Since Stonecrest’s conception over 25 years ago, the company has designed thousands of agricultural facilities and has since expanded to include engineering services for bio-energy, commercial and residential sectors.


We have designed agricultural facilities throughout Canada, the United States and overseas. We are experienced and highly respected in the agricultural and engineering fields and have helped establish Stonecrest Engineering as the leading engineering firm specializing in the agricultural sector in Ontario. Our staff works closely with business owners and/or their builders to develop practical, environmentally sound site plans.

Stonecrest Engineering's Owners

Wayne Blenkhorn started Stonecrest Engineering in 1995 with the intent to help his clients with changing regulations in agricultural construction. Wayne worked closely with contractors and farm customers to learn their preferences in construction and was able to provide drawings that were tailored to their style. His belief, and the one he has instilled in his staff, is that we need to learn from the client as much as we are here to provide guidance.

In the past 25 years the company has grown substantially and the relationship with the clients remains the primary focus. In recent years, Wayne has brought Nick Hendry and Bram Van den Heuvel in to the Stonecrest Engineering partnership to continue with his client focused vision and to help grown the business for the next generation.
