Taites Cairn Tunnel
This contract will be done with the newly purchased VA25 Twin (Pictured). This Swiss made machine uses 2 drums. The first drum removes the thick part of the thermoplastic while the second drum cleans the remainder of the surface to leave a coarse, clean finish. This machine is up to 12 times quicker than the methods commonly being employed in Kong Kong presently.

Hong Kong International Airport
Apex Systems were hired to grind the 30000 metres of joint walls after the contractor had removed the failed expansion joint.
3 machines and 3 men were able to diamond grind the 30mm deep on both sides. Although the time frame was tight (10am-3pm) we were able to complete 2500 linear metres of joints per day.

Container Terminal, Nine Tsing Yi
The main contractor called us to find a solution to the widespread problem of rain damaged concrete over a large part of the terminal.
As well as being uneven, the concrete failed the ‘sand patch test,’ a test devised by the highways Department to determine it’s anti-skid
value. From September to December 2003, using grooving machines fitted with Tungsten Carbide blades we repaired all the damaged areas to the government standard, in time for the whole area handover.
Mega Box
In March 2007 we were called into the huge retail and office complex, Mega Box
On floors 3 & 4, the surface was up to 25mm high in places, which meant the laser guided screed would be too thin.
The VA30SH planer was used with an adapted drum. With 6 passes this powerful machine was able to remove the necessary 25 mm.
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.
