Building Olympic Ice: The Challenge Behind Milan-Cortina’s Rinks
As preparations intensify for the upcoming Winter Olympics, the meticulous art of crafting perfect ice surfaces is receiving heightened attention. Milan-Cortina is set to host its first Olympic events at temporary venues, raising both excitement and challenges for ice technicians known as ‘ice masters.’
Why It Matters
The construction of Olympic-quality ice is crucial for ensuring fair competition among athletes in disciplines such as curling, figure skating, and ice hockey. With the games being held at a temporary venue for the first time in Winter Olympics history, the success of this endeavor could redefine how future events are organized and executed.
Key Developments
- The ice hockey arena in Milan-Cortina was built from the ground up, facing delays and substantial last-minute adjustments.
- Five centimeters of insulation and a vapour barrier ensure the structural integrity and temperature maintenance necessary for quality ice.
- Glycol-filled mats help keep the ice surface cold, while layers of water create the optimal playing conditions.
- Resurfacing equipment, notably Zambonis, will be actively employed to maintain ice quality throughout the events.
- Ice master Mark Messer acknowledged the challenges of implementing ice production at such a large scale and within a tight timeframe.

The Ice-Making Process
The preparation of Olympic-level ice begins with a base layer of five centimeters of insulation, installed over a concrete foundation. Following this, a vapour barrier is added to prevent moisture from interfering with ice quality. Engineers then lay mats filled with glycol to maintain the necessary cold temperatures. The perimeter of the rink is enclosed with boards and glass walls, and roughly two inches of water is added above the glycol mats to form the initial ice sheets.
Once these sheets are frozen, the surface is coated in a white sealant, and official ice hockey lines and logos are painted in. Finally, an additional three to four centimeters of water is layered on top, establishing a smooth and playable surface. The entire temperature of the rink is meticulously controlled, kept between -5 and -4 degrees Celsius.
Maintenance and Challenges
The maintenance of the ice during the games is equally crucial. Resurfacing machines, commonly referred to as Zambonis, are scheduled regularly to shave off the existing ice’s top layer and create a new, smooth surface for athletes. Mark Messer, an ice master overseeing long track speed skating, expressed that adapting to a new ice-making system for such a prominent event has its challenges. He noted the unique pressure of preparing ice at an Olympic venue that has not previously utilized a temporary location on this scale.
Context & Previous Events
This Olympic event marks the first instance where long track speed skating will be held at a temporary venue during the Winter Games. Previous competitions have typically relied on permanent structures, making this endeavor notably innovative and unprecedented.
