There are many advantages to hydro demolition. In the case of Keeyask, a 24-inch intake pipe froze and destroyed an eight-foot-thick concrete pier. Instead of letting the pier fall to the ground and causing more damage, managers opted to utilize Hydrodemolition to get rid of the damaged section. Despite logistical difficulties, the company used its equipment and extensive experience to overcome the challenges of this difficult project.
Hydrodemolition Vs Sandblasting
Hydraulic demolition uses high-pressure water jets to tear down concrete. Unlike jackhammering, hydro demolition is environmentally safe. The water jets leave no trace of debris, and the water can be captured afterward to reduce the risk of contamination. Hydrodemolition also reduces the likelihood of injury, reducing the risk of Hand-Arm Vibration Syndrome (HAVS).
While both methods can remove concrete and masonry, robotic hydrodemolition is the preferred method for coating removal. It provides a safer, more efficient, and environmentally friendly option for removing coatings that are not removed by lower pressures. It can also remove coatings and aid adhesion. The cost of hydro demolition is less than half of sandblasting.
