Polypropylene Geogrid
This is a category of geosynthetics that we obtain from the polymer propylene, with an extensive structural and infrastructural uses. They offer many benefits in construction, and soli retracement projects. Depending on the specific applications, you can choose a suitable cross-section design and structure.
Polypropylene Geogrid Structure
- Junction – It is the intersection point between the longitudinal and transverse ribs that offers structural stability.
- Aperture – This is a large open space between the adjacently lying sets of the transverse and longitudinal ribs.
- Longitudinal ribs – These are ribs that stretch parallel to the direction of the machine.
- Transverse ribs – They are ribs that stretch perpendicular to the machine’s direction.
Types of PP Geogrid
Polypropylene Uniaxial Geogrid – It is a type of Polypropylene geogrid that stretches along only the longitudinal direction.
Polypropylene Biaxial Geogrid – This is a geogrid type with a formulation of high polymer concentration. It stretches the both of its longitudinal and transverse direction in an equal measure of stress.
Polypropylene Triaxial Geogrid – It results from the punching process of a polypropylene sheet to produce a multiple-equilateral directional structure in triangular shapes.
Benefits of Polypropylene Geogrid
Highly Versatile Material
They contain properties that allow combination with other facing elements to create variable aesthetics.
Offer Optimal Reinforcement
These specific Geogrids have great creeping properties that enhance the stabilization of backfill in retaining walls.
Improve Roadways Performance
The polypropylene biaxial Geogrids have high tensile strength offering base stabilization on roads.
Offers Subgrade Improvement
Polypropylene biaxial Geogrids provide stable foundations to permanent roads due to their ability to widely distribute loads in an area.
Controls Rutting Effect
The polypropylene biaxial Geogrids have high tensile strength to ensure maximum subgrade power in both directions. This prevents rutting which results from heavy trafficking.
Supports Dykes and Berms
There is proper Interlocking of fill materials with biaxial geogrid apertures to obtain good confinement of the layers under reinforcement.
Applications of Polypropylene Geogrid
The polypropylene biaxial geogrid have high tensile strength and good retention resistance to ensure maximum subgrade power in both directions. This ensures the round has maximum strength to prevent rutting which results from heavy loads transportation.
Polypropylene Geogrid offers stability to the wall by creating a fill zone which provides mass uniformity behind the structure.
These Geogrids provide stability to the unbound layers that in turn creates a strong foundation for the pavement.
The geogrids offer base reinforcement through the reduction of aggregate layers thickness which improves the roads performance life.
