Construction of Landfill Using Geotextile Geosynthetics

Introduction of Landfill construction by using geosynthetics:

If there is something that continues to increase worldwide, it is the production of waste, so it is increasingly necessary to create landfills that comply with current regulations. These sites, as long as they are within the legal frameworks, serve to deposit all types of garbage safely and without harming the environment.

To avoid that this waste can cause problems and put the environment at risk, it is necessary to follow a series of guidelines in its construction. Geotextiles play a very important role in landfills and this time we want to explain their use in the landfill construction.


A landfill that does not comply with the regulations when it is built can lead to serious environmental and health problems. Therefore, in order to be considered controlled deposits, some waterproofing workby using HDPE Geomembrane must be carried out.

The following picture shows the geosynthetics used in landfill construction.

The main problem of a landfill that is not perfectly isolated is that liquids from the decomposition of waste (leachate) can seep through the surface and reach the water tanks and contaminate it.

On the other hand, when organic matter is fermented, it produces a chemical reaction that results in the creation of methane gas. This gas is a harmful substance and one of the main causes of greenhouse effect.

Geotextile membrane is a material used in the landfill construction solution for the waterproofing of landfills as a function of protecting the geomembrane, in addition it is also used as a barrier for the separation of aggregates, normally draining gravels.

Special attention must be paid to the composition of the geotextile, always using high tenacity geotextiles and 100% virgin polypropylene, which are totally inert to the leaching action and that offer optimum resistant properties, thus ensuring that the Geomembrane protection is effective and the risk of leaks will be avoided.

Layers according to the type of waste that is deposited in the landfill:

How to isolate landfills with a geotextile:

The top landfill layer is what is done when you want to seal a landfill. By means of nonwoven geotextile, it is possible to cover it safely and protect it from rain and other agents that may infiltrate. The barrier that is built is called waterproof and is completely waterproof. Thus, with different geotextile and geomembrane materials, the complete tightness of the landfill is achieved.

In GTM Geotextile we are experts in the manufacture and marketing of geotextiles and geomembranes for the construction of landfills, if you need to receive more information about this type of materials you can do so through our contact form.

Application of geosynthetics in solid waste management is very important.
