Landfill Liner

A Landfill liner  may consist of many differing types of material but the end objective is always the same regardless of the path taken. The landfill liner is the first line of defense against water leaching into the ground water (base landfill liner) as well as rain water intruding into the landfill solid waste area.

 The landfill liner can be made from clay, synthetic flexible membranes or simply extra thick plastic sheeting. As you can see form the picture above this landfill liner consist of a synthetic membrane.  The membrane is there to keep the waste water from leaching into the ground water. This method of sealing the base of the landfill is very tedious and extremely costly.

Many landfill liners today are made of a tough plastic film called high density polyethylene (HDPE). A number of household chemicals will degrade HDPE, permeating waste water to pass through.  Not only will household chemicals degrade HDPE, but much more benign things can cause it to develop stress cracks, such as, margarine, vinegar, ethyl alcohol (booze), shoe polish, peppermint oil, to name a few. These cracks will only get larger with time allowing more waste water to escape. these problems are prevented with the SCI landfill liner program. 

The other method is to place many layers of clay in the bottom as to crate a low permeable landfill liner of clay. Yet natural clay is often fractured and cracked easily with temperature and moisture changes. A mechanism called diffusion will move organic chemicals like benzene through a three-foot thick clay landfill liner in approximately five years. Again the SCI landfill liner program will aid in preventing these problems and at a much lower cost.

Again, these methods seak the same end result, which is to decrease or stop all waste water from escaping and rain water from entering the landfill. This is accomplished by introducing or creating a low permeable layer that will stop the escaping or intrusion of liquids. SCI is able to deliver that low permeability into the soils that is there on site. This fact assures that you may eliminate or enhance the employment of a geo-textile landfill liner as well as reduce the need for trucking in millions of tons of clay.

The process of crating a SCI landfill liner is simple and much more cost effective than the alternatives. All one has to do is spray our product  onto your soil at a prescribed rate and  prescribed concentration. These rates and concentrations are determined from lab testing  your soil with varying iterations of or mixtures. Once the prescribed application has had time to soak into the soil, you will simply compact that area and allow to dry. This concludes the creation of your landfill liner.  You will now have a section of soil that will have a permeability coefficient of less than 10^-7 cm/sec. No need for plastic liners or importing expensive clay. The SCI landfill liner program is the most cost effective, time saving program available to landfills today.
