Bölschestraße residential and commercial building flat roof

The bitumen roof waterproofing of a residential and commercial building on Bölschestraße in Berlin was showing cracks and brittleness so it urgently needed to be repaired. The real estate owner, HCP Invest GmbH & Co KG, was particularly interested in finding an economical solution. The contractor, the local company ABD Bedachungen GmbH, therefore recommended fast-setting
liquid applied waterproofing based on polymethyl methacrylate (PMMA). The fleece-reinforced Triflex ProTectwas used here. Its low weight per unit area meant that the roof waterproofing system could be applied to the existing bitumen membranes without any need for demolition. Even at cold temperatures. The special resin also safely integrates complicated details such as securants, fans and skylights into the waterproofing. The traffic-yellow coloured anti-slip coating Triflex Cryl SC 237 was used to create the maintenance paths.

Refurbishment requirements

  • Reliable protection against moisture ingress
  • Highly resistant to chemical, mechanical and thermal influences
  • Temporary protection against accidental falling instead of scaffolding
  • Application on existing substrate without any need for demolition
  • Elastic material
  • Integration of numerous connections and details
  • Application during the cold season
  • Anti-slip coloured maintenance paths

Refurbishment steps overview

  1. Sweeping of the roof covering and removal of loose components
  2. Refurbishment of any existing bubbling in the bitumen membrane
  3. Sealing of all details and penetrations with Triflex ProDetail and Triflex Special Fleece
  4. Sealing the surface with Triflex ProTect and Triflex Special Fleece
  5. Masking of maintenance paths and coating with Triflex Cryl SC 237 in traffic-yellow

TRIFLEX PROTECT MEANS INCREASED SECURITY THANKS TO THE SYSTEM-COMPATIBLE, SEAMLESS INTEGRATION OF CONNECTIONS AND DETAILS. THE CLEAR DEFINITION OF THE MAINTENANCE PATHS ALSO REDUCES THE RISK OF DAMAGE TO THE ROOF COVERING BY OTHER TRADESPEOPLE.
