What is Geogrid?
Plastic geogrid is a square or rectangular polymer mesh formed by
stretching. It can be divided into unidirectional stretching and
biaxial stretching according to the different stretching directions
during its manufacture. It is punched on the extruded polymer plate
(most of the raw materials are polypropylene or high-density
polyethylene), and then directionally stretched under heating
conditions. single
The upward stretching grid is only made by stretching along the
length of the plate, and biaxial stretching
The grating is made by stretching the unidirectional stretching
grating in the direction perpendicular to its length.

Applications:
Biaxial tensile plastic geogrid is applicable to the reinforcement of various dikes and subgrade, slope protection, tunnel wall reinforcement, permanent bearing foundation reinforcement of large airports, parking lots, docks and freight yards, etc. a. Bidirectional geogrid is used to increase the bearing capacity of subgrade and prolong the service life of subgrade. b. Bidirectional geogrid is used to prevent road (ground) surface collapse or crack, and keep the ground beautiful and tidy. c. The biaxial geogrid is used for convenient construction, saving time and labor, shortening the construction period and reducing the maintenance cost. d. Bidirectional geogrids are used to prevent cracks in culverts. e. Bidirectional geogrid is used to strengthen soil slope and prevent water and soil loss. f. Bidirectional geogrid is used to reduce the thickness of cushion and save cost. g. Bidirectional geogrid is used to support the stability of grass planting mesh pad on the slope and greening environment.
Construction method
Construction method of biaxial geogrid: excavate the subgrade bed, set sand cushion (height difference not more than 10 cm), roll it into a platform, and lay the grid. The longitudinal axis shall be consistent with the main stress direction. The longitudinal lap shall be 20 cm and the transverse lap shall be 10 cm. The lap joint shall be bound with plastic tape, and the paved grid shall be fixed to the ground with U-nails every two meters, The geogrid laid shall be backfilled with soil materials in time, and the number of layers of geogrid laid depends on the technical requirements.
