Geonets
Geonets are three-dimensional nets used to drain or separate soil or other materials. They are made from polymeric materials such as polyethylene or polypropylene and are available in a variety of pore sizes and strengths. Geonets are often used in drainage applications such as landfill leachate collection systems and French drains.
In a leachate collection system, for example, geonets are placed between the bottom liner and the soil to create a void space that collects leachate. The leachate is then channeled away from the waste material, preventing contamination of the surrounding environment. When used in a French drain, geonets help to increase the storage capacity of the drain by creating an additional void space for water to flow into. This can be especially helpful in areas with high rainfall or where groundwater levels are close to the surface. By helping to store and channel water, geonets can play an important role in protecting both the environment and human health.

Drainage Composites
Drainage composites are frequently used in drainage applications, as they can provide an effective way to remove water from an area without causing damage to the surrounding environment. There are a variety of different types of drainage composites available on the market, and each has its own advantages and disadvantages.
One of the most popular types of drainage composites is known as a geocomposite drainage blanket. Geocomposite drainage blankets consist of a layer of nonwoven fabric sandwiched between two layers of geotextile fabric. The nonwoven fabric helps to absorb water, while the geotextile fabric prevents soil particles from clogging the drains. Another type of drainage composite is known as a perforated drain pipe. Perforated drain pipes are made of a variety of materials, including PVC, HDPE, and polyethylene. The holes in the pipe allow water to enter, while the solid walls prevent soil particles from entering.
Perforated drain pipes are often used in conjunction with French drains or catch basins. French drains are typically installed around the perimeter of a structure, and they consist of a perforated pipe that is surrounded by gravel. Catch basins are similar to French drains, but they are typically installed in areas with a high water table.
When choosing a drainage composite for your application, it is important to consider the type of soil you have, as well as the amount of water that will be present. For example, if you have sandy soil, you may want to consider using a geocomposite drainage blanket. If you have clay soil, on the other hand, you may want to use a perforated drain pipe. No matter what type of drainage composite you choose, it is important to install it properly in order to ensure that it functions correctly.
