Water Tank Liners

Expertly prefabricated in our factory or fully cut and installed on site, we recommend and use what is known as the best water tank liners and materials on the market. Discover quality PVC tank liners that offer high tear resistance as well as Butyl and EPDM tank liners.

Water Tank Liners

Climate change and the constantly growing demand for water are causing the pressure on existing resources to increase drastically. Here at Stephens Industries, we offer water storage tank liners to reduce this burden and offer a suitable alternative – in time, increasing the self-sufficiency of water. Being in the industry for a number of years, our team has completed several projects concerning the fabrication, distribution and installation of many EPDM tank liners throughout the UK.

With 65 years of experience in liquid containment and successful installation of tanks and lagoons UK-wide, contact us today to discuss your water tank liner requirements in further detail, or to learn more about our choice of preferred materials we readily supply including EPDM tank liners and PVC tank liners.

Water Tank Liner Materials

0.75mm & 1.00mm Elastoseal EPDM Tank Liner

The standard specification for our EPDM tank liners, this material has a variety of benefits that make it the material of choice of many of our customers. EPDM tank liners are highly flexible, so can adapt to various tank shapes and sizes. Rubber pond liners are also relatively easy to install and require minimal maintenance.

  • Designed for above ground steel water tanks
  • Synthetic rubber
  • Ideal replacement for aged Butyl liners
  • Excellent UV resistance, 40-year service life
  • Factory prefabricated for tanks up to 30m diameter, 10m high

1.00mm WRC Butyl

Where a tank is used for the storage of drinking water, we can fabricate the tank linings from WRC Approved Butyl.

Some great properties of 1.00mm WRC Butyl liner include:

  • WRC approved material
  • Synthetic rubber
  • Used for the storage of drinking water
  • Passes BS6920 for Appearance of Water, Growth of Microbes, and Odour/ Flavour
  • Excellent UV resistance

0.75mm Butyl Liner

We are also able to fabricate tank linings constructed of 0.75mm Butyl.

Butyl is the traditional material of choice for applications such as tank liners and is still widely used today in sprinkler tanks.

Although the use of a Butyl liner is often more costly than its 0.75mm EPDM alternative, Butyl has the added benefit of less shrinkage over its lifetime.

900gsm Reinforced PVC Tank Liners

In applications where a high level of tear resistance and tensile strength is required, our 900gsm reinforced PVC is an ideal material.

  • High tear resistance
  • High tensile strength
  • A life expectancy of circa 10 years when exposed to UV degradation (significantly greater if covered)
  • A cost-effective alternative to 1.0mm EPDM
  • Available in a variety of colours

AquaSHIELD Protective Matting

To protect your liner from being damaged by the tank, we always recommend the use of our high-quality protective matting.

The grade of protective matting, either 200gsm or 275gsm, will depend on the size of the tank, and its condition.

All of our aquaSHIELD protective underlay is:

  • Made of superior quality, non-woven polypropylene Geotextile
  • Compatible with all tank lining materials
  • Rot, UV, and weather resistant

Liner Construction

At Stephens Industries we fabricate our water tank liners in our factory. This means we have complete control over the manufacturing process and can ensure that the liner is made exactly to our customer’s requirements.

Our tank liners are constructed using a variety of techniques depending on how the liner will be installed, and the design of the tank itself.

Where possible we aim to produce a tank liner as a single piece, prefabricated to your specified size, which can be fitted to the tank as quickly and efficiently as possible.

In some circumstances, i.e. where the tank is of a complex design, the liner can be supplied in multiple parts to be joined on-site. In this case, the liner walls are often supplied as one piece, with the liner base being provided as a second piece.

Component Integration

Our customers frequently require bespoke elements in their tank liners. We are always happy to accommodate our customers’ requirements where possible and can incorporate such specialist elements either during manufacture in our factory or on-site.

Securing Water Tank Liners

The method used for securing the liner to your tank will often depend on the size and design of your water tank.

Securing using integrated eyelets

  • The most secure and durable method of fastening.
  • Requires mechanical fastening to the tank wall.
  • Used in medium to large tanks.
  • Eyelets are evenly distributed around the circumference of the liner to ensure even weight distribution.

Securing using capping

  • Uses a two-part system to secure the liner under pressure along the top edge of the tank.
  • Used in small to medium-sized tanks.
  • No mechanical tank fixings required.
  • Can be used in conjunction with a ratchet strap for added support.

Securing using a ratchet strap

  • Uses a single ratchet strap to secure the liner on the exterior of the tank wall.
  • Economical solution
  • Used only in small to medium tanks.
  • No mechanical tank fixings required.
