The Trench is here!

We are here to service your industry.

What is The Trench?. The short answer is that we are a New Zealand owned and operated company, designed specifically for the Civil and Infrastructure industry. Three industry savvy people saw the need for a central meeting point for New Zealand contractors and councils, where they can source relevant and up to date product information, swap ideas, and buy or sell excess materials left over from projects. Our industry is able to support a good level of sustainability, through the "recycling" of unused materials and plant, that is sitting in yards across the country right now. Up until the arrival of The Trench, there has been no effective way to do this, and this is where The Trench will show what it can do. Whilst we build up the databases and technical information resources, the Trading section will be fully functional, meaning you can buy or sell and read up on our product reviews.

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 SN4 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 pipe.

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 prefeered 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 9 years I have worked in the 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, beginning this calendar year. The incumbent line, a concrete 900mm line, suffered quite bad damage a couple of years back when a a freak storm, pushing one of the strongest easterly winds seen in the region, pushed over trees like they were toothpicks, and threw them down the hill side, putting large holes in the pipe line. A very interesting point to note here, is that the pipe line travels kilometres above ground, and despite what you may have been told about hairline cracks in concrete pipe, I can tell you that the section of pipe line I have ridden past several hundred times in the last 5 years, never leaked any more than a puddle of water. Hair line cracks do self heal, it is not a placebo being fed to you by those whom sell concrete pipe.
The new pipe is looking like it will be a concrete lined steel line, but alternatives are being considered. I attended a Q & A meeting last week, and can report that it is progressing towards the point of being awarded, with a deadline of 21 September in mind.
