Some recent flooding issues Drainage NZ has resolved

A drainage solution is not just finding someone that can dig a hole and throw a punched Nova coil into the ground. There needs to be an understanding of physics and a plan needs to be engineered which is closely linked to the issues you are facing.

Subsoil Drainage Solutions

Drainage NZ have been involved in 100s of subsoil drainage solutions around the larger Auckland area. We have done everything from engineering soak holes to providing unique thrusted and/or drilled solutions for home and business owners that assumed no solution existed.

In Auckland you will find several extreme ground conditions. Whilst in Mt Wellington you may have volcanic ground, in West Auckland or on the North Shore you will find many areas are meters deep in clay that offers zero ground percolation. Where the one offers plenty of soakage the other will offer none but both have one thing in common requiring an engineered methodology to tackle the different forms of flooding that are affecting properties.

Our solutions also include many properties that are affected by no available public storm water networks requiring self-management of roof and surface water.

Consents and Plans

If and when design and consent are (e.g in some instances pumped solutions) required Drainage NZ take care of everything. We have designers in-house that work closely with our field technicians to achieve your desired scope successfully.
