At NK Asphalt, we employ a talented team of 25 people with two generations across four families, in both our operational crews and admin staff. Several team members have worked with us for over twenty years and have passed their skills and passion in the industry on to their younger family members.


The Owners

Trevor Calnon and Les Hackett have worked together since 1980 and since 1989 have proudly grown NK Asphalt from a small independent asphalt laying company into what is accepted by even our opposition, as one of the best in the industry.

Trevor is a full-time hands-on director and Les retired in 2012 but still has a vital and active role behind the scenes.

As well as overseeing the general running of NK Asphalt, Trevor is responsible for the overall running of the business and the quoting of work and has helped ensure the company is here for the long term so that we’ll be here if you need us again in the future.

Trevor is available to visit site for advice, quotations and to provide information that only comes from experience and many years in the asphalt industry.

Les worked in all facets of the crew and equipment and has always known the best way to tackle any problem that arises with a minimum of fuss. This role has now been taken over by our Crew Supervisor, Brad Lemmey.

Support Staff

In addition to Les and Trevor, the company’s operations are run by Trevor’s son, Paul Calnon (Operations Manager) and Les Hackett’s nephew, Brad Lemmey, (Asphalt Supervisor).

Paul has worked in all aspects of the business for nearly 20 years and now quotes work as well as administering the various works NK Asphalt provides, such as baseworks, kerbing, drainage and all aspects of site/job preparation. Brad has worked his way up through every aspect of the asphalt crew at NK Asphalt and other asphalt companies.

Paul and Brad offer a dedication and enthusiasm that will ensure the best aspects of the company are carried well into the future for the benefit of both our staff and our customers.


Our biggest advantage to you, the customer, is that the people on site, in the office, and the directors still have that old-fashioned pride in our work. Our crew are full-time wages staff and we have worked together, in some cases, for over thirty years. To ensure continuity, productivity and the best way of carrying out the job on site, we also employ younger staff. We value our staff highly and have a very low turnover. This is how we can guarantee consistency in our jobs that our opposition can only dream about.

Administration Staff

Frances Searles (Administration Manager), Margaret Kirkman (Administration Manager of C&H Sweeping) and Paul Speering (OHS Manager) play an important role in the day to day administration and processes that keep the business running smoothly.


The basis of our reputation for reliability is maintaining all our machines and equipment in optimum condition. Servicing and maintenance is carried out by our two mechanics in our premises in Maddington. With 20 machines, eight trucks and numerous smaller pieces of equipment, regular servicing is essential.
