What is Geogrid?
A geogrid is a geosynthetic made from a polymeric material.
Geogrids are formed by weaving or knitting intersecting ribs with
appropriate apertures (open spaces for the ribs to fit into).
Primarily, a geogrid is used for reinforcement applications in
various types of construction projects but can be used for
separation applications as well. They are open grids that allow the
soil to strike through the apertures and the two materials
interlock together to give composite behavior. There is a high
demand for geogrids in construction because they are good in
tension and have an increased ability to distribute loads across a
large area.

1. Increase the bearing capacity of subgrade and prolong the
service life of subgrade. 2. Prevent the road (ground) surface from
collapsing or cracking, and keep the ground beautiful and tidy. 3.
Convenient construction, time-saving and labor-saving, shorten the
construction period and reduce the maintenance cost. 4. Prevent
cracks in culverts. 5. Strengthen soil slope to prevent water and
soil loss. 6. Reduce the cushion thickness and save the cost. 7.
Support the stability and greening environment of grass planting
mesh pad on the slope. 8. It can replace metal mesh and be used for
false roof mesh in coal mine.
Features:
- Cost effective.
- High seam strength.
- Good erosion control.
- High in-plane stiffness.
- Good aperture stability.
- Excellent load distribution.
- Long term structural stability.
- Excellent corrosion resistance.

- Good corrosion resistant performance.
Applications:
Application of biaxial geogrid: biaxial plastic geogrid is used to
strengthen the subgrade of various highways and railways. Increase
the bearing capacity of subgrade and extend the service life of
subgrade; Prevent cracks on the pavement; Reduce repair costs;
Reduce the construction period. The biaxial geogrid is applicable
to the permanent foundation reinforcement of large parking lot and
wharf freight yard. Increase the bearing capacity of the foundation
and guard the ground against collapse, which can make the ground
elegant and neat; The construction is convenient, time-saving and
labor-saving. Bidirectional geogrid is applied to the secondary
reinforcement of soil slope reinforced by unidirectional tensile
plastic geogrid.
Construction method
The paving surface of the geogrid shall be relatively flat. After
the paving layer is accepted, in order to prevent longitudinal
deflection, first draw a white line or hang a line on the paving
layer according to the width, and then start paving, and then fix
the end of the grid with iron nails (8 nails per meter wide, fixed
at an even distance). After fixing the end of the grid, use the
paver to slowly clean the grid
Pull and pave forward. Manually tighten and straighten each 10m
long until one roll of grid is paved, and then pave the next roll.
The operation is the same as before. After paving one roll, use
6t-10t roller to roll it in the forward direction from the starting
point, (if it is paved on the middle surface course and leveling
course, it is better to use steel roller; if the grid is directly
paved on the concrete pavement, it is better to use rubber roller.)
Paving: take the roll length as the length of the section to be
paved. After the section to be paved with the grid is paved, check
the paving quality as a whole, and then pave the next section. When
the next section is paved, the grid and the grid can be overlapped
with a length of 10-15cm, fixed with iron nails or wooden wedges,
and then continue to pave the second section in the forward
direction, and so on. The operation requirements are the same as
before.
