Introducing Manhole Form Hire’s patented “super bolt”

Anyone in the formwork or concreting industries, including anyone that ever used a bolt in the assembly or disassembly of temporary construction structure, knows the intense struggle of releasing a bolt from a structure after it has been used and its threads are filled with layers of dirt, crud, dried concrete and aggregate. 


When assembling or disassembling a large structure such as a concrete form or manhole form, clogged and stuck bolts can add additional minutes to a project's length. And when you are working with forms that have between 30 to 80 bolts per form, if every bolt is difficult to remove it can result in hours of lost productive time on a project.

The Manhole Form Hire solution: super bolts!

No one knows the struggle with using traditional bolts better than our manager, Barry Kuster. He struggled with this exact issue on every job when assembling and disassembling the manhole forms. To help combat all the time wasted unsticking clogged bolts, Barry took matters into his own hands and developed a bolt perfect for his business and indeed anyone working with concrete in the construction industry.

How do super bolts work?

This bolt has a courser thread, which enables grit, sand and debris to slough off and clean itself as its being turned. This new bolt clears grit, dirt and dust as its being removed in a disassembly process, allowing for the person removing the bolt to spin it through the form at a much quicker pace without it getting snagged and stuck. Having a courser thread means you don't have it turn it as many times, and debris is removed through the process of turning the bolt.


This seemingly tiny innovation, a bolt that looks very much like any other bolt, can save between 15-30 mins in putting a manhole form together, and the same again in the disassembly process.


Without manholes and access chambers, civil infrastructure workers would not be able to run maintenance checks, carry out essential updates and fix issues when they occur. Not only do manholes and access chambers play a major role in the day to day lives of civil infrastructure workers but they are crucial to the ongoing functionality of the underground utility network during a crisis.


During times of flooding, storm and tidal surges manholes provide the water trapped in the stormwater tunnels with a place to escape, rather than continue to build up and potentially cause structural damage to the tunnels. If the lights of a major road intersection go out workers are able to quickly and easily access the control panel through a manhole or access chamber and get to work fixing the issue.


Problem solving across the industry

Once the bolt became a tried and tested piece of equipment that was used daily on all manhole form construction and deconstruction processes, Barry decided that if this bolt worked so well for manhole forms, then it would ultimately work for his competitors, and other people working in the concrete structures business, or anyone working with concrete in general. 


With the goal of his invention becoming a staple piece of concreting working equipment and one day being sold at Bunnings, he began the arduous undertaking of applying for a patent, which he now owns for the bolt, being the first person to invent, and bring to market, a bolt that is perfect for people working with concrete.


Thanks to this patent, the bolt was able to be developed further, and it is now available in a range of sizes and thread widths so that the right bolt is available to fit any concrete working project. As the next step of making this bolt available to construction workers around the world, Barry intends to start manufacturing these bolts to sell to others in the formwork industry or to anyone working every day with temporary structures around concrete.
