Roof Waterproofing

Long-lasting protection of industrial roofs and terraces against precipitation and weather; renewal solutions planned without stopping your operations.

Why roof waterproofing

The facility’s hardest-working surface is above your head.

A roof is the surface that meets rain, snow, wind and sun all at once, working under the building’s harshest conditions. In an industrial facility, water entering through the roof is not merely a building problem; it directly threatens the product, the equipment, the stock and production continuity. The cost of a seemingly small leak to the facility is usually greater than the cost of the waterproofing itself.

Our first step in roof work is to establish where the water actually enters, because the spot where a leak shows inside and the point where water enters the roof are rarely the same. Once the source is found, we weigh the options from localized repair to comprehensive renewal according to the roof’s condition, and plan the application without stopping your operations.

What sets this system apart
  • Source detection first: The basis is the point where water enters, not where the leak shows.
  • Application while operations continue: Phased planning without disrupting production and storage.
  • Focus on detail points: Gutters, parapets and penetrations are the roof’s most critical zones.
  • A long-life approach: Measured intervention that takes the roof’s remaining life into account.
Where it is used

On every surface that meets the water first.

Roof waterproofing requires a holistic view, from wide flat surfaces down to the smallest transition detail.

Water finds the weakest point; the system leaves none.

A roof waterproofing’s performance is decided not on the wide surfaces but in the details. While each layer performs its own duty, the system’s integrity is completed by continuity at gutters, parapets and penetrations.

  • Single-ply membraneKeeping the water away from the structure: the layer carrying the system’s real duty.
  • Substrate layersThe layers beneath the membrane, defined by the system build-up.
  • Structural roof deckThe structure the system is built on, its condition assessed beforehand.

Key properties

What is expected of a roof waterproofing.

Uninterrupted protection

Protects the entire facility under a single continuous covering.

Weather resistance

Long life against sun, precipitation and temperature swings.

Fit for ponding zones

Safe behavior where water lingers.

Verified details

Inspected continuity at gutters, parapets and penetrations.

Operations-friendly application

Carried out in phases, planned, without stopping production.

An easy-to-maintain surface

A roof surface easy to inspect and maintain periodically.

Scope scaled to use

As the roof’s use increases, so do the system’s requirements.

The classification below is indicative only. The final system is determined by assessing the roof’s existing condition, its use and the climate conditions on site.
