Liquid Containment Liners
The purpose of these liners is to protect the earth and water sources from oil, gas, or hazardous chemicals from drilling and other construction. These liners need to be chemically resistant, high impact and tear resistant in order to perform well protect the environment from contamination.
Types Of Liners
There is a long list of different types of liners but generally speaking there are two main materials that help categorize them. High-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE). HDPE gives the liners great durability and chemical resistance. LLDPE gives the liners a great amount of stretch while maintaining excellent tear resistance.
You can get these liners smooth or textured on one or both sides. With a range of thicknesses and colors, including white, green and black. The textured liners increase the amount of friction between the liner and the soil which allows for steeper applications. Generally these liners come in one large section and can be up to 8,000 pounds! They are folded accordion style and rolled onto a large core. This makes the liners easier to transport and install.
Why Liners Are Better Than Concrete
Different types of liners are used for different applications so no matter what type of work you are doing GeoTK will have a liner for you. The liners are made with reinforced polyethylene like HDPE and are excellent for water containment. It’s very cost effective and provides great durability. In a lot of applications these liners are used as a secondary containment option. The first, common choice being concrete. And while concrete is strong, durable and resistant to most elements, it does have a higher chance of leaking through small gaps or cracks. That is why using geomembranes as a primary or secondary containment method is a better idea.
These liners not only last up to 30 years but they won’t develop leaks or damage like concrete will. There is a considerable cost difference between the two as well. Concrete can be upwards of double the cost of liners per square foot. When building a containment area consideration of the subgrade is important when working with concrete. Because concrete is not immune to high levels of chemicals and can have adverse reactions when the soil is high in sulfates or when working with waste or seawater, the use of liners can be a better option. Most liners are coated with a chemically resistant barrier, so there is not need for extra expenses or designs. When the subgrade you’re working on is soft, it can be hard to build a heavy concrete structure on soft and uneven ground. But liquid containment liners have no problem with uneven terrain. They are able to flex and stretch to fit however you need them to.
All in all, liquid containment liners are a better choice for primary and secondary containment. They are quicker to install, less expensive, require less subgrade design and are more environmentally stable than concrete.
