Prefabricated Tank Liners


Drop-In Tank Liner, Liner attached to top ring wall with Clamps Drape- In Tank Liner for Modular Steel Tanks
Tank liners are a common use for geomembranes and are a growing part of Layfield’s fabrication business. We regularly fabricate geomembrane liners to the sizes needed to line both steel and concrete tanks in a variety of sizes. A rapidly growing use for tank liners is in the lining of bolted corrugated steel tanks. Adding a prefabricated geomembrane liner to these corrugated steel tanks creates a cost effective containment for water, wastewater, and oilfield water containment applications.

We produce all types of tank liners however there are three that are the most common. First there is the drop-in type of tank liner that is made in a cylindrical shape to match the tank. Second is the drape-in type of tank liner where a flat sheet is folded into an open topped tank and secured to the top. Third are the tank liners that we actually build and fit on site (field fabricated tank liners).

Most geomembrane materials can be used for making tank liners. For flat sheet drape-in style liners with low wall heights our Enviro Liner materials are very effective. In hydraulic fracturing operations we are typically making Enviro Liner drape-in liners to fit tanks 120 ft in diameter with walls about 12 ft high (36 m by 4 m high). Our Geoflex material is very popular for drop in style water tank liners in smaller tanks 20 ft in diameter by 10 ft high (6 m diameter and 3 m high). For permanent installations with wall heights over 10 ft (3 m) high a fabric supported material is normally recommended. Fabric supported materials have high strength fabrics in their core and are resistant to long term creep on the walls and higher service temperatures.

Layfield can provide an estimate for your tank liner from your dimensioned tank drawing. We will also need to know the contents of the tank (including temperature) and the estimated service life. Then we’ll need to know how the liner attaches to the top of the tank and how many pipe penetrations are required to get liquid in and out of the tank. Call your Layfield representative today to start on an estimate for your next tank liner requirement.
