Ottawa-based contract electronics manufacturer (CEM) OCM Manufacturing, has signed an agreement with Giatec Scientific Inc., to manufacture the firm’s SmartRock electronic concrete temperature monitoring device.

SmartRock is a rugged waterproof wireless sensor for monitoring the temperature and maturity of concrete from fresh to hardened stage. This information is analyzed using a mobile app to estimate the real-time strength of concrete.

George Henning, president of OCM Manufacturing, says his firm is excited to be working with Giatec on such an innovative product. “We specialize in the manufacture of electronics products that are often targeted at important niche or under-served markets. SmartRock is an excellent case in point and we look forward to a long relationship with Giatec Scientific.”


The SmartRock sensor is placed directly in formwork at the pouring stage and enables wireless and continuous monitoring of concrete temperature and strength, which is critical to the successful utilization of concrete in modern structures. The product has several benefits, such as optimization of formwork removal times, more accurate assessments of load on structures and it enables the ongoing adjustment of curing temperatures. Data is recorded on the SmartRock memory and downloaded and shared via a smartphone or tablet computer on-site during concrete setting and hardening.

Dr. Aali R. Alizadeh, CEO of Giatec Scientific, says he was impressed with OCM’s capabilities and service from the outset. “The OCM team worked with us to ensure that they not only had a thorough understanding of our product, but that we had the most efficient manufacturing process for our needs.”
