NEW CONCRETE TANKS
- Tests show Butyl Rubber can last over 40 years and still remain elastic.
- Using rubber on a new building will help you achieve Green Star rating – rubber is an environmentally friendly material
- Rubber has a wide range of operating temperatures making it ideal for Fire Water Storage
- Rubber remains flexible and elastic over its lifetime. Most other materials will permanently deform when stretched
- Rubber is tougher and more puncture resistant than most other membranes.
- Liners can be made in one piece and fed into a confined space.
- Rubber liners can be fully installed in a confined space without use of chemicals or hot works. Light tooling only.
- Rubber is nominally thicker than most flexible alternatives
REFURBISH PAINT-ON CONCRETE TANKS…
…. by dropping in a butyl rubber liner
Why paint-on waterproofing in tanks fail
- Paint-on waterproofing methods are subject to failure due to movement in the building. Concrete cracks and so will the coating.
- Groundwater behind a paint-on waterproofing system will lift the coating and ‘bubble’ it off, compromising the waterproofing
- Paint-ons are subject to the skill of the applicator
The solution is dropping in a rubber liner. Rubber tank membranes can be made to measure, supplied in one piece and safely rolled out and retrofitted in the confined space of an existing tank.
Butyl is an ideal material for lining water storage tanks. Durable and tough, the material can be delivered to site without damage. Larger liners can be manufactured in sections and site vulcanized to ease installation. Butyl is the only material approved by FM Global for use in appropriately insured fire tanks.

BOLTED STEEL WATER TANKS
Bolted steel tank industry is Southland’s traditional market for water storage membranes. The portable nature of the liners perfectly compliment prefabricated bolted steel tanks. The tank shell can be constructed quickly to structurally withstand the hydrostatic loads, leaving the job of containing the liquid contents to the one-piece membrane.
Eyelets
Eyelets can be installed along the top edge of the tank liner wall – a Southland Liners innovation which is now industry standard for tank liners, regardless of the material used. The liner is secured to the top edge of the tank via bolts. The eyelets help to distribute the the point loads at the hanging points to reduce risk of tear out.
Packaging
Tank liners are folded and rolled to ensure ease of manipulation on site. Butyl is resilient to fold cracks and tough to resist abrasive damage from sharp folds. It will not become brittle over time in storage.
Unfolding instructions can be provided on dispatch. Alternatively, if a specific layout is required, Southland can package the liner to suit. All folding is done by hand and the liner is wrapped in geofabric prior to dispatch to avoid damage during transportation to site. Larger liners can be supplied with special lifting provisions if lifting equipment is available on site. Liner size/weight charts are available on request
