The Trench: New Zealand's Infrastructure Network

What is The Trench?.

The Trench is very simple, we are money in your back pocket. There has been a need for years, for a way to liquidate excess project materials and plant, by Contractors, Councils, Merchants, and anyone with industry specific products they no longer need. The creators of The Trench are all in the industry, and carry a collective 50 plus years of experience in it, which means what you see and read on this website, will be in a language you know, and will show products you are very familiar with. This is not a place to buy and sell used furniture, or clothes dryers, it is just for our industry, meaning you can give your staff full access to it, knowing they won't be sneaking a peak at the footwear section, because we don't have one of those.

Our industry is able to support a good level of sustainability, through the "recycling" of unused materials and plant that are sitting in yards across the country right now. Up until the arrival of The Trench, there has been no effective way to do this.

The Pipe Line

The Boss is in!

By now, you will have at least seen or heard of Boss Pipe. Boss is a complete range of polypropylene twin-walled pipe, utilising an extremely strong corrugated exterior, with a traditional smooth bore, that is colour coded. There is a black lined pipe for the basic Farm grade, which surprisingly enough, is still a minimum of SN6 rating, then you move to a grey lined pipe, which is an SN8 or SN16 Stormwater grade, then you move up to the terracotta colour lined pipe, which is SN16 rated Sewer grade

Boss has a full range of Junctions, manhole starters, bends and various joining options, and is already specified by a number of New Zeland City Councils as the preferred pipe for their sewer and stormwater installations. Because Boss is made from Polypropylene, it is also significantly lighter than it's PVC counterparts, while able to match and usually better the PVC's stiffness rating, while dramatically reducing OSH hazards, by being light enough that one man can lift a piece of 375mm Boss pipe without struggling.... try doing that with PVC

Boss Pipe also has the ability to flex, without shattering or cracking, which in New Zealand now, is something to be considered strongly when installing new pipelines. In the 10 years I have worked in this industry, Boss Pipe represents the most significant advancement in Storm and Waste Water piping. It is available currently in 225mm, 300mm, 375mm and 450mm. The Manufacturer is based in New Zealand, and is 100% NZ Owned and operated. Click here to visit the manufacturers Website.

Featured Project

Nelsons new Pipe-line

The Nelson City water supply pipe line from the Maitai Dam, to the water treatment plant, just off Brook St. Nelson, is being renewed, and is currently nearing the end of the second stage. The incumbent line, is a 900mm concrete one, and was layed in the 1950's, with huge sections of it laid above ground. A fews years ago, Nelson had a major weather event, with very strong easterly winds, and heavy rain fall, which snapped mature pine trees off like twigs, and slid them down the mountainside, knocking large holes in the old concrete pipe line. The new pipe is 600mm CLS, and follows a completely new route. Fulton Hogan Nelson have been responsible for the first two stages, and are showing their expertise in tackling large scale projects, dealing with obstacles like ripping through roads that are solid rock, and installing 2.5 tonne valves on steep hillsides. The access road that the first two stages are running along, is narrow, and often only one lane wide , but disruptions to the local residents, and the huge mountain biking population have been managed very well.
