Admiralty Car Park, Queensway
Admiralty Car Park in Queensway has had it’s fair share of PU coatings over the years. A-Pex were contracted to remove the most recent coating that had been damaged through damp seeping through the concrete floor. Upon inspection we determined that the PU that would have to removed was as thick as a car tyre.
A special type of drum was set up on the planing machines so that it could get underneath the PU and pull it upin the same way as a carpet would be pulled up.
Shotblast was used after the removal to provide an even cleaner surface with an improved bond for the waterproof membrane and coating.

At car park number 4 at Hong Kong International Airport the important issues were noise and speed. Noise because of the proximity of the Regal Hotel only metres away and speed due to the risk of rain the contractor needed to be in and out in the quickest possible time.
Working 12 hour shifts A-Pex completed the whole 6000m2 within 6 days.
Our super quiet Shotblast machine produces a maximum of 82 dBA @ 5 metres – which is not much higher that a household vacuum cleaner.
