A helipad is a small area of pavement carrying a lot of information. Helipad marking in Australia has to tell a pilot where the landing site is, where its usable edges are, which way it is oriented and, in some cases, how much weight it will take. All of that in a space a fraction of the size of a runway.

This article covers what goes onto a helicopter landing site, what changes when it is a hospital helipad, and what to think about when the markings need renewing.

What helipad marking Australia wide involves

The exact set depends on the type of site and who it serves, but most landing sites carry some combination of:

• The identification marking. The letter H on most sites, or a cross on hospital and medical sites, telling a pilot what they are looking at.
• Perimeter markings. The line defining the edge of the usable landing area, which is what stops a pilot misjudging the boundary against surrounding pavement.
• Touchdown and lift off area markings. The defined area where the helicopter actually sits.
• Final approach and take off area markings. The larger area around the touchdown point.
• Aiming and alignment markings. Where the site has a preferred approach direction.
• Weight limitation markings. Where the structure or pavement has a stated limit, so a crew knows before they commit.

The markings also have to work as a set. Colour contrast against the pavement, consistent line widths and correct geometry all matter, because a pilot is reading the whole pad at once from above rather than scanning it in sequence.

Hospital helipads are their own thing

Hospital and medical landing sites are the ones we are asked about most, and they carry a few extra considerations.

The red and white cross identification is the obvious difference, and it is the marking people picture. Beyond that, medical sites are often built into constrained locations, on structures, or beside buildings that create their own approach limitations. The markings have to be exactly right because there is less margin available.

They also tend to matter at the worst possible time. A retrieval crew arriving at night in poor weather is not the moment for a faded perimeter line. Hospital pads are a strong candidate for planned marking maintenance rather than reactive repainting.

We marked the helicopter pad at Bowen Hospital in Queensland, which is the photograph at the top of this article.

Private, industrial and remote landing sites

Not every landing site is at a hospital or an airport. We also see:

• Mine site and resources landing areas
• Remote community and station landing sites
• Emergency and secondary landing areas at regional facilities

The requirements vary depending on whether the site is registered and what operations it supports. If you are not sure what applies to your site, that is worth establishing before the markings are laid out, not after.

Where helipad marking goes wrong

Three things account for most of the problems we come across.

Contrast loss. A white marking on light grey concrete has limited contrast when new and very little once it has weathered. This is the most common issue on concrete pads.

Drift over successive repaints. Each repaint follows the last one rather than the correct geometry, and over several cycles the layout wanders. Repainting from the existing markings preserves the error.

Wrong paint for the surface. A pad is a small area and it is tempting to treat it as a minor job. It still needs a product suited to the surface and the exposure, applied properly.

How we approach it

We mark new pads and refresh existing markings that have worn back. Where the layout has changed or previous work has built up, we carry out line marking removal first rather than adding another layer over the top.

We use Wattyl paints across all our line marking, tested to meet the harsh requirements of Australia and New Zealand’s environment. Landing sites in northern Australia take heavy UV and heavy wet seasons, and the paint has to hold up to both.

Where a site sits within an aerodrome, working airside brings its own requirements. Our linemarkers hold RED ASIC cards for airport access and our team includes CASA certified air and ground radio operators. We carry 20 million dollar public liability insurance.

Helipad marking Australia wide, including the hard to reach sites

Over more than 25 years we have worked at regional, mining and remote sites across Queensland, the Northern Territory, New South Wales, Victoria, South Australia and Tasmania, as well as in Papua New Guinea. Remote sites are normal work for us rather than an exception, which matters when your landing site is a long way from a capital city.

Getting your landing site marked

Whether it is a hospital helipad, a mine site landing area or a pad at a regional aerodrome, we can mark it new or bring existing markings back.
