Kranichdamm Salzgitter apartment house balconies

After more than 60 years, the old surfaces of the balconies of an apartment building in Salzgitter had become worn out. They were peeling and could no longer reliably protect the construction beneath from the effects of the weather. Penetrating moisture
had led to concrete and water damage, some of which appeared in the owners' living rooms. In addition, severe signs of wear marred the appearance of the balconies. Salzgitter Wohnungs-GmbH as administrator commissioned the refurbishment of all the balconies in the name of the apartment owners association Wohnungseigentumsgemeinschaft (WEG) Kranichdamm 35-41, Salzgitter. Extensive waterproofing, concrete and painting work was required to create a functional protection layer with the repair to be carried out from a single source. Rainer Bothe Malerbetrieb GmbH, Bad Harzburg, recommended to the client that the best way to achieve permanently durable waterproofing was a solution using the balcony waterproofing system Triflex BTS-P with a polymethyl methacrylate (PMMA) resin base.

Refurbishment steps overview

  1. Deconstruction of the balconies including the asbestos content of the parapet
  2. Repair of the raw concrete floor with new screed.
  3. Abrading the mineral substrate
  4. Priming the surface using Triflex Cryl Primer 276
  5. Detail waterproofing of wall connections, floor drains and circumferential steel edge with Triflex ProDetail

  7. Coating of the surface with Triflex ProFloor RS 2K
  8. Finishing the surface with Triflex Cryl Finish 205 and Triflex Chips Design (black and white)

THIS WAS A COMPREHENSIVE PROJECT INCLUDING REPAIRING THE CONCRETE, SEALING AND DESIGN, WHERE THE CLIENT WAS LOOKING FOR A LONG-TERM SOLUTION. THE WORK WAS DONE FROM ONE SOURCE AND SOLVED THE PROBLEM PERMANENTLY.
