embankments.
