We recently undertook a challenging slip repair retaining wall construction project in Piha, which required us to employ our technical expertise and innovative problem-solving skills.
The first wall we built was constructed using the Redi-Rock system, which is renowned for its ability to offer superior stability and support, especially in areas where the ground is unstable. Given the inherent instability of the ground at the site, the use of the Redi-Rock system was a crucial decision that enabled us to provide a solid façade with geo grid material tying the Redi-Rock system into the now stable ground.
The second wall we constructed was a UB steel wall, which presented us with a unique set of challenges compared to the Redi-Rock system.
To begin with, we had to employ auger drilling to create multiple deep holes for the UB beams to go into. Additionally, the site's limited space and difficult access made it particularly challenging for our team to manoeuvre and operate the large gear required for the installation of the steel UB wall. However, with our extensive experience and creative problem-solving skills, we were able to devise an effective solution to overcome these challenges and execute the project with precision and accuracy. As a result, the wall was perfectly aligned and level, providing an excellent and robust solution to the slip repair.
