Several concrete structure elements needed to be repaired at a flyover. These spots were difficult to reach at a depth of 1 meter. Access to these spots was also limited with a height of 25 cm.
Doornbos advised a specific water jetting setup to be able to reach these spots and do the job quickly, effective and safely. Work was executed using a 2500 bar high pressure pump and a spray gun with 'demolition nozzle' on a specially designed frame to keep the setup in position. This combination resulted in a 'hammer drill effect' which demolished the concrete even quicker, while keeping the reinforcement unaffected. The frame was especially designed for ergonomic benefits for the operators.
For optimal safety, Doornbos also supplied the high quality personal protective equipment from specialist supplier TST Sweden.
