Waterproofing: our solutions for your site constraints

What is waterproofing and why is it essential?

L'waterproofing refers to the ability of a system, material or assembly to prevent the passage of liquids, gases, dust or contaminants. 
In industry, guaranteeing a perfect seal is a major challenge. crucial to the safety, performance and durability of products or installations. 

Industrial sealing doesn't just concern visible fluids: it also applies to the protection against ambient humidityThe risk of electric shock, splashes, micro-leaks, electrical interference, even heat or noise penetration. 

It is therefore omnipresent in : 

  • The sensitive electronic or electrotechnical systems
  • The mechanical or multi-material assemblies
  • The damp, submerged, pressurised or weather-exposed environments
  • The processes requiring perfect cleanliness or stability 

The aim is simple: to avoid leaks, infiltrations or performance losses that could lead to production stoppages, technical failures or regulatory non-compliance. 

Industrial sealing applications

Electronics and electrical engineering 

  • Tightness of electronic enclosures (IP65 to IP68) 
  • Filling sensors, relays or modules 
  • Protection against moisture, dust and chemical splashes 

Components encapsulated or protected by resins or sealants guarantee increased longevityeven in damp, outdoor or vibrating environments. 

Aerospace, rail, defence 

  • Structural waterproofing of composite or metal components 
  • Protection of on-board harnesses, junctions and connectors 
  • Fire-smoke, vibration and high-temperature standards 

In these sectors, it is synonymous with safety and regulatory complianceThese are critical environments subject to severe thermal and mechanical cycles. 

Mobility, cars, transport 

  • Sealing of glazing, doors, batteries and electrical modules 
  • Compatibility with automated or manual fastening systems 

Waterproofing solutions must also take into account the constraints of recyclability, dismantlability or aesthetics. 

Industry, construction and public works, energy 

  • Sealing of boxes, electrical cabinets, solar installations 
  • Solutions for expansion joints, cracks, ducts or cable passages 
  • Resistant to weather, UV, chemicals and extreme temperatures 

Here, priority is given to long-lasting holdthe versatility in materials and rapid implementationeven on site.

FAQ - Waterproofing

This is a technical solution (mastic, glue, tape or resin) used to block the passage of liquids, gases, dust or contaminants between two materials or across an interface, while resisting mechanical, chemical or thermal stress. 

A sealing compound fills a joint or void without necessarily creating a structural link. A waterproof glue provides both mechanical adhesion and a waterproof barrieroften on highly stressed parts. 

Metals (aluminium, stainless steel), plastics (ABS, PP, PC), composites, wood, glass, technical textiles, etc. We offer specific solutions for each type of substrate. 

The most common are : 

  • IP65 to IP68 for electrical enclosures 
  • UL94 for fire resistance 
  • REACH / RoHS for regulatory compatibility 
  • EN45545 for transport 
  • ISO 11600 for sealants 

The choice depends on : 

  • The environment (humidity, temperature, chemical exposure) 
  • Materials to be assembled 
  • Type of stress (mechanical, vibratory, thermal) 
  • The method of application (manual, robotic, in-line)
