3. Water permeability: The grid-like structure makes the geogrid have good water permeability, which is beneficial to soil drainage and ventilation, and prevents water and mud accumulation.

The advantages of geogrid water permeability in civil engineering are mainly reflected in the following aspects:

(1) Promote water penetration: The special structural design and material characteristics of geogrid make it have good water permeability. The void structure of the grid can promote the penetration of water, allowing water to quickly pass through the grid without being retained on the surface, thus reducing the risk of soil erosion.

(2) Maintain soil permeability: The water permeability of geogrid is not only reflected in the penetration of liquid water, but also includes the permeability of gas. By promoting water drainage and soil aeration, grids help maintain soil permeability and improve soil aeration levels, which is beneficial to plant growth and root development.

(3) Reduce surface water accumulation: During rainfall and other conditions, geogrids can quickly penetrate water into the ground and reduce the accumulation and retention of surface water. This helps prevent surface erosion and soil loss caused by pools and standing water while reducing surface water stress.

(4) Improve soil drainage conditions: By installing geogrids, soil drainage conditions can be effectively improved. The grid promotes the penetration and drainage of water, reduces water accumulation and waterlogging in the soil, improves the drainage performance of the soil, and is conducive to soil maintenance and improvement.

(5) Increase soil moisture reserves: Although geogrid helps with drainage, its permeability also means that it can penetrate water deep into the soil, increasing the soil's moisture reserves. This is especially important in arid areas or during dry seasons, helping to keep the soil moist and plants growing.

Therefore, the water permeability advantage of geogrids in civil engineering can effectively promote water penetration and drainage, improve soil ventilation and drainage conditions, reduce surface water accumulation and surface erosion, and increase soil moisture reserves, providing a feasible solution for the project.
