Uniaxial Plastic Geogrid
Uniaxial Plastic Geogrid Introduction
Plastic uniaxial geogrid is manufactured from plastic materials
which may be high-density polypropylene or high-density
polyethylene (HDPE) resins by the hot extruding process to make the
resins into thin plates, the plates are punched into the regular
holes for the formation of desired grids, and then the punching
patterns are stretched longitudinally into the desired meshes to
develop designed tensile strength.

Uniaxial Plastic Geogrid Features
Uniaxial plastic geogrid is specially designed for soil
reinforcement. It is manufactured with High Density Polyethylene
resins or polypropylene, from the process of extruding and
longitudinal stretching. It has high tensile strength, excellent
interlock capacity, and low creep deformation. High quality
uniaxial plastic geogrid has High tensile strength, good creep
performance, convenient construction, low price.
Uniaxial Plastic Geogrid Application
1. Uniaxial plastic geogrid for sale used to reinforce weak
foundations.
2. Uniaxial plastic geogrid is used for reinforcing asphalt or
cement pavement.
3. Uniaxial plastic geogrid is used to reinforce embankment slope
and retaining wall.
4. Uniaxial plastic geogrid is used to reinforce river and sea
embankments.
5. Uniaxial plastic geogrid for sale is used to treat landfills.
Construction and laying method
Anchoring method: glass fiber geogrid without self-adhesive can be
used to strengthen asphalt concrete pavement and prevent reflection
cracks between pavement and pavement. However, it is better to lay
glass fiber geogrid first and then spray hot asphalt as bonding
oil. Construction personnel must wear gloves. The construction
method is as follows:
AH-70 or AH-90 heavy oil hot asphalt shall be selected as tack coat
oil. The specification and quality of tack coat oil shall comply
with technical specification for construction of highway asphalt
pavement (jtj032-94), and special vehicles shall be used for
spraying. The amount of tack coat oil per square meter is about
0.4kg-0.6kg.
When laying the glass fiber geogrid, the laying should be smooth
and tight. The transverse lap length should be 50-100 mm, and the
longitudinal lap length should be 150-200 mm. According to the
paving direction, the rear end should be pressed under the front
end.
Roll with rubber tyred roller.
The fixed iron sheet of 50? 0? 0? 3 mm should be flat without
warping angle, and the surrounding should be chamfered. 2 inch
steel nail (high quality cement nail) should be used
When the glass fiber geogrid is laid by nail fixation method, one
end of the geogrid is fixed on the lower structure with the asphalt
sprayed on it with fixed iron sheet and nails, and the nails can be
shot in by hammer or gun. Then the grid will be vertical
