Apex Systems Ltd 尖顶系统

In Clear Water Bay District we wer called in to cut through three floors to create a lift shaft.

We used the Braun Wall BWS 12H machine. Using this we wer able to cut Three squares identically in line.

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.

Our coring equipment (above) in association with Thorn Lighting (HK) Ltd is responsible for the 12000 holes drilled in Hong Kong International Airport’s runways, taxiways and aprons.

We were contracted by New Asia Engeineering Ltd. to help leval a series of tennis courts in Sha Tin Garden. A flat surface was needed to apply the new sports coating.

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.

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 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.

Noise was a problem for the owners of the industrial building. They had tenants in the floors above and below, and since some operating 24 hours a day a noisy job was out of the question.

Over Easter 2007, A-Pex sent in a VA 30SH machine – A 300 kg hydraulically propelled floor, equipped with a special drum that shatters each tile into small pieces. By the time the neighbouring offices returned to work after the holiday the 2600m2 job had been completed.

Anti Skid surfaces require vigorous preparation on concrete or asphalt before they are applied. Shotblast is the only method that can abrade the whole surface uniformly.

The photograph is of the shotblasting of asphalt on Waterloo Road in 2002. Aluminium oxide aggregate in an epoxy / bitumen mix was then applied to create an anti skid surface.

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.
