Wecryl Surface Protection System OS 10 ‐ 2.0

Brief description

The Wecryl Surface Protection System OS 10 ‐ 2.0 is a high‐quality, highly flexible PMMA waterproofing resin tested in accordance with the German Committee on Reinforced Concrete (DAfStb) guideline “Protection and repair of concrete components”. This makes the waterproofing system (as a sealing layer with or without embedded fleece) suitable for areas of foot and vehicle traffic, with high crack‐bridging properties under protective and covering layers. The surface can be created with a wide range of colours, patterns or markings. The fact that this system, with its high bonding strength on almost any substrate, is applied as a liquid kit makes it a cost‐ efficient, high‐quality solution, especially for the renovation of multi‐story parking structures.

Areas of application

Surface protection and waterproofing of concrete structural components with separating cracks and regular mechanical stress.

Foot and vehicle traffic 

Parking structures, bridges, trough and tunnel floors

For applications with demanding finish needs

Properties and advantages

  • Highly flexible and crack‐bridging even at temperatures as low as ‐30°C      (Class B 4.2 – dynamic crack bridging as per DIN EN 1062‐7)      (Class A 5 – static crack bridging as per DIN EN 1062‐7)
  • Tested according to Class OS 10 of the DAfStb guideline “Protection and repair of concrete components” (October 2001).
  • Waterproofing layer (PESPL) can be installed as waterproofing of a continuous area without an embedded fleece
  • Fire protection class Cfl‐s1
  • Able to withstand high mechanical stress (for example from vehicles and persons)
  • Fully bonded to the substrate, no seepage
  • Usable on almost any substrate
  • Adjustable slip resistance makes it the ideal solution for parking structures
  • High area coverage due to efficient design 
  • Permanently weather‐resistant (resistant to high and low temperatures, UV rays, hydrolysis) 
  • Resistant to most commonly used acids and alkali solutions
  • Wide range of design options (colour finish, lane markings, etc.)
  • Solvent‐free
