Geomembrane Tankliners for Cylindrical Concrete Tanks
Your ‘standard’ 20,000L - 30,000L concrete, timber, plastic or fibreglass tank can be lined and back in service in 4-6 hours for a fraction of the cost of replacement.
Custom made to each tank, we replace fittings, valves and pipework to renew the life of your tank and return it to full function.
We’ve installed Tankliners to everything from 100 litres to 1,000,000 litres. -
Geomembrane Tankliners for Cuboid & Subfloor Concrete Tanks
Custom Geomembrane Tankliners supplied and fitted to any size or shape of in-ground or cuboid tank.
Dwellings on prime sites often maximise site area by placing a tank under the house or garage, we’ve lined hundreds of these tanks and have developed our own techniques for many odd ball jobs whether retrofit or new build.
L shaped tank? Can do.
Partition wall inside of tank? Can do.
No external access to pipework? Can do. -
Plastic Tank Repairs
With a full kit of plastic welding tools on hand we can repair your split plastic tank with either patch repairs or a Tankliner.
Extrusion welded plastic tank repairs are usually the best option for plastic tanks as it will stop the crack or split from migrating further while supporting the split area by adding material to the area with a true molecular bond to the base material of the tank.
All of our plastic tank repairs are undertaken from the inside of the tank, we’ve got a 100% hit rate on these repairs, a number of which other contractors had attempted from the outside of the the tank without success. -
Primary & Secondary Containment
Custom LDPE/HDPE containment solutions for preservation containers, hazardous material storage and everything else.
We have testing reports along with chemical resistance charts available for all of the geomembranes we use and take great care to match the product to the environment and potential contact chemicals.
We have weld testing equipment on hand to verify the container is impermeable.

Geomembrane Tankliners are a cost effective, quick, reliable and safe solution for leaking tanks.
Tankliners are a cost effective solution over replacing your tank and offer the same life expectancy (30 plus years).
Installed in one day, we can have water back in the tank as soon as the Tankliner is installed. No lengthy downtime and no need to factor in alternative supply costs for your family or tenants.
