WorkSafe BC Hydrodemolition Piece

Walco Industries Ltd. stepped into the world of hydrodemolition in 2017. Hydrodemolition is a concrete removal technique that uses high-pressure water to remove damaged or deteriorating concrete from a surface. It is highly precise, making it ideal for applications where the structural integrity of the remaining concrete needs to be maintained. The water jet is adjustable and can be used to selectively remove damaged areas while preserving sound concrete. Hydrodemolition is becoming increasingly popular for a range of applications including bridge deck repair, piles, dam spillways and columns. Read more here!

Using Lessons Learned From Penstock Cleaning To Save Time, Money

Cleaning the inside of penstocks that supply water to hydroelectric powerhouses can be a time-consuming and labour-intensive process. This case study illustrates how it was possible to cut the time required to perform this work by more than 80% and reduce man-hours by about 75%. 

The work to be discussed took place at the Bridge River hydroelectric complex in British Columbia, Canada. Bridge River is a mid-sized stream about 120 km long, flowing southeast from the Coastal Mountains and joining the Fraser River near Lillooet. The 492 MW Bridge River hydroelectric complex consists of three dams and stores water for four generating stations. The system uses Bridge River water three times in succession to supply 6% to 8%of British Columbia’s electrical supply.
