20kn 30kn 40kn Grid Mesh Biaxial Polypropylene PP Plastic Geogrid for Road Reinforcement
Product Description
PP/Plastic Biaxial Geogrid is made of polypropylene. It is produced through through several processes: extruding, punching, heating, longitudinal stretching and transverse stretching. It has a high tensile strength. After adding some percent of carbon black material, it makes the product good acid and alkali resistance, corrosion resistance and ageing resistance and durability.
PP/Plastic Biaxial Geogrid is widely used for Improving the bearing capacity of foundation, Preventing cracking and subsiding. It is an economic construction material which is convenient to construct, reducing cost and maintaining expense.

Application:
It reinforces old asphalt concrete road surface as well as asphalt layer, and prevents damage;
It is used for rebuilding cement concrete road surface into composite road surface and restraining reflection caused by block contraction;
It is used in road expansion and improvement project, control cracks caused by old and new combination position or by uneven sedimentation;
It is used in soft soil base reinforcement treatment. It is favorable for soft soil water separation and concretion,restrains sedimentation effectively, distributes stress uniformly and improves overall strength of road base;
It is sued for preventing contraction crack caused by new road semi-rigid base layer, and reinforces and prevents road surface crack caused by foundation crack reflection.
