Waste Recycling biomass, Ian Moncrieff

"Canadian Biofuel Inc. was looking for a cost effective and practical solution for its start-up plant in Springford Ontario. Located on a former grain handling facility, we were able to utilize the asphalt pad as the base for the MegaDome® building. The building contractor was quick and efficient and we were able to begin fabrication of the feedstock storage area and the pellet production line room under the new dome. The fabric cover provides great lighting and weather protection, more than enough ceiling height. All of this for a reasonable cost and on time completion. Due to an increase in export of our pellet products we will be expanding the existing building by adding another 54 feet to one end in order to store enough feedstock. We certainly look forward to use a MegaDome® again soon!"

Riding arena, Jesse James

The building of our arena project was completed in October of last year and has been in use ever since. Lots of people have come by just for a look as well as the usual flow of friends and business associates. Many of those have remarked on the "beautiful building". Previously, I never thought of a covered arena as beautiful, but I must agree with them.

Personal Storage, Allen Paul

It was always a dream to have my own hangar to store gliders and equipment out of the weather and when I saw what a MegaDome® building could provide, I thought it was time to turn that dream into reality. I was looking for a bright clear span functional low maintenance facility that could be relocated if necessary. The gothic featured roofline was pleasing to the eye and the almost vertical sidewall profile meant that I would be able to make great use of the floor space. Once that space was full, I had the option of storing additional gliders above floor level using simple hoists running from the building arches. Furthermore the design was easily adaptable to a variety of large entrance doors to facilitate moving equipment in and out.

Commercial Storage, DCR Logistic

In terms of value for money, a MegaDome® offers much more than other buildings! We are particularly pleased with the MegaDome® cold storage solution: the interior is not any more humid than normal, while rain and wind control is total. The MegaDome® structure offers a spacious work area, which greatly facilitates the organization of the stored material. We like the exterior look and the city regulations does not prevent us from building additional domes.

Agriculture & Livestock, Dairy, Don Williams

I am extremely impressed with our MegaDome® and would recommend it to anyone! We wanted the best value and when looking for a suitable structure, no one else seems to do better on price and still supply what we wanted. To be honest this was the only building that Ken Tulloch suggested that would work for what we needed. One of the cheaper buildings may have worked, however we wanted the best value.
