Spray-Applied Liner Systems

Spray-Applied Liner Systems

No Secondary Containment Project Is Too Complex

When complex detail work is required, spray-applied geomembrane materials are your first choice. In retrofits of existing secondary containment tank farm liner and primary tank relining, and in areas where multiple pipes need to penetrate the liner, a spray-applied material is often your best option.

Formulated to resist many complex chemicals, often at high service temperatures, spray-applied geomembranes encapsulate details with a seamless liquid barrier that dries solid. Since Layfield provides both spray-applied and sheet-type liners, we have developed proprietary methods for adhering spray-applied and sheet-type materials together to provide an effective containment system for almost any application.

What Makes Spray-Applied An Ideal Solution?

Ease Of Installation

Spray-on geomembranes can sometimes be placed while the tank farm remains in operation, as piping does not need to be disconnected.

Excellent Chemical Resistance

Provides containment for most oil and petroleum products, pesticides and herbicides, hydrocarbon solvents, sulfurs, chlorinated solvents, alkalis and acids, animal waste, and salt solutions.

An Easy Solution To A Complex Problem

Spray-applied geomembranes are ideal when complex work details, including multiple penetrations or complex geometries, are encountered.

Additional Features

  • Excellent temperature resistance
  • Conforms to surface to provide a seamless liquid barrier
  • Adheres well to both metals and concrete
  • Custom formulations available

Product Specifications

Spray-applied polyurethane and polyurea geomembrane materials can be formulated for specific jobs. The final chemical resistance can be adjusted by changing the formulation of the input chemicals that combine to make the final geomembrane. Chemical resistance can be "adjusted" for different applications when required. The standard formulations of spray-applied lining materials are highly chemical resistant; however if you are trying to contain a chemical that is not listed for that formulation a new formulation can be prepared. Spray-applied geomembranes are thermosetting polymers that cure after application. This is quite different from the thermoplastic materials used in most sheet liner materials. A thermoset plastic has extended chemical resistance and often can handle chemical containments at higher temperatures. Often a spray-applied liner will be called for when service temperatures are higher than a sheet liner can handle. Spray-applied liners can be used to contain or provide secondary containment for most oil and petroleum products, pesticides and herbicides, hydrocarbon solvents, sulfur and related compounds, chlorinated solvents, alkalis and acids, animal waste, and salt solutions.
