PP weld geogrid PP

short description:

PP weld geogrid is a new type of environmentally friendly building material that is reinforced with reinforced fibers in polyethylene and polypropylene tensile tapes, and then welded into a “#” structure. PP welded geogrid is an upgraded product of traditional steel-plastic geogrid, which improves the shortcomings of traditional geogrids such as low peeling force, easy cracking of welding spots, and little anti-side shift.

Product Description

Product Specification：
Tensile Strength：25000-150000N/m；Elongation at Yield ：12-13%；Grid Size：100~150mm；Width：4～6m.
Product Features：
1. PP weld geogrid has the properties of high strength, low elongation (breaking elongation not more than 12%), and its creep value is very small.
2. The grid is used to reinforce the foundation, improve the bearing capacity, reduce the uneven settlement, and resist the formation of the soil failure surface.
3. PP weld geogrid has good flexibility as the material is continuously stretched by strong tension and double-sided clamping of transverse rib belts, the performance of the geogrid is still maintained even if it is cracked.
4. The biaxial geogrid type uses polypropylene or other advanced materials and adds anti-ultraviolet additives. After extruding and stretching, it has great tensile strength in both vertical and horizontal directions, which is suitable for large-area, long-term bearing roadbed reinforcement.

Application Scenarios

It can be widely used in the reinforcement of weak foundations in the construction of highways, railways, bridge abutments, docks, slope protection, slag yards and other construction fields, as well as retaining walls and pavement crack resistance projects.
