Prepare substrate for harbour renovation

Time is money. Thorough, gentle and efficient work is crucial to save costs. DYNAJET high-pressure cleaners mean you can remove concrete, expose the steel reinforcement and remove rust in a single operation.

  • High cleaning and extraction power
  • Low rebound and high area coverage
  • Vibration-free removal
  • Extremely compact machine
  • Variable regulation
  • Great reliability

Vibration-free concrete removal

Port facilities need to be thoroughly cleaned and prepared when being renovated. DYNAJET lets you carry out this preparatory work using a high-pressure cleaner in a single operation using nothing more than water.

The damaged concrete must be selectively and gently removed and the corroded steel reinforcement then completely freed of rust. This preserves the intact and undamaged portion of the substrate. This is the only way to ensure that the bond between the concrete and the reinforcement is maintained and it can be effectively renovated. DYNAJET UHP220 high-pressure cleaner’s adjustable flow rate, pressure and temperature lets you select the perfect setting for every surface. DYNAJET high-pressure cleaners make vibration-free deep removal possible.

Reference about use: DYNAJET UHP170 used in harbour renovation in Namibia

Dilapidated quay and pier facilities in Namibia had to be prepared for renovation keep port operations running. The Namibian building construction industry put its faith in the DYNAJET UHP170 with up to 2,800 bar pressure capacity. The DYNAJET UHP, part of the DYNAJET high-pressure cleaner portfolio, offered precisely the equipment needed for this varying situation: DYNAJET high-pressure technology was chosen to preserve the still intact basic structure of the port areas using vibration-free deep removal (approx. 6-10 cm). This exposed the first steel reinforcement layer and then freed it from corrosion, with huge time and cost savings.

In addition, DYNAJET ultra-high-pressure cleaners’ pressure, flow rate and temperature can be varied for the best results in any environment. This ensures that the DYNAJET UHP always operates highly efficiently and adapts flexibly to different needs. The high-pressure is a universal cleaning and maintenance tool that modern and forward-looking construction site operators will find they cannot do without.
