How Geosynthetic Materials Can Benefit Your Specialty Construction Application

How Geosynthetic Materials Can Benefit Your Specialty Construction Application

No matter what you’re building or where you’re building it, you have to think about the soil on your construction site. You may need to protect it from erosion, increase its stability, protect it from chemicals, or control how water flows through it. For each of these concerns, geosynthetic materials like geosynthetic liners or geocells can provide immense benefits.

If you’re building new fuel storage tanks or putting in a municipal septic system, you’ll need geosynthetic materials. But what are they and what do they do? Read on for a brief synthesis of geosynthetic materials and their applications and benefits.

What are geosynthetic materials?

Geosynthetic materials are man-made materials that are used to protect or improve soil quality. There are several key categories of geosynthetics:

  • Geotextiles
  • Geocells
  • Geogrids
  • Geomembranes

Geotextiles

Geotextiles are fabric-like (hence “textiles”) and are felted or woven synthetic materials. These textiles often come on rolls and are similar in look and feel to landscape fabric. This geosynthetic cloth is used for its permeability and filtration characteristics, as well as its flexibility and tensile strength.

Geocells

Geocells are webs of cells formed from synthetics molded into an accordion-like structure, expanding when unfurled. These cells can be filled with filtration or fill materials like gravel or soil when the cellular confinement system (the overarching term for geocells and similar systems) is spread on a landscape.

Geogrids

Geogrids are geosynthetics that are formed into flat, intersecting grids—they look like temporary construction fencing. The open spaces in geogrids (called apertures) vary in size, depending on the desired stiffness of the material, and this design helps distribute loads over wider areas, increasing soil stability. Geogrids can be created via extrusion, weaving, or welding and extrusion.

Geomembranes

Geomembranes are the least permeable of the geosynthetic materials we’ve covered, as they’re generally used to control the movement of fluids. They are made of polymer sheets or from geotextiles treated with polymer spray.

What are geosynthetic materials used for?

At a high level, geosynthetic materials are used to protect soil. This includes reinforcing soil, preventing soil movement or loss, improving load distribution on level or sloped soil, separating soils, controlling water flow through soil, and containing liquids or preventing fluids from permeating soil. This means that when we get into specifics, geosynthetic materials and geosynthetic liners have hundreds of specialized applications for a variety of industries.

Geosynthetic material applications in the construction industry

One of the main uses of geosynthetic materials is for secondary containment. Secondary containment systems are used in conjunction with primary containment systems (that is, containers or tanks) to prevent discharge from escaping into an uncontained area. Essentially, it’s a backup containment system in case the main system you’re using to contain a material leaks or fails.

Secondary containment applications for geosynthetics include:

  • Aboveground storage tanks and foundation ringwall liners
  • Secondary containment levees, berms, and dikes
  • Spill containment berms
  • Leach fields

Geosynthetic liners can also be used for primary containment and storage, particularly for water. Some use cases include:

  • Pond liners
  • Brine ponds
  • Stormwater ponds
  • Temporary storage pits
  • Fuel reserve pits
  • Landfill Liners

It is also the case that some sort of containment is needed for situations where hazardous or potentially hazardous materials are being used or stored as a spill pad, kind of like putting down a tarp before you paint something. Potential uses in this category include:

  • Concrete protection
  • Drilling pad liners
  • Remediation pads
  • Frac tanks
  • Decontamination liners

Additionally, in some applications, like erosion control or environmental restoration, geosynthetic materials like mats and tubes may be used in combination with biodegradable materials, such as blankets made from coconut, straw, jute, or other natural fibers. This is generally to prevent soil erosion and to protect germinating plant life from stormwater runoff, wind, and animals.

Industries

Geosynthetic materials and systems are used in many industries requiring specialty construction. Here are just some of the industries that commonly require the use of geosynthetic materials and liners:

  • Agriculture
  • Fertilizer
  • Landfill
  • Wastewater treatment
  • Petrochemical
  • Chemical
  • Construction
  • Industrial construction
  • Manufacturing
  • Infrastructure
  • Water resources management
  • Environmental services
  • Power and energy
  • Industrial waste management
  • Mining
  • Industrial wastewater management

What are the benefits of using geosynthetic materials?

Each type of geosynthetic material has its own specific uses and, therefore, its own performance characteristics and benefits. But generally speaking, the benefits of geosynthetic materials are their tensile strength, durability, and permeability or impermeability, depending on the use. For containment or water flow control, impermeability is essential; for erosion control or soil stabilization, permeability is necessary to allow for natural soil behavior and health, as well as to avoid creating unintended water flow or runoff issues.

Geogrids and geotextiles are excellent for soil reinforcement and stabilization because of their resistance to environmental and construction damage, as well as their high tensile modulus and strength. Geomembranes are also resistant to damage, particularly chemical and hazardous material damage, which, paired with their impermeability, make them ideal for primary and secondary containment applications.

5 Common Geosynthetic Clay Liner Applications

5 Common Geosynthetic Clay Liner Applications

If your facility is at risk for experiencing a spill or leak, you need a comprehensive and durable containment solution to mitigate hazardous environmental exposure. And if your facility has already experienced a spill or leak, you need a solution fast.

When it comes to containment and waste management, US FUSION is your expert in rapid response and problem solving. We make sufficient repairs, we prevent future disasters, and we commonly do it using geosynthetic clay liners.

Below, we’ll walk through what geosynthetic clay liners are, as well as a few common applications for geosynthetic clay liners.

What Are Geosynthetic Clay Liners?

Geosynthetic clay liner systems are hydraulic barriers manufactured with a variety of low-impermeability materials and supporting geotextiles and geomembranes. All of these materials are adhered with chemical adhesives and mechanical processes like extrusion.

Geosynthetic clay liners are primarily used for waste management and containment. There are a number of environmental laws set by regulating agencies that require any potentially harmful seepage to be contained and disposed of properly — otherwise, these hazardous materials could cause major environmental and health issues. Although there are many containment methods available, geosynthetic clay liners provide great benefits in terms of fast installation, durability, and cost-effectiveness.

5 Geosynthetic Clay Liner Applications

Geosynthetic clay liner systems can benefit a number of containment applications. In this article, we’ll walk through just five of the most common:

1. Geosynthetic Clay Liners for Landfills

Landfills are specifically built to contain and manage waste in a responsible, effective manner. When they’re managed improperly, they can be one of the biggest contributing factors to environmental damage.

Landfills need a containment solution to prevent solid and liquid garbage waste from seeping into the soil and contaminating the surrounding groundwater and environment. That solution often involves geosynthetic clay liners, which are proven to ensure protected, safe conditions for years to come.

2. API Tanks & Foundation Liners

API stands for the American Petroleum Institute, which is an industry authority on all things oil. They’ve established standards for the design and fabrication of steel storage tanks that store oil, gasoline, and chemicals. One such API standard is the requirement that API tanks be lined with a low-permeability solution at the bottom to prevent damage from leaks or spills. There are also some API tank applications that require another layer of lining on the foundation where the tank is set, providing maximum environmental protection.

3. Geosynthetic Clay Liners for Ponds

Geosynthetic clay liners aren’t just great for managing harmful materials — they’re also great for containing something as pure as water in a designated area. One instance where this is helpful is lining a pond.

While some ponds have natural clay bottoms that provide enough of a barrier, some require an artificial or custom-fabricated solution. Installing a geosynthetic clay liner, then adding the proper soil cover, is a great option for keeping necessary water in the pond, while also blocking sediment and other debris from entering it — preserving its natural, ecological beauty and all that resides within it.

4. Earthen Spill Containment Berms

Earthen spill containment berms are containment areas with earthen walls that can vary in size They’re built to prevent hazardous materials from spilling and contaminating the environment, and they’re most commonly placed underneath high-risk devices like oil drums and tanks.

Geosynthetic clay liners can provide spill containment berms with an extra layer of protection. When placed on the surface of the berm, they’re covered with the proper soil cover, and then they can contain any spills and prevent rough terrain like rocks or sticks from poking through and causing contamination.

5. Secondary Containment Dikes, Berms & Levees

Secondary containment is an essential safeguard in stopping the release of spills. In the event that your primary containment system fails, having a backup can save you and the environment from a lot of costly damage. The versatility and durability of geosynthetic clay liner systems make them the ultimate backup for complete compliance and safety.
