The landfill capping system is a controlling process that forms a barrier between the unwanted hazardous waste and the environment. A capping system is necessary to shield the waste materials from harming the surrounding environment and human health. A good quality closure system must prevent the contaminated materials from entering the surface water in order to prevent pollution.

We all know that human beings are increasing their garbage level currently, and all that waste material goes to the nearby landfills. Like most other things, every landfill has its limitation. These landfills are full with hazardous and unsafe materials that can damage the surrounding environment. After the upper limit of a landfill is reached, it can no longer hold waste and should be closed for use.

For covering up a landfill, several types of capping systems can be used. Some can be used for hazardous grounds, and some for non-hazardous ground. Commonly, compacted clay is used as cap; however, if the moisture level is below a certain point, there is a chance of cracking if the material dries out a lot. Moreover, a cracked capping system is not good for covering up a waste disposal ground. Many health hazardous materials can enter the level of surface water and ground water through this crack. HDPE and LLDPE caps can also be used, but are prone to wrinkles, cracking, gas hippos, waves and other damages. Traditional soil cover capping systems can be costly, consume high volumes of natural resources, require labor intensive installation and can be prone to erosion.

Due to this disadvantage of the traditional capping system, there are now some artificial capping systems available. This LiteEarth capping system applies synthetic grass or artificial turf for capping a landfill. The artificial grass is permanently combined to an EPDM geomembrane to create an impermeable and safe earth capping system.  LiteEarth is cost effective, efficient and requires fewer resources to install than a traditional capping system.
