Enviroflo is an independent drainage and site works specialist based in Christchurch, founded in 2018 by Hayden Greig and Ryan Gebbie. The company has grown into one of Christchurch's leading drainage businesses, with a crew of over 30 and thousands of customers served across Canterbury.
Enviroflo covers the full spectrum of drainage work, from day-to-day unblocking and CCTV inspections through to full site works and Natural Hazards Commission (formerly EQC) earthquake repair claims, using CCTV, jetting and trenchless technology. All drainlayers are certified by the Plumbers, Gasfitters and Drainlayers Board, and the company runs an in-house claims and reporting team with extensive earthquake-repair experience.
The company is rated 4.5/5 on Google across 40 reviews, with customers regularly highlighting clear communication, tidy work sites, and a team that finishes projects — including reinstating driveways, concrete and landscaping — rather than stopping once the pipework is done. Enviroflo services Christchurch and surrounding areas including Rolleston, Prebbleton, Darfield, Rangiora, Kaiapoi, Lyttelton, Banks Peninsula, and North and South Canterbury.
Enviroflo has grown from a 2018 startup into one of Christchurch's leading drainage companies, founded by Hayden Greig and Ryan Gebbie, both experienced in drainage, civil works and earthquake repairs. Today the business runs a crew of over 30 and has served thousands of customers across Canterbury.
Rather than specialising narrowly, Enviroflo positions itself as a single team capable of handling everything from a routine blocked drain through to full site works and earthquake repairs. The company's toolkit includes CCTV camera surveys, high-pressure jetting, and trenchless repair technology, letting the team diagnose and fix drainage issues with minimal disruption to a property.
A significant part of Enviroflo's work centres on the Natural Hazards Commission (formerly EQC) repair scheme, related to ceramic drain damage from the 2010/2011 Canterbury earthquakes. The company runs an in-house claims and reporting team, assessing, reporting and managing NHC claims end to end — from an initial CCTV inspection through to submitting the claim and, if approved, carrying out the repair work. Enviroflo notes that the NHC repair window is closing, meaning homeowners with ceramic drains and a prior EQC/NHC claim may need to act before the scheme winds down to access fully-funded repairs. The free camera check applies specifically to homes with ceramic or clay drains; for PVC drains, the team can still assess the situation and discuss other options.
Enviroflo describes its process in four steps: a free camera check with a clear, no-obligation report; scoping and submitting the Natural Hazards Commission claim if the damage is earthquake-related; carrying out the trenchless or dug repair work with a certified crew; and finishing the job by reinstating driveways, concrete and landscaping. That last step — full site finishing — is something the company highlights as a differentiator, noting it doesn't stop at the pipes.
Beyond earthquake claims, Enviroflo's services span CCTV drain inspections, drain unblocking and cleaning via high-pressure jetting, general repairs and maintenance, residential drainage for renovations and new builds, commercial drainage for builders, developers and property managers, and rural drainage for lifestyle blocks and farms, including root removal.
Enviroflo holds a 4.5/5 rating on Google across 40 reviews. Customers frequently mention team member Shea by name for clear communication and supervision during earthquake repair jobs, and several reviews highlight the quality of the finishing work — driveways and landscaping left looking better than before, with one customer noting their neighbours commented on how good the results looked. Reviewers consistently describe the crew as polite, tidy and easy to have on the property.
Based in Christchurch, Enviroflo services the wider Canterbury region, including Rolleston, Prebbleton, Darfield, Rangiora, Kaiapoi, Lyttelton, Banks Peninsula, and North and South Canterbury more broadly.
Enviroflo offers a free, no-obligation camera check and free quotes, bookable by phone or through their website. All drainlayers are certified by the Plumbers, Gasfitters and Drainlayers Board, and the company applies eco-conscious practices where possible across its work.
