Quality Assurance

Quality installation and liner selection are essential for successful containment and adherence to dairy effluent standards.

A minor breach can have toxic effects and considerable financial costs, for this reason you need to have 100% confidence in your pond lining specialists. 

At Enviroline NZ we achieve this through a blend of exceptional workmanship, sound technical expertise, the right tools to do the job, superior HDPE liners and thorough testing throughout liner installation.
