Action characteristics of composite geogrid near me products

1. The composite geogrid near me is laid between the foundation and the subbase, which is used to drain the ponding between the foundation and the subbase, block the capillary water, and effectively integrate into the edge drainage system.

This structure automatically shortens the drainage way of the foundation, greatly reduces the drainage time, and reduces the number of selected foundation materials (i.e. using materials with more fine materials and lower permeability). It can prolong the service life of the road.

2. Laying composite geogrid near me in the subbase can prevent the fine materials of subbase from entering into the subbase (i.e. to act as isolation). The aggregate base will enter the upper part of the geonet to a limited extent.

In this way, the composite geogrid near me also has a potential role in limiting the lateral movement of aggregate base. In this way, its role is similar to that of geogrid near me.

Generally speaking, the tensile strength and rigidity of the composite geogrid are better than those of many geogrids used for foundation reinforcement, which will improve the supporting capacity of the foundation.

3. After road aging and cracks are formed, most of the rainwater will enter the section. In this case, the composite geogrid is directly laid under the pavement to replace the drainage foundation.

The composite geogrid can collect moisture before it enters the foundation / subbase. Moreover, a layer of membrane can be wrapped on the bottom end of the composite geogrid to further prevent water from entering into the foundation.

For rigid road systems, this structure allows the design of roads with a higher coefficient of drainage CD. Another advantage of this structure is that it may make the concrete hydrated more evenly. This kind of structure can prolong the service life of road, whether it is for rigid road or flexible road system.

4. In the northern climate conditions, laying composite geogrid can help to reduce the impact of frost heave. If the freezing depth is very deep, the geonet can be laid in the shallow position of the subbase as capillary blocking.

In addition, it is often necessary to replace the granular subbase which is not easy to frost heave and extend down to the freezing depth. The backfill soil which is easy to frost heaving can be directly filled on the composite geogrid to the ground surface line.

In this case, the system of composite geogrid can be connected to the drainage outlet to keep the groundwater level at or below this depth. In this way, the development of ice crystals can be potentially limited, and there is no need to restrict the traffic load when the ice melts in the cold area in spring.
