Hangar Linate Prime: High-Performance Waterproofing for Exclusive Aviation Facilities

Located in Lombardy, within the strategic aviation hub of Linate Airport, the Linate Prime hangar stands as a benchmark in the world of private and executive aviation.
Designing and protecting a structure of this scale requires advanced technical waterproofing solutions capable of guaranteeing durability, safety, and long-term performance — especially in a high-value, high-exposure environment where reliability is essential.

The Challenge: Protecting a Strategic Aviation Structure

Aircraft hangars are subject to some of the most demanding environmental and structural conditions:

• Extensive roof surfaces exposed to weather and thermal fluctuations
• Significant structural movements due to large spans
• Strict safety standards required in aviation environments
• Minimal tolerance for maintenance interruptions, given continuous operational needs

For a premium facility such as SEA Prime, the waterproofing system needed to ensure maximum reliability, long-term protection and performance continuity.

Project Objectives

The intervention aimed to deliver:

• Long-lasting waterproof protection across wide roof areas
• High resistance to thermal expansion and structural stress
• Mechanical durability and weather resistance
• Easy future inspection and maintenance
• Full alignment with aviation and airport safety requirements

In airport settings, reliability is not optional — it is mandatory.

The Technical Solution

TTo meet these requirements, the project adopted a high-performance liquid waterproofing system developed by Winkler.

Liquid membranes offer decisive advantages for hangar structures:

• Seamless application, with no overlaps or weak points
• Excellent adhesion to a variety of substrates
• Adaptability to complex roof details and structural joints
• Fast installation, minimizing downtime and operational disruption

The elastomeric formulation provides the flexibility required to accommodate structural movements without cracking or loss of performance.

  Performance Advantages

The selected waterproofing system offers:

• Total waterproofing, even under standing water conditions
• Outstanding UV exposure and weather resistance
• High elasticity under thermal stress
• Long service life with reduced maintenance cycles

For executive aviation environments, protecting the building envelope – and the high-value aircraft inside- is a strategic investment.

Results Achieved

The Linate Prime Hangar intervention provided:

• A continuous, high-performance waterproof surface
• Enhanced roof durability
• Streamlined maintenance management
• Improved protection for valuable aviation operations and assets

FAQ – Waterproofing for Airport Hangars

Why choose a liquid waterproofing system for an aircraft hangar?

Liquid-applied systems create seamless membranes, eliminating overlaps and minimizing weak points – a major advantage on very large surfaces.

Is the system resistant to thermal expansion?

Yes. Elastomeric formulations are designed to accommodate structural movement caused by temperature variations.

Does it reduce maintenance requirements?

Yes. High UV resistance and weather durability significantly extend maintenance intervals.

Is the system suitable for large-span structures?

Absolutely. Liquid waterproofing performs exceptionally well on wide, uninterrupted roof areas, typical of airport hangars.
