Te Ngahere are experienced in the installation of a variety of walking track types. Constructing a well-formed track involves carrying out each of the following tasks:

Benching

The correct benching of a walking track is a key requirement for long-term track resilience. Te Ngahere's benching service involves:

  •  the analysis of track routes prior to commencing construction within sensitive or significant sites
     is consideredto be essential, click here for Route-finding and Mapping information
  •  the use of a "mini digger" to cut into slopes (where necessary), or to
     add soil to depressions along a track route
  •  a minimal environmental foot-print, due to the width of the digger being less than the specified track widths
     i.e it doesn't damage track edging, rubber tracks and a low profile also soften the machines impact
     on the environment
  •  flexibility with regard to be able to accommodate changes that occur in track design
     and layout as the project progresses

Watertables

The identification of issues associated with watertable management, channelling and drainage are important considerations in regard to preventing washouts and scouring.

"Water tables" are installed with a 100mm deep x 200mm wide drainage channel dug on the uphill side of the track, with a culvert (usually 150mm diameter) directing the water under the track and into natural soakages or depressions.

To reduce the amount of run-off via the drainage channel a silt-trap is dug into the channel/ watertable at the entrance to all culverts.






Metalling

Te Ngahere's metalling service includes:

  •  the use of a well-graded, specially sourced aggregate, laid over a GAP 40 basecourse,
     due to the firmness to which it compacts.
  •  the transportation (as required) of all metal via a Honda power-carrier which carries up to
     0.2 m³ of metal, which is loaded directly off the back of a tipper truck.
  •  avoiding the stockpiling of more than 4 m³ of metal at a reserve entrance.
  •  the use of a plate compactor to achieve a uniform surface free from loose chip.
