County Road 31 Culvert

April 14, 2025
The removal and replacement of the Irwin drain culvert was successfully completed in November 2024 by Jones Group Inc. at the intersection of County Road 31 and County Road 8. Coldstream Concrete Ltd. was hired to manufacture and deliver 23.2 meters of a 5.0m x 2.8m box culvert. The precast concrete culvert was designed with custom features, including skewed ends, recessed connection plates, approach slab seats, and integrated infill sections, all cast directly into the culvert units. The entire culvert installation was efficiently completed in a single day.

Paris Meadows Subdivision

April 14, 2025
This vibrant community hub, spanning 57.5 hectares, includes 309 residential lots and 14 commercial/industrial blocks, providing homes for around 1,000 residents. The land was developed into eight streets, with the addition of a new pumping station and a 6-cell stormwater management pond. Featuring a wide range of Coldstream Concrete’s standard products, we successfully installed 3.5 kilometers of reinforced concrete pipe ranging from 300mm to 1800mm in diameter, multiple outlet headwalls, and over 350 round and square precast structures.

Western University Steam Tunnel

April 14, 2025
This multi-year project, which began in 2023, is now entering its third year of construction. The project is being completed in phases with the assistance of London-based installation contractors. Every effort has been made to minimize any disruptions to students studying on campus. Phase 1 involved the installation of 64 meters of 1.5m x 0.9m steam tunnel with removable concrete lids. Phase 2 is currently in progress and, once finished, will extend the tunnel by an additional 130 meters, including the addition of a new hub to direct steam in four directions. To date, Coldstream Concrete Ltd. has produced 79 tunnel segments and 68 lids.
