High Level Render Cleaning, Cardiff South Wales

Associated British Ports - Queen Alexandra Building, Cardiff Docks

Adams & Hardcastle were approached by Associated British Ports to restore the rendered façade on their Cardiff head office in Cardiff Bay, Queen Alexandra House.  The building also houses Cardiff Councils’ Harbour Authority & UK Dredging.

The building façade had not been cleaned since the building was built some 15 years ago & had a significant level of organic & atmospheric soiling largely infested by black, green and red algae.  Being on the waterfront it had taken a battering from the elements and in some areas the neutral finished render was actually black!

Adams & Hardcastle operators carried out test patches on several different elevations around the estate and through consultation with ABP’s engineering team and our own in house project meetings agreed a suitable product and methodology to use to clean and restore the render to its former glory.

The challenge was to find a product strong enough to kill off the algae infestation whilst posing no risk to the public accessing the Cardiff Bay barrage which QA House is situated next to and not allowing any product to contaminate Cardiff bay itself.

We chose to carry out the project using a combination of technical chemical cleaning coupled with low pressure steam cleaning and good old fashioned elbow grease!

The project took approximately 350 onsite service hours to complete over an 11 day period and included steam cleaning capping stones, restoring the render and cleaning the Cotswold stone coloured paving surrounding the building.

One employee even commented that they had assumed that the paving was grey and was very surprised to see the lovely golden yellow colour exposed underneath the soling, they had worked in the building for three years!

Post project we received the following comment from the Port Director….

“From my perspective the cleaning work was a great success and the building almost looks like new again so we are very pleased with the outcome.

The work itself was well managed and executed, and your staff were very helpful and considerate in working around our daily needs, in fact a lot of work was done over the weekend to avoid or reduce access issues.   We would certainly recommend you to our other ports”.
