During the twilight years of a successful, 40-year career with Lafarge in Eastern Canada, Bob Castle pondered what he would do in order to stay busy once he retired. Prior to retiring in 2002, Bob decided to purchase a small concrete company located in Brockville, Ontario. Thousand Islands Concrete (TIC) was not just any concrete company; TIC ran 4 Daffin volumetric concrete mixers to fulfill customer orders. Lucky for Bob, the sons of the previous owner stayed on with the company so he had experienced delivery personnel capable of maintaining the old, outdated mixers.

Commercial / IndustrialEarly on Bob knew he had to replace the Daffin mixers that were breaking down regularly. He realized he needed more up-to-date, reliable equipment, especially if he wanted to go after higher volume projects. There were a number of reasons why Bob wanted to stay with volumetric mixing technology:

  1. Smaller yard investment (silo and small acreage). This would allow for versatility in the regional growth plans.
  2. TIC customers order concrete for remote locations. The easiest way to deliver fresh concrete was mix-on-site with volumetric mixers.
  3. Volumetric mixers create very little waste. When the pour is finished just turn off the mixer. All materials are held separate so they can be mixed at the next jobsite.
  4. Volumetric mixers have a smaller carbon footprint. Overall, there is a significant reduction in truck trips since there are no extra trips to the jobsite for clean-up loads.
  5. Customers recognize the value. TIC customers were well-aware that they only pay for what gets poured; if they order 5m³ and they only need 4m³, they pay for 4m³.

Commercial / IndustrialAfter extensive research, Bob chose Reimer Mixers. “ProAll has a reputation for excellent mixer products and is a great company to do business with. I couldn’t believe how much the mixers had advanced compared to our old Daffins” stated Bob. “I also wanted to do business with a Canadian company, so selecting ProAll was an easy choice.” Initially, Thousand Islands Concrete ordered one mixer to try it out – the efficiencies compared to the old equipment were amazing. Between 2002 and 2005 Bob swapped out TIC’s entire fleet of mixers to Reimers. “During our cross-over to Reimer Mixers we would use the older trucks on smaller projects and COD orders. The Reimers were used on larger projects because of their production speed and capacity.”

Commercial / Industrial2005 was a defining year for TIC. Bob’s son Steve Castle left his position at Lafarge to work in the expanding TIC business. Like his father, Steve has a legacy in the concrete industry. When Steve was 16 and continuing throughout his school years, he worked every summer in the concrete industry in Northern Ontario. Steve worked his way up from the quarry to batching, testing and driving ready-mix trucks. Once he graduated from university, he went to work for Lafarge and over his tenure ran several plants in the Ontario region. “Initially, we both were a little nervous about working together, but it has worked out completely. We both had careers in management at Lafarge (Steve 15 years, Bob 40 years); we were extremely familiar with the successful business framework that Lafarge deploys within their management team”, Steve comments. “We had the wisdom and the vision to be successful based on our large company experience”.


Commercial / IndustrialAfter Steve joined the company, Bob and Steve created a 5-year plan to grow TIC revenues and to expand regionally. Through this planning process, they recognized that there was a large, untapped market in Ontario’s cottage country. TIC could radiate out from the main plant in Brockville, setting up depots where the mixers could recharge materials during the day and return to one central location each night for maintenance.

The main thing that sets TIC apart from their competition is their equipment – they are the only operation deploying volumetric mixers in their marketplace. There are features to their business model which needed to become key messages for their customers and prospects:

  1. Only pay for what you use.
  2. No wait times for balance / clean-up loads.
  3. You don’t have to be overly specific in how much concrete you need (in some areas, because of the terrain, it makes calculating the volume of concrete required very difficult).
  4. Customers in remote areas (where there are no ready-mixed companies) can get fresh concrete because it’s made on-site.

Commercial / IndustrialTIC developed a partner program which identified contractors to approach and solidified relationships with them. Initially, in order to break the barrier to contractors ordering concrete from volumetric mixers, TIC set up one forming contractor who did 50+ foundations each year. “We let him use a mixer to get into the business and now he’s our largest customer” comments Bob. “He was sold on Reimer Mixers because he could eliminate wait times for clean-up loads and only pay for the concrete he used – these savings add up to wages for one crew member every week.” TIC collects testimonials and referrals from these partnerships that help to validate the business model; ultimately growing the business.

Commercial / IndustrialBob is a past president of the Ready Mixed Concrete Association of Ontario and recognized the importance of TIC being an association member. TIC adheres to the certification processes that RMCAO instills which helps to prove to contractors that TIC’s fleet can produce quality concrete. “Once we started working with the Reimers we realized we could bid on projects that we never could before. We could bid on commercial projects – strip malls, big box stores, schools and bridges, places where highly-specified concrete was required.” Today, Steve sits on the Board of Directors for the RMCAO and holds certification from the American Concrete Institute (ACI) which also helps to boost credibility.


Commercial / IndustrialWith more and more large, commercial jobs being undertaken by TIC, the more specifiers and engineers are becoming familiar with continuous mixing technology and with TIC’s resume of varied projects. “We now have pedigree with a steadily longer list of ‘regular’ concrete jobs” says Bob. Steve remarks “the RMCAO calibration process requires that all machines are calibrated by outside testing companies, this speaks to our credibility and having ACI certification on staff at TIC indicates that we’re serious about quality concrete production”.
