Blind ditch is a drainage ditch set up in subgrade or foundation. It should be filled with coarse-grained materials such as gravel and lay a filter layer. Blind ditch, also known as seepage ditch, is an underground drainage channel to remove groundwater and reduce the groundwater level.
Plastic blind ditch is a three-dimensional porous material. It is made of thermoplastic synthetic resin.
The melted resin is heated and extruded through a nozzle. Then, the filaments are stacked together and their contact points are dissolved together. In this way, a plastic blind ditch is made.
The filter membranes and polyethylene which make up the blind ditch have good corrosion resistance. And they all have the advantage of never degrading in soil and water. In addition, anti-aging formula is added to the material, which can ensure that the material of blind ditch will not change permanently.
Filtration membranes for plastic blind ditches can be selected according to different soil conditions. This fully meets the needs of the project.And it avoids the disadvantage of single filter membrane of old products.
The proportion of plastic blind ditch is light, and it is very convenient to install in site construction. Therefore,Construction efficiency has been greatly accelerated.
It is widely used in：
Drainage and moisture proof of underground buildings
